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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Very easy to set up, and get running. We have a simple use case that most other products over-engineered.

Still very good Review collected by and hosted on G2.com.

Nothing negative comes to mind. The setup was great, and support was very helpful getting us integrated Review collected by and hosted on G2.com.

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.

All good. Still not found any issues in FusionAuth Review collected by and hosted on G2.com.

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! Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Lots of features especially handling configuring things based on applications, entities and tenants Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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?! Review collected by and hosted on G2.com.

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 ;-) Review collected by and hosted on G2.com.
