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

Show More Response from Story Tweedie-Yates of FusionAuth [Editedit](https://www.g2.com/survey_responses/fusionauth-review-10980724/official_response/edit) 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.

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. What do you dislike 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. Review collected by and hosted on G2.com. 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.
