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.

Unmatched Ease and Flexibility for Identity Management
Reviewed on Mar 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
Reviewed on Mar 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.

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.

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.
