Effortlessly Secure and Easy to Implement CIAM
Reviewed on Apr 09, 2026
Review provided by G2
What do you like best about the product?
I mostly like the ease of use and the support from the implementation team. It's great that we can reach out through Slack. FusionAuth is reliable, stable, and we've not experienced any problems so far. The initial setup was really easy, with many ways of importing our existing user base with barely any impact.
What do you dislike about the product?
I cant think of any
What problems is the product solving and how is that benefiting you?
FusionAuth provides secure customer identity access management without requiring us to develop our own solution. It's easy to use, reliable, and stable. The support team is accessible through Slack, and the setup was easy with minimal impact when importing existing users.

Flexible, Reliable, and Well-Documented Authentication Solution
Reviewed on Apr 08, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
FusionAuth supports diverse user authentications across our platform, including multi-tenant infrastructure, self-sign ups, third-party integrations, and customizable policies, which solves various customer needs.

Powerful, Flexible Authentication with Effortless Setup and a Great UI
Reviewed on Mar 23, 2026
Review provided by G2
What do you like best about the product?
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).
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
FusionAuth provides me with a clean, trustworthy, and efficient way to meet my authentication and authorization needs. Just as importantly, they have a team of real people—engineers, architects, and integration experts—who help ensure you get the most out of their offering. We not only addressed this need, but also discovered additional areas where FusionAuth could add value and reduce our reliance on bespoke solutions within our own offering.
