Strong API Docs, Fast Engineering Support, and Great Extensibility
Reviewed on Apr 22, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
I don’t think there’s anything like this yet – except, maybe, a few confusing UIs.
What problems is the product solving and how is that benefiting you?
We’re currently in the POC stage, so there isn’t much to report yet. Our goal is to address the challenge of handling user authentication securely, including MFA and social login.

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.
