Strong API Docs, Fast Engineering Support, and Great Extensibility

  • April 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

  • April 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

  • April 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.

Effective SSO Solution with Competitive Pricing

  • Review provided by G2

What do you like best about the product?
I appreciate the simplicity of FusionAuth, which makes it easier to use. The great support provided is definitely a plus, and I find the pricing to be appealing.

I heard a developer say that he wishes that the redirect to FusionAuth took more query parameters so we could pass more context along.

FusionAuth allows us to integrate our apps to use the same login credentials our clients have, simplifying authentication. I like its simplicity, great support, and pricing.

Powerful, Flexible Authentication with Effortless Setup and a Great UI

  • March 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.

Unmatched Ease and Flexibility for Identity Management

  • March 20, 2026
  • Review provided by G2

What do you like best about the product?
We use FusionAuth as our primary identity system for user authentication and facilitating SSO with larger clients. I love its full-featured identity management with added security, like MFA. It's very easy to implement, offering almost unlimited flexibility for any desired solution. The onboard and pilot team is fantastic, providing invaluable insights on advanced features as we grow. There's no easier identity solution to set up and deploy, and I wouldn't change a thing as we've had zero issues.
What do you dislike about the product?
Nothing. I would not change a thing.
What problems is the product solving and how is that benefiting you?
We use FusionAuth for identity management and SSO, benefiting from its full-featured security and MFA capabilities.

Affordable, API-Driven, and Stellar Support

  • March 18, 2026
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
We ran into some challenges with mixing single tenant applications and multi-tenant applications but we were able to work around it.
What problems is the product solving and how is that benefiting you?
FusionAuth offloads the risk of managing sensitive credentials, is more affordable than alternatives like Okta, and its API-driven nature allows us to automate onboarding. Direct access to solutions architects accelerates problem-solving.

Flexible, Developer-Friendly Authentication with Easy Integration

  • March 18, 2026
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
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
What problems is the product solving and how is that benefiting you?
It takes away the complexity of building and maintaining authentication from scratch. With features like social login and user management handled in one place, it saves time for the team and makes the experience smoother for users.
