This solution is designed for organizations seeking to enhance their identity management processes while ensuring compliance with stringent regulatory standards such as GDPR and SOC2. By offering a flexible deployment model, FusionAuth allows users to maintain control over their data residency, whether in the cloud, on-premises, or in hybrid environments. Targeted towards developers and organizations that require robust identity solutions, FusionAuth is particularly beneficial for businesses experiencing rapid growth or those that need to streamline their authentication processes. Its API-first architecture enables organizations to embed identity management directly into their existing workflows, reducing the operational burden associated with traditional identity providers. This capability is especially valuable for companies that wish to eliminate the complexities and costs associated with maintaining homegrown authentication systems. Key features of FusionAuth include its flexible deployment options, which empower organizations to choose how and where they host their identity management solution. This flexibility is complemented by an API-driven architecture, where every feature is accessible through APIs, allowing for seamless integration and management of identity as part of the overall infrastructure. This approach not only enhances developer velocity but also ensures that organizations can adapt their identity solutions to meet evolving business needs without being locked into a single vendor's cloud. Additionally, FusionAuth offers predictable pricing models that help organizations avoid unexpected costs commonly associated with monthly active user (MAU) surges. This transparency in pricing is a significant advantage for businesses looking to scale without incurring excessive expenses. The platform has demonstrated its effectiveness across various industries, with notable success stories highlighting its ability to handle massive traffic surges, reduce operational bottlenecks, and lower engineering burdens. For instance, Bilt leveraged FusionAuth to manage high traffic volumes while ensuring compliance with data residency requirements. Similarly, Vatix transitioned from a cumbersome homegrown system to FusionAuth, enabling their Customer Success team to onboard clients quickly and efficiently. UrbanSitter's implementation of FusionAuth significantly reduced their authentication development time, allowing them to focus on core product innovation. These examples illustrate how FusionAuth not only enhances security and compliance but also drives operational efficiency and cost savings for organizations across diverse sectors. ## FusionAuth Pros & Cons **What users like:** - Users appreciate the **ease of use** of FusionAuth, finding it simple to set up and manage.

A Mixed Bag with FusionAuth **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** March 25, 2025 **What do you like best about FusionAuth?** I really appreciate the customization FusionAuth brings to the table - it’s a standout feature that gives you the flexibility to mold it to your specific needs. The model is well-designed, and the feature set is impressive, covering a lot of bases for authentication and user management. It feels developer-friendly, which makes integration into projects smoother and more enjoyable. **What do you dislike about FusionAuth?** Despite its strengths, there are some frustrating drawbacks. The API breaking between releases is a big issue - it’s disruptive and adds unnecessary rework. I also found the authorization customization lacking; there’s no easy way to implement permission-based or attribute-based authorization, which feels like a missed opportunity for a service like this. On top of that, the API can be unreliable. For example, when deleting a user from a group, I’ve seen inconsistent results—sometimes it removes their roles, sometimes it doesn’t, and it’s unpredictable. These issues make it harder to rely on consistently. **What problems is FusionAuth solving and how is that benefiting you?** FusionAuth is solving problems related to authentication, authorization, two-factor authentication (2FA), and single sign-on (SSO) by offering a system that manages user logins, assigns basic roles, provides 2FA options like Google Authenticator or SMS, and enables SSO across applications using standards like OAuth2 and OpenID Connect. For me, this means I can offload these identity management tasks without building them from scratch, which reduces development time. However, the inconsistent API behavior - like unpredictable role deletions when removing users from groups - and limited authorization flexibility require me to spend extra effort on workarounds or adjustments. **Official Response from Story Tweedie-Yates:** > Thank you for the feedback and I apologize for some of the technical troubles that you’ve had. I wanted to take an opportunity to address some of the concerns you brought to our attention. Typically our API rarely changes (we occasionally may add parameters or additional API endpoints but the existing functionality rarely changes). Not to say it never does but we’d be very interested in determining when and how this occurred for you. With that, if you would not mind sharing the API endpoints that gave you trouble on our Community Forum (https://fusionauth.io/community/forum/) we’d be interested in taking a look. If you believe you have found an undocumented bug you can also file an issue here (https://github.com/FusionAuth/fusionauth-issues/issues/). Regarding your comment about roles and groups, I agree that aspect can be confusing at times. You can find a description of what happens with roles when removing a user from a group here (https://fusionauth.io/docs/apis/groups#remove-users-from-a-group). The major take away is how the roles were applied to the user originally. If roles were originally applied to a user upon registration to an application, manually via the FusionAuth Admin UI, or by using the User API, adding or removing them from a group will not affect those roles. If roles were added when adding a user to a group, then removing that user from the group will also remove the roles. I hope that provided more clarity and please don’t hesitate to post in our Community forum (https://fusionauth.io/community/forum/) if you have additional questions. ### 2. Fusion Auth with Verifast **Rating:** 4.5/5.0 stars **Reviewed by:** Hrayr M. | Product Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** October 16, 2024 **What do you like best about FusionAuth?** Very easy to set up, and get running. We have a simple use case that most other products over-engineered. Still very good **What do you dislike about FusionAuth?** Nothing negative comes to mind. The setup was great, and support was very helpful getting us integrated **What problems is FusionAuth solving and how is that benefiting you?** We have clients that need to use their existing SSO providers (Entra, Okta, etc) with our platform, and we would ned to authorize those users on our end. It has helped our clients feel secure and us to close deals. ### 3. FusionAuth Platform Review: A Developer-Friendly, Secure IAM Solution for Modern Applications **Rating:** 4.5/5.0 stars **Reviewed by:** Thilina M. | Senior Tech Lead , Mid-Market (51-1000 emp.) **Reviewed Date:** June 20, 2025 **What do you like best about FusionAuth?** FusionAuth comes highly recommended as a secure, flexible, and production-ready identity and access management (IAM) solution. It's perfect for projects that need scalable identity services, complete with full Active Directory and LDAP support, multi-tenant management, and tools designed with developers in mind. **What do you dislike about FusionAuth?** All good. Still not found any issues in FusionAuth **What problems is FusionAuth solving and how is that benefiting you?** Unified Identity Management Problem: Juggling authentication across various applications—whether they’re web-based, mobile, or APIs—using custom authentication logic can lead to errors, security issues, and scalability challenges. How FusionAuth Helps: FusionAuth streamlines user authentication by leveraging industry standards like OAuth2, OpenID Connect, and SAML, creating a cohesive identity platform for all our applications. ### 4. It's a game changer **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Small-Business (50 or fewer emp.) **Reviewed Date:** May 22, 2025 **What do you like best about FusionAuth?** Our company used to use Auth0 both in development and in production, and although it was nice to have something cloud based, it lacked some customization options we were really seeking. Fusion Auth was not only simple to setup and deploy, it's made our process for hooking into existing systems. We use this system in all of our tools, both customer and internal, and it's the bee's knees! **What do you dislike about FusionAuth?** The UI is a bit of a learning curve, but once you understand how it operates, you'll be flying through those windows in no time. **What problems is FusionAuth solving and how is that benefiting you?** We had some other systems that weren't compatible with the feature-set offered by Auth0 and FusionAuth ticked every box. Could not recommend this more! ### 5. FusionAuth is a solid authentication provider with fair pricing **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Music | Mid-Market (51-1000 emp.) **Reviewed Date:** March 07, 2025 **What do you like best about FusionAuth?** FusionAuth is a solid authentication provider with fair pricing when compared to other providers. It is fully feature, offering authentication methods ranging from classic user/password to magic links and social IDPs. It is easy to use, easy to integrate and implement thanks to the technical resources they provide, both in the form of documentation and subject matter experts. As an Enterprise client, we have access to a Slack channel allowing us to get quick and responsive support from the FusionAuth team. FusionAuth Cloud is a robust solution that can be used to authenticate hundreds of thousands of users on a daily basis. **What do you dislike about FusionAuth?** The Terraform provider to manage the FusionAuth deployment configuration sometime lags behind software releases leading to some issues when environments are strictly managed via Infrastructure as Code practices. Some customization and configuration options can only be defined at the Tenant level which can lead to some pain points when it comes to meeting some product or business requirements on an application-per-application basis. The FusionAuth Cloud versions lacks some monitoring options like Prometheus that are available when self-hosting. **What problems is FusionAuth solving and how is that benefiting you?** FusionAuth Cloud allows our business to provide secure, state of the art authentication to our users without the need to develop a significant authentication and security expertise in house. The Cloud version is also very stable and robust which allows us to have peace of mind when it comes to the availability of our authentication platform. ### 6. Great tool to put OAuth2 in place **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** April 23, 2025 **What do you like best about FusionAuth?** The best thing about FusionAuth is all the explanations it comes with. It allowed less experienced members of our team to understand how a secure OAuth2 system/procedure works thanks to the multiple graphs provided. The integration wasn't too hard either. It's also something you have to put in place once, but will then literally benefit from/use everyday day. **What do you dislike about FusionAuth?** I haven't heard any complaint from the team. However, some members found it to be harder to understand. But, the more experienced members where able to help them thanks to the doc. **What problems is FusionAuth solving and how is that benefiting you?** It is allowing us to put in place a fully secure authentication procedure. No need to worry about the security of the Auth process anymore (since we put FusionAuth in place). ### 7. FusionAuth improves my productivity while keeping my applications secure **Rating:** 4.0/5.0 stars **Reviewed by:** Marc F. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** October 05, 2025 **What do you like best about FusionAuth?** FusionAuth manages user authentication for my internal and client side applications and what I enjoy the most is how easy it is to set up single sign-on and multi-factor authentication. As once configured, I never have to manage them again. I enjoy the simplicity of the Dashboards and the low frequency of user facing changes. **What do you dislike about FusionAuth?** Troubleshooting documentation, and documentation on tweaking some components, is to me overly complex. I also didn’t anticipate the configuration time due to the state of the legacy systems. Further, I feel reluctant documentation around advanced settings and some high level prompts on what is to come would go a long way. **What problems is FusionAuth solving and how is that benefiting you?** I can now focus my uncovered time on user facing applications, knowing that the security of user access to back-end applications is stream lined and also since FusionAuth improves compliance around security and manages support requests around blocked accounts. ### 8. Dev-friendly SSO solution **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** May 29, 2025 **What do you like best about FusionAuth?** It's easy to set up SSO across apps. Also really simple to download and run locally, which helps us test new versions before making any changes. The hosted login pages are easy to customize, and the docs are pretty helpful. Their support team is knowledgeable and always ready to help out in different scenarios. We're using it mainly for SSO across our homegrown apps. **What do you dislike about FusionAuth?** The Admin UI could be more intuitive. Also, there’s no built-in AWS integration for webhooks, so we’ve had to set that up manually. Would be great if that part was more plug-and-play. **What problems is FusionAuth solving and how is that benefiting you?** FusionAuth is helping us manage user authentication across multiple apps in one place. We are able to set RBAC to users logging into our application suite. Support team is really helpful when it comes to tackling different security scenarios around MFA, tokens etc. ### 9. Fusionauth has helped us implement security flows with great ease **Rating:** 4.0/5.0 stars **Reviewed by:** Shyamal M. | Senior Engineering Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** June 04, 2025 **What do you like best about FusionAuth?** Lots of features especially handling configuring things based on applications, entities and tenants **What do you dislike about FusionAuth?** Custom themes. To leverage existing auth flows without self hosting needs customizing themes in pseudo JavaScript scripts which are not only difficult to achieve but complex to manage. **What problems is FusionAuth solving and how is that benefiting you?** Simplifying configuring security controls and enforcing them. Provides great deal of control. Advanced threat detection is quite handy as well. ### 10. Self service of centralized authentication, secure and flexible **Rating:** 5.0/5.0 stars **Reviewed by:** Jean F. | CTO, Mid-Market (51-1000 emp.) **Reviewed Date:** November 15, 2022 **What do you like best about FusionAuth?** Built with security in mind, self hosted and flexible to serve numerous services that need authentication in a centralized way. Did I mentioned that the Dashboard Rocks?! **What do you dislike about FusionAuth?** Not very easy to install and configure, but I see new alternatives of installation that I haven't tried yet, maybe I just talking junk and should go ahead and try these new ways of having it running ;-) **What problems is FusionAuth solving and how is that benefiting you?** FusionAuth solves security problems allowing administrators to control the requirements of the passwords and centralizing a single-sign-on to all products and services. ### 11. FusionAuth lets me focus on my application, not fighting user management and authn **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Small-Business (50 or fewer emp.) **Reviewed Date:** April 15, 2025 **What do you like best about FusionAuth?** Offloading user account management to FusionAuth allows me to support a ton of different auth providers without having to write endless glue code and inevitably screw up auth and leave my users vulnerable. I really like being able to quickly integrate authentication into my app, create users and have them setup their accounts/reset passwords/setup MFA all without having to stand up my own extra infrastructure to do it. **What do you dislike about FusionAuth?** I've had some frustrating bugs where user account creation failed with limited feedback. I suspect the reasoning is to avoid things like account enumeration, but it makes troubleshooting difficult without a lot of additional logging on my side. **What problems is FusionAuth solving and how is that benefiting you?** I use FusionAuth to manage user accounts (standalone & SSO) for access to our customer portal. ### 12. Simple, Robust, Easy to use **Rating:** 5.0/5.0 stars **Reviewed by:** John L. | Engineering Director, Mid-Market (51-1000 emp.) **Reviewed Date:** May 30, 2025 **What do you like best about FusionAuth?** FusionAuth is easy to use and intuitive. The implementation process was straight forward and the flexibility it provides enables us to provide the functionalities our customers need. **What do you dislike about FusionAuth?** There are occasional minor quirks in the user interface portal page. But nothing that can't be overcome **What problems is FusionAuth solving and how is that benefiting you?** FusionAuth handles our users authentication and allows us to integration our authentication with our clients authentication securely. ### 13. Great Auth Service - Super Reliable and Great Service! **Rating:** 5.0/5.0 stars **Reviewed by:** Gayuru G. | Product General Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** May 25, 2025 **What do you like best about FusionAuth?** The doco is very comprehensive + Reliability is great, and the support has been super responsive to our queries. **What do you dislike about FusionAuth?** There were couple of minor hiccups with an incident but at the end it was handled well by the team and monitors were put in place **What problems is FusionAuth solving and how is that benefiting you?** It replaced our old auth system and we got so many new benefits like MFA and SSO ### 14. A generally decent auth provider for devs and enterprises. **Rating:** 4.0/5.0 stars **Reviewed by:** S W. | Technical & Solutions Architect, Financial Services, Mid-Market (51-1000 emp.) **Reviewed Date:** May 30, 2025 **What do you like best about FusionAuth?** Good documentation. Decent, responsive support with multiple channels. Large and exanding featureset. Straightworward integration with any platform supporting OIDC/SAML. **What do you dislike about FusionAuth?** Some implementation quirks, though generally easy to deal with using support. **What problems is FusionAuth solving and how is that benefiting you?** Unified auth for our platforms and systems for both internal users and customers means that we don't need to roll our own, or manage in multiple places. ### 15. Great auth you can self host **Rating:** 5.0/5.0 stars **Reviewed by:** Will H. | Staff Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 19, 2025 **What do you like best about FusionAuth?** Fusion auths documentation is top notch. My team also finds it amazing to be able to self host so we can control our data **What do you dislike about FusionAuth?** Not being able to create users with a passwordless login flow. Its quite annoying to work around this **What problems is FusionAuth solving and how is that benefiting you?** Easy integration of identity providers saved me a ton of time rolling this myself ### 16. Fusion Auth has been a fantastic tool for us **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Utilities | Enterprise (> 1000 emp.) **Reviewed Date:** June 02, 2025 **What do you like best about FusionAuth?** The tool is very robust and scalable. It has a bunch of features which has been very helpful for the company **What do you dislike about FusionAuth?** Data restoration is up to a certain point only. It would be great to have a feature of reinstating hard deleted data. Reaching out to Fusion auth every time for data restore sounds cumbersome. **What problems is FusionAuth solving and how is that benefiting you?** Fusion Auth has completely replaced siteminder for us and it has been working pretty smoothly since the migration. The integration with LDAP has been very easy and no issues were encountered during the migration. ### 17. Nice product **Rating:** 4.0/5.0 stars **Reviewed by:** Travis D. | Devsecops Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** May 29, 2025 **What do you like best about FusionAuth?** Cost. Dollar for dollar FusionAuth is comparable to Ping and Auth0 and a fraction of the price. Feature parity is on par with those providers, along with reporting. The interface is easy for a new user and the API's provide enough details for most SIEMs. **What do you dislike about FusionAuth?** Lack of out of the box and go. The Core system is easy to implement, and integrating with existing applications is not hard. BUT you have to build out your user experience with it. I don't remember any templates there for this task. **What problems is FusionAuth solving and how is that benefiting you?** Standardize Authentication ### 18. Solid! **Rating:** 4.5/5.0 stars **Reviewed by:** Ashura J. | Csr Contractors, Mid-Market (51-1000 emp.) **Reviewed Date:** September 23, 2025 **What do you like best about FusionAuth?** It's user friendly, offers great flexibility with customizable workflows that are easy to set up & use **What do you dislike about FusionAuth?** Nothing so far. I like the software..... **What problems is FusionAuth solving and how is that benefiting you?** Mostly login issues, ### 19. Perfect Auth Solution for SaaS **Rating:** 5.0/5.0 stars **Reviewed by:** Makarand B. | Founder & Chief Partnership Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** April 14, 2025 **What do you like best about FusionAuth?** FusionAuth delivered a seamless auth solution for our multi-tenant SaaS without any workarounds. Onboarding was fast and smooth, Clean APIs, solving our needs right out of the box. Their customer success team is prompt, helpful, and always available when needed **What do you dislike about FusionAuth?** We found the social login integration to have a learning curve,but we had a alternatitve so did not leverage this feature **What problems is FusionAuth solving and how is that benefiting you?** FusionAuth is solving our multi-tenant authentication challenges by providing a clean, out-of-the-box solution that doesn’t require workarounds. It allows us to manage users and tenants efficiently, with a fast onboarding process. This has saved us time, reduced complexity, and ensured a more secure and scalable auth setup. ### 20. Fusion Auth Is Awesome **Rating:** 5.0/5.0 stars **Reviewed by:** Satyam G. | Programmer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 27, 2025 **What do you like best about FusionAuth?** I like the fact it can be integrated with any codebase. I had created my sso completely open source. Its secure when you create sso it makes the cookie http only this way only your backend server can read it **What do you dislike about FusionAuth?** Even they provide customize theme for enterprise plan but there should be more preinstall ui the current one is just two tiny small boxes **What problems is FusionAuth solving and how is that benefiting you?** Fusion auth handles authentication across platforms and website that has different subdomain but same domin I've tried ### 21. Fusionauth is budget friendly option for providing SSO to your products **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Entertainment | Mid-Market (51-1000 emp.) **Reviewed Date:** May 30, 2025 **What do you like best about FusionAuth?** - Easier integration with third parties (google, social logins etc) - Newer login options (webauthen) - No code solution for login/signup and emails - Terraform provider to maintain configuration across different env (dev, staging, prod) **What do you dislike about FusionAuth?** - Optional state from frontend doesn't get persisted between MFA - State doesn't go through transactional webhooks **What problems is FusionAuth solving and how is that benefiting you?** We're providing SSO to our users for around 4 products. Its really easy to integrate across different products, e.g next-auth supports fusionauth out of the box. ### 22. Auth Made Simple **Rating:** 5.0/5.0 stars **Reviewed by:** Kevin T. | Senior Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 29, 2025 **What do you like best about FusionAuth?** Cost is great and handles everything we need. **What do you dislike about FusionAuth?** A lot more config is needed when setting up our applications. It was a little more difficult to get started. **What problems is FusionAuth solving and how is that benefiting you?** Fusion Auth is helping us with our centralized auth solution ### 23. Good Auth for security noobs **Rating:** 4.0/5.0 stars **Reviewed by:** Wiktor M. | Student informatyki, Small-Business (50 or fewer emp.) **Reviewed Date:** April 28, 2025 **What do you like best about FusionAuth?** Hi! I'm a CS Student that tried FusionAuth for the first time. It was fairly easy to use and implement in web apps. It's very well documented **What do you dislike about FusionAuth?** Haven't stumbled on any issues for now :) **What problems is FusionAuth solving and how is that benefiting you?** I don't need to write JWT or any other auth solutions by hand whics is a blessing ### 24. Great team to work with **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** May 29, 2025 **What do you like best about FusionAuth?** We've found FusionAuth to be a great partner. When we were evaluating different products to use for our Authentication stack, we compared FusionAuth with another much larger competitor. We elected to pick FusionAuth because we felt that they would be a better partner and would be more responsive to our issues. We definitely made the right decision in this case. They're very easy to work with, very transparent and very responsive. Their support is top notch. **What do you dislike about FusionAuth?** Nothing major. Would be nice if they were able to deliver feature requests more quickly, but that's to be expected. **What problems is FusionAuth solving and how is that benefiting you?** We partnered with FusionAuth to deliver a well-supported authentication platform that supported SAML and SCIM. ### 25. Reliable Product **Rating:** 5.0/5.0 stars **Reviewed by:** Mayuran S. | Director of Engineering, Mid-Market (51-1000 emp.) **Reviewed Date:** March 25, 2025 **What do you like best about FusionAuth?** Ease of integration and implementation was the primary reason to move forward with FusionAuth as our vendor. They are extremely communicative with any downtime and have only 1 incident that affected our integration since we integrated FusionAuth in Oct 2023. **What do you dislike about FusionAuth?** Easier access to uptime such as a status page would be appreciated **What problems is FusionAuth solving and how is that benefiting you?** Offboarding CIAM was the primary focus and introducing MFA needed for our cloud security needs. ### 26. A highly customizable authentication provider **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** April 07, 2025 **What do you like best about FusionAuth?** With FusionAuth it becomes easy to manage the authentication of its applications. One of the biggest advantages of Fusionauth that I appreciated is its API interface which allows to build an overlay when Fusionauth does not make accessible to certain functionalities while maintaining Fusionauth as the authentication core. **What do you dislike about FusionAuth?** Currently, it is not yet possible to manage one-click migrations between different instances or environments. The only possible solution is to write scripts that can apply changes between different environments; this works but could be made even easier if fusionauth allowed one-click migrations. **What problems is FusionAuth solving and how is that benefiting you?** - User management - Authentication - Authorization ### 27. Excellent product and great resources are available **Rating:** 5.0/5.0 stars **Reviewed by:** Scott F. | CEO, CTO, CFO, CMO, CSO, Small-Business (50 or fewer emp.) **Reviewed Date:** September 19, 2024 **What do you like best about FusionAuth?** Logically it makes sense. They also provide SDKs for frameworks like Angular. Their blog posts, AI Bot are all useful resources for figuring out OAuth and integrating their products. And, they continually improve these resources. **What do you dislike about FusionAuth?** The Angular SDK appears to prevent using FusionAuth in a way that seems that is supported by other OAuth compliant servers; e.g. OAuth. Specifically, for additional security, it seems as if the Angular SDK doesn't allow you to have the Authentication server (self-hosted or FusionAuth Cloud) deployed to the cloud and yet use it for local development. It seems like this should be allowed because of other OAuth servers support it and there are other mechanisms to prevent the CORS issues other than the headers the Angular SDK uses. **What problems is FusionAuth solving and how is that benefiting you?** It's allowing me full control using a very capable Authentication Server for free. I host it in Digital Ocean via a Docker container for about $15/mo which is great. And, while learning about OAuth, I was able to explore the various GET and POST requests with JWT to explore the OAuth specification. **Official Response from Brad McCarty:** > Hey Scott! Thanks for taking the time to share your thoughts. I chatted with our devrel folks and they had some insight for me to pass along. First, it's worth noting that this isn't really a CORS issue, but rather an issue with how FusionAuth uses cookies While you can use localhost, it probably takes more setup than is ideal. We have a [caution] block in this section of our docs that explains a bit more. Always happy to chat further. And of course the Community forums might have folks who have run into the same issue, but have found a creative way to solve it. ### 28. AuthX made simple **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** October 17, 2024 **What do you like best about FusionAuth?** The community editon helped us to easily implement a powerful AuthX for our services. It also provides an API which makes integration very easy. **What do you dislike about FusionAuth?** The pricing model imposes some ties between the hosting plans and the license plans, for example you cannot use a community or a starter license on a high availability hosting, it has to be a more expensive one. So if a set of basic features suffice for your needs but you want high availability the only option is to self host. **What problems is FusionAuth solving and how is that benefiting you?** It solves all of our authentications and authorization problems :) **Official Response from Brad McCarty:** > Thanks so much for the review. We're always looking at the best ways forward with pricing, and we'll definitely take your feedback into account. ### 29. Easy to use IAM solution **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Transportation/Trucking/Railroad | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2025 **What do you like best about FusionAuth?** FusionAuth is a very friendly for teams that want to quickly setup an Identity Management solution for their products.

Great IDP for Developer **Rating:** 4.5/5.0 stars **Reviewed by:** Mitchell W. | Director Product Strategy, Mid-Market (51-1000 emp.) **Reviewed Date:** October 16, 2024 **What do you like best about FusionAuth?** There are lots of IDPs out there. This one is focused for developers. APIs are at the forefront of their product. Easy to embed in your product. Also, the pricing is tailored to developers versus the big guys. **What do you dislike about FusionAuth?** It is not as well known as the larger players such as Entra or Okta. Their cloud model is not a multi-tenant model. Seems like they host individual systems on vms. **What problems is FusionAuth solving and how is that benefiting you?** We are a SaaS app. We are looking for a platform that can handle identity management for our application **Official Response from Brad McCarty:** > Thanks for the review, Mitchell! I'd love to hear more about your thoughts on multi-tenant. As far as we're concerned, being single-tenant hosted means that you don't have to worry about problems with noisy neighbors, and it helps you avoid potential breaches when someone else causes a problem. ### 42.

Good product with myriad possibilities **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Consumer Services | Mid-Market (51-1000 emp.) **Reviewed Date:** March 25, 2025 **What do you like best about FusionAuth?** FusionAuth is a robust CIAM that offers many features for authenticatication and authorization. The team is helpful and the product is easy to use. **What do you dislike about FusionAuth?** Although there is a lot of documentation, I miss the details and the depth sometimes. I'd also appreciate more video tutorials on more complex subjects and implementations. **What problems is FusionAuth solving and how is that benefiting you?** Improving our SSO solution. ### 50. A fantastic CIAM service which feels like it was built for developers **Rating:** 5.0/5.0 stars **Reviewed by:** Matthew C. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 04, 2024 **What do you like best about FusionAuth?** - Once you have done the initial configuration in your code base (setting the callback routes, handling the grant in your controller etc.) , everything else can be configured in the FusionAuth Dashboard. For example, adding new IdPs, themeing, hiding/showing fields etc. can all be done in a intuitive UI without needing to redploy your application. - The FusionAuth Dashboard itself is (to me) much more straightforward and locigical compared with Auth0, which I have used in the past. They have some great features in there like "Lambdas" which trigger when certain actions happen, making it easy to hook into the signin flow dependant on which IdP you are using. It is very customizable, but also has some great default out-of-box settings. - Pretty active developer support through a maintained GitHub Issues page, which feels like they are working alongside developers to build a product that their users want. - All the support and advice during the kick-off meetings was very helpful. Sometimes those meetings can be sales-heavy, but we had a lot of engineers on the call offering great insights and advice. **What do you dislike about FusionAuth?** - Whilst the documentation is pretty good, getting started is a little overwheleming, mainly because of all the different ways that you can configure FusionAuth (self-install or cloud-based). A more streamlined "Getting Started" guide for SaaS based products using cloud-based instances would help to get up-to-speed quicker. I feel like the documentation is all there, but it is sometimes hard to find what you need due to the way it is organized. - I love that you can really customize the theme of all the pages and emails. However the theme template engine that they use is a little bit cumbersome. Once you get the hang of it, it does the job fine, but there is a bit of trial-and-error required to get started with it. **What problems is FusionAuth solving and how is that benefiting you?** - Enables us to quickly add support to any IdP that we need - Comes with the ability to support SCIM which helps us to provide an enterprise login solution for our larger customers - Gives us access to more advanced login features such passwordless login, biometric login, more MFA options, password breach checks etc. ## FusionAuth Discussions - [Is FusionAuth free?](https://www.g2.com/discussions/is-fusionauth-free) - 1 comment - [View FusionAuth pricing details and edition comparison](https://www.g2.com/products/fusionauth/reviews?page=2§ion=pricing&secure%5Bexpires_at%5D=2026-07-01+22%3A22%3A02+-0500&secure%5Bsession_id%5D=d60ca157-9fc4-418e-8e3f-69aa4282175c&secure%5Btoken%5D=c0d3e3253aa574fdf919150455866a899aed42404a4e7101d86bf2886138c96e&format=llm_user) ## FusionAuth Integrations - [Azure Cloud Services](https://www.g2.com/products/azure-cloud-services/reviews) - [Google Workspace](https://www.g2.com/products/google-workspace/reviews) - [Laravel](https://www.g2.com/products/laravel/reviews) - [Oracle Database](https://www.g2.com/products/oracle-database/reviews) - [React Native](https://www.g2.com/products/react-native/reviews) - [WordPress.org](https://www.g2.com/products/wordpress-org/reviews) ## FusionAuth Features **Authentication Options** - Authentication User experience - Supports Required Authentication systems - Multi-Factor Authentication - Supports Required Authentication Methods/Protocols - Federation/SAML support (idp) - Federation/SAML support (sp) **User on/off Boarding** - Self Service Access requests - Smart/Automated Provisioning - Role Management - Policy Management - Access Termination - Approval Workflows **Authentication type** - SMS-Based - Voice-Based Telephony - Email-Based - Hardware Token-Based - Software Token - Biometric Factor - Mobile-Push - Risk-Based Authentication **Integration** - Uses Open Standards - Mobile SDK - Workforce Authentication - Customer Authentication **Administration** - Bi-Directional Identity Synchronization - Policy Management - Cloud Directory - Application Integrations **Functionality** - Active Directory integration - LDAP integration - Hacker dictionary - Custom blacklist dictionary **Functionality** - Self-registration and self-service - Authentication - Scalability - Consent and preference management - Social login - Customer data linking **Functionality** - FIDO2-compliant - Works with hardware security keys - Multiple authentication methods - Offline or no-phone solution **Functionality** - User provisioning - Password manager - Single Sign-on - Enforces policies - Authentication - Multi-factor authentication **Access Control Types** - Endpoint access - Local Access - Remote Access - Partner Access - Supports BYOD users **User Maintenance** - Self Service Password Reset - Bulk Changes - Bi-directional Identity Synchronization **Functionality** - Multi-Device Sync - Backup **Administration** - Encryption - Audit Trails - Regulatory Compliance **Administration** - Password synchronization - Centralized management - Group policy complexity controls - Multiple policies - Multi-lingual ** Type** - On-premises solution - Cloud-solution **AI Authentication Risk Management - Customer Identity and Access Management (CIAM)** - Adaptive MFA - Anomaly Detection - Fraudulent Login Detection - Adaptive Authentication Policies - Risk-Based Authentication **Administration** - Ease of installation on server - Password Policy Enforcement - Administration Console - Ease of connecting applications - Self Service Password Administration **Governance** - Identifies and Alerts for Threats - Compliance Audits ** Reporting** - Tracking - Reporting - Access & Permission Change Reporting - Compliance & Audit Trail Export **Implementation** - Easy Setup - Mobile SDK - Web SDK **Platform** - Multiple Operating system support - Multi-Domain Support - Cross Browser support - Fail over protection - Reporting - Auditing - Third Party Web Services support **Administration** - Reporting - Ease of set up for target systems - APIs **Authentication & Authorization - Identity and Access Management (IAM)** - Adaptive & Contextual Access Control **Administration & Governance - Identity and Access Management (IAM)** - Identity Lifecycle Management - Self‑Service Account Management ## Top FusionAuth Alternatives - [Auth0](https://www.g2.com/products/auth0/reviews) - 4.3/5.0 (264 reviews) - [Frontegg](https://www.g2.com/products/frontegg/reviews) - 4.8/5.0 (362 reviews) - [OneLogin](https://www.g2.com/products/onelogin/reviews) - 4.4/5.0 (272 reviews)
