FusionAuth Reviews & Product Details

The flexibility of the offering, paired with its power, feels unmatched in the authentication industry right now. With both self-hosted and cloud-managed options—and clear migration pathways between the two—it stays extremely cost-effective for software businesses of any size. Setup is a single line for self-hosted deployments, and the UI/UX web application is incredibly easy to use for managing your instance(s). Review collected by and hosted on G2.com.

The cost of the self-hosted license is a bit steep, even though it’s still very competitive. FusionAuth would benefit from lowering that barrier to entry so more customers have the chance to succeed with FusionAuth powering their authentication needs. In turn, that could help drive additional sales as those customers grow their businesses, including eventual moves like cloud migrations from self-hosted. Review collected by and hosted on G2.com.

Supports self-hosting. The documentation is solid for setup and for automating workflows using APIs. Support has been responsive in my experience. It also covers multiple scenarios without compromises, including multi-tenancy, user and group management, federation, and M2M tokens. Finally, the pricing model is clear and attractive.

There’s a lack of a built-in tenant discovery flow on the login screen. Review collected by and hosted on G2.com.

The most valuable part of the software is the shared folders themselves (that was the real game changer) - You provide the Servicedesk Team with what they need to know, the Systems Team gets all that AND more, and NO ONE is putting their login credentials into Slack or trying to keep a Google Sheet that has three people with EDIT ACCESS as a way to avoid password sharing. Credentials remain encrypted and no one will ever have to look at your password unless you want to show them. Review collected by and hosted on G2.com.

Autofill shows up in almost EVERY INPUT FIELD on EVERY PAGE, regardless of whether it is a password field or not. And there is NO WAY to quickly disable Autofill for a particular site without going through the Settings options. That becomes old FAST. Switching from a Personal Account to a Business Account is CLUMSY - I am unable to View both Accounts at the same time, I just bounce back and forth, which BREAKS Autofill HALF THE TIME. Petty One: Save Prompt comes up for 2-3 pages AFTER you have already DISMISSED it ONCE, one reminder is ENOUGH. Also, no SubFolder Structure, which makes Organizing a LARGE Vault much more annoying than it should be. Review collected by and hosted on G2.com.

Honestly I think the biggest benefit is that I don’t have to remember a million different passwords anymore and since we use it for work and it handles everything from generates strong passwords whenever I want one and stores them automatically and populates passwords when I log in somewhere. The password sharing feature has been especially convenient because our whole team needs to get into some accounts and before we would just send them over slack which likely isn’t ideal.

They had me make a master password which made sense but then they wanted me to make another password as well? And I wasn’t entirely sure if these two passwords were supposed to be the same or if they should be different as the wording of that section wasn’t very clear. And sometimes it even comes up randomly on forms fields that don’t require it, and I have to navigate past it to complete things normally. Review collected by and hosted on G2.com.

I really appreciate the high degree of flexibility in FusionAuth's configuration, which has been incredibly handy. The documentation is another standout feature; my team often solves needs for our product and customers using it without having to reach out for support. The service has been reliable, satisfying all the various use cases we've tested so far. I also like how seamlessly it integrates with our SaaS tool through the API, making the overall experience quite smooth. Review collected by and hosted on G2.com.

When migrating users with the B2C connector, if a user did not remember their password, the account would not transition properly. They would try to select 'forgot password', but hadn't actually converted their account successfully to FusionAuth yet. Maybe making it more prominent on the options for handling when users don't remember their passwords while transitioning from the old provider would be helpful.

I like how easy it was to get FusionAuth up and running and having a full login and user management system in place. The documentation was clear and helpful and I could plug it into our web app with little fuss. The dashboard is simple and gives me quick access to users roles and settings without having to dive into the database manually. I also appreciate the support for multiple authentication methods so our users can sign in in ways that fit them. Review collected by and hosted on G2.com.

The theme customization felt limited and took extra time to bend it to look like our brand. Some of the more advanced workflows were not intuitive and I had to piece them together by trial and error. Review collected by and hosted on G2.com.

What I like most about FusionAuth is its flexibility and ease of integration. It provides strong authentication features while still being developer-friendly and customizable to different use cases. Review collected by and hosted on G2.com.

At times, the configuration and setup for more advanced, out of the box scenarios can be a bit involved, but overall it’s manageable once you’re familiar with the platform.

Also reporting could be more dynamic Review collected by and hosted on G2.com.

What I like most about FusionAuth is its flexibility. It’s really intuitive to set up. I’m not a full-time developer, but I’m pretty sure I can configure logins, SSO, and integrations in a much easier way without spending days reading documentation. Fine-grained customization allowed me to form the login experience around my company’s brand perfectly, a process that other avenues made extremely cumbersome. It feels like the control is with me and not that I require external consultants. Review collected by and hosted on G2.com.

The main drawback is the learning curve once you want to go beyond the basics. Some of the more advanced workflows, such as complex triggers or esoteric identity provider integrations, take a bit of trial and error. Also, while being more approachably priced than Auth0, the add-ons can add up if you’re not careful. Review collected by and hosted on G2.com.

API documentation and extensibility are strong, and I’ve had great, professional contact with Engineering, with fast responses. Pricing is competitive and transparent, and there’s a calculator available for everyone without needing to contact Sales first. Compared with competitors, it also delivers great performance in batch operations, such as batch importing users. The UI could be a bit more self-descriptive, though.

I don’t think there’s anything like this yet – except, maybe, a few confusing UIs. Review collected by and hosted on G2.com.

I use FusionAuth to handle customer identity management across our product suite, and it has been valuable due to its affordability at our scale compared to Auth0 or Okta. I really appreciate that the platform is fully API-driven, which allows us to automate client and user onboarding, saving us time. The direct communication with FusionAuth solution architects via a private Slack channel was crucial in meeting tight implementation deadlines. With FusionAuth, we can get faster results by going directly to the source, unlike Okta and Entra where we relied on the general developer community. Moreover, the initial setup was relatively straightforward, and we were able to purchase FusionAuth for less money while obtaining more functionality than we had with our Okta subscription.

We ran into some challenges with mixing single tenant applications and multi-tenant applications but we were able to work around it. Review collected by and hosted on G2.com.
