EA Elizabeth A. CEO Small-Business (50 or fewer emp.) 6/17/2025 "FusionAuth is a one stop gateway that simplified our workflow and boosted security." 5/5 What do you like best about FusionAuth? FusionAuth's ability to concentrate everything I need into one, simple platform appeals most to me. FusionAuth provides one tidy dashboard where all of my professional apps sit; I no longer have to go through bookmarks or balance several logins to identify the correct tools. Not only tools, the single sign-on and multi-factor authentication are daily lifesaver. It feels like my entire workflow got a speed boost and a security upgrade all at once. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? The multi-step login, especially with MFA, can feel a bit tedious—there have been moments where codes don’t sync or I need to retry a few times. Also, switching devices (especially phones) messes with the setup and isn't as seamless as it should be. And compared to a few competitors like Okta or Auth0, FusionAuth's UI feels a little more functional than refined. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? FusionAuth solved one of the biggest daily headaches: managing access to seven different tools I rely on throughout the day. Instead of logging into each one separately, I just sign in once and I’m good to go. It has reduced password fatigue significantly, improved our team’s compliance efforts, and made onboarding and offboarding users practically effortless thanks to automated provisioning. I’ve used Okta in the past, and while it’s solid, I’ve found FusionAuth’s developer-first approach and pricing far more aligned with our team’s real-world needs.

DH DeeAnna H. Chief Marketing Officer Small-Business (50 or fewer emp.) 6/15/2025 "FusionAuth greatly helps with identity management for hybrid environments" 4.5/5 What do you like best about FusionAuth? FusionAuth's seamless interaction with on-site and cloud-based solutions is what most appeals about it. It has been quite simple to set up roles, control user access, and apply SSO throughout several SaaS systems. It also has strong API support and seamlessly incorporate into our CI/CD processes which have greatly delighted me. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? One drawback I have observed is that, like Entra ID P2, some of the sophisticated security and identity governance tools call for premium licensing. Furthermore, especially in troubleshooting, the on-site synchronizing mechanism might be more open and user-friendly. Although FusionAuth is quite flexible, mass actions usually call for scripting knowledge—PowerShell in other platforms or custom CLI tools here—which might not be perfect for non-technical teams. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? FusionAuth has greatly simplified user ID management for hybrid systems. Managing access for remote and on-site users used to be a disjointed mix of systems, but with FusionAuth we handle all centrally—policies, roles, device access, even audit trails. Especially in relation to legacy AD systems, the speed at which we can onboard or deprovision users has saved our team innumerable hours. Review collected by and hosted on G2.com.

VP of Sales Mid-Market (51-1000 emp.) 6/11/2025 "FusionAuth is a very developer friendly identity solution that works without any issue" 5/5 What do you like best about FusionAuth? I love how FusionAuth lets me own my data and run everything on-premise, which gives me a level of control that SaaS solutions like Auth0 just don’t offer. Setting it up was smooth and the API-first design and thorough documentation also meant I didn’t have to guess or dig through forums. It’s refreshing to see a platform that doesn’t get in my way when I want to tweak things deeply, even with custom themes and tenant-specific configurations. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? The UI is functional but not exactly delightful—it’s very utilitarian. Also, multi-tenancy is great, but it can feel a bit over-complicated at times, especially when managing separate branding per tenant. Finally, while the documentation is robust, some edge-case behaviors around SSO and JWT token handling could be better clarified. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? FusionAuth solved a major headache for me—managing authentication across multiple apps without giving up control or paying a fortune. I’ve used Auth0 before, but the free tier ran out fast and the lock-in was a real concern. With FusionAuth, I can run everything locally, customize login flows, and even add social login without needing a PhD in identity protocols. FusionAuth also saved me much time and resources by eliminating the need to roll my own auth while still letting me build exactly what I want. Review collected by and hosted on G2.com.

Chief Technology Officer Small-Business (50 or fewer emp.) 6/9/2025 "FusionAuth is secure and has hassle free authentication and is also very flexible" 4/5 What do you like best about FusionAuth? What I like most about FusionAuth is how incredibly easy it is to integrate into our applications, especially when working under tight deadlines. Its adaptability with social logins changes everything. I have used it for minimal setup single sign-on and two factor authentication. The Universal Login function also made our sign-in process flawless on several platforms. It’s one of the few tools I’ve worked with that feels like it was built with developers in mind. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? The only real drawback I’ve noticed is the pricing as your usage scales — it can become a concern for startups or smaller teams. While support is generally helpful, having more instant, real-time assistance for critical production issues would be great. FusionAuth occasionally lacks the brand-based confidence found inAuth0 or Okta, which might concern some stakeholders. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? FusionAuth saved weeks of laborious effort for our SaaS platform serving numerous tenants, which needed a safe authentication system. We had everything functioning in a few days instead of creating login flows and user management from nothing. It has drastically cut development time but still let us live in a trustworthy and safe environment. Unlike some other options like AWS Cognito, which felt overly complex and clunky, FusionAuth felt intuitive, developer-focused, and ready to scale with us. Review collected by and hosted on G2.com.

IAM Program Manager Information Technology and Services Small-Business (50 or fewer emp.) 8/20/2025 "Finally, our team can build features, not just endlessly manage user logins" 4.5/5 What do you like best about FusionAuth? What we truly like is that it is quite seamless to utilise several separate client environments with only a single FusionAuth instance. The flexibility of the theming of our online onboarding process of new B2B customers has allowed us to add a branded login experience without any glitches. We also found the custom data fields so helpful in assigning specific fields of data to user profiles, in order to drive some of our internal analytics. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? The configuration settings that are not used often, at times, are a little less transparent to navigate the console. We also would have liked to see an easier way to export/import whole application setups between our development and production servers. There was also a steep learning curve to using some of the advanced webhook event triggers, although this got easier as time went on. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? We found it very difficult to offer different branded identity experiences to each of our B2B clients, and then have a single user database. Previously to FusionAuth it could take weeks of custom development to implement a new customer inviting them to use a customized portal into their company and managing their user account. Once, it takes weeks to spin up a new client tenant with its own branding, and user roles, now it only takes a matter of hours. It has turned onboarding client workflows into a fast repeatable procedure. Review collected by and hosted on G2.com.

Director of DevOps Mid-Market (51-1000 emp.) 2/22/2024 "FusionAuth has been a great solution for replacing our original provider." 5/5 What do you like best about FusionAuth? FusionAuth has been very easy to integrate with, supports all of our requirements, including a vendor supported terraform module, and the admin/management UI is easy to work with and navigate. Developers were able to adapt easily to the new provider and new features have been very easy to implement. Their customer support has been fabulous when we needed them. We utilize FusionAuth for all systems in all environments. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? There is one nagging bug that we would love fixed that happens rarely but it's a difficult fix I guess and still has not been released. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? FusionAuth is our authorization system for our applications. It helps us meet our compliance requirements and requires no real management from us. Our customers like it because of the seamless SSO support and MFA capabilities. It's available as a SaaS product which we use for most of our applications. For a very few specialized deployments which frown upon using a cloud offering, we can deploy FusionAuth in a container and meet those requirements. Review collected by and hosted on G2.com.

What really won me over with FusionAuth is how naturally it fits into our Microsoft-heavy environment. Setting up SSO across Outlook, Teams, and SharePoint felt like flipping one big switch — suddenly, people weren’t forgetting passwords or pinging IT for access issues every other day. Conditional Access is one of those features I didn’t know I needed until I had it; I can allow access based on location or device, which has been huge for our remote team. Also, being able to roll out MFA using the Microsoft Authenticator app made our compliance team very happy without annoying our staff. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? The initial setup almost broke me. Trying to integrate FusionAuth with our older on-prem Active Directory was like stitching two universes together, and don’t get me started on SAML — it feels half-baked compared to Okta’s clean implementation. Also, some of the policies become a labyrinth over time; one misstep and you’re locked out of your own admin portal wondering what went wrong. Review collected by and hosted on G2.com. What problems is FusionAuth solving and how is that benefiting you? Before FusionAuth, managing user access felt like whack-a-mole — new hires, password resets, inconsistent MFA rules across tools. Now, I can onboard a new employee in minutes: create the user, drop them into the right group, and they’re good to go with full device-level security via BitLocker and conditional access.

FusionAuth has been a bit of a game-changer for us—not in the flashy, overhyped way some tools promise to be, but in a grounded, reliable kind of way. What I’ve come to appreciate is how it quietly takes care of the identity chaos that used to haunt our stack. Setting up OAuth2 and SSO was surprisingly smooth; I had our core app talking to FusionAuth in under ten minutes, which honestly shocked me after wrestling with tools like Keycloak in the past. Review collected by and hosted on G2.com. What do you dislike about FusionAuth? Multi-tenant setups took some brainpower and trial-and-error, especially since our team doesn’t live and breathe IAM. The reporting side also feels undercooked—it gives you the basics, but if you’re used to slicing and dicing access logs like you can with tools like Okta, you’ll feel a bit boxed in. And while support is helpful, I’ve had moments where I wished for a bit more than just a link to the docs when tackling edge-case scenarios. Review collected by and hosted on G2.com.

We no longer have five different half-baked login flows duct-taped together, and managing access across environments doesn’t require a prayer and a late night. The fact that we can host it ourselves gives us peace of mind—especially in Fintech, where compliance paranoia is kind of the norm. Compared to Auth0, which got expensive fast, and rolling our own solution (which was a nightmare I’d rather not revisit), FusionAuth hits that sweet spot: flexible enough to grow with us, stable enough to trust, and just opinionated enough to keep us out of trouble.
