FusionAuth FAQ

How does FusionAuth support customer identity and access management?

Which teams benefit most from using FusionAuth?

How does FusionAuth compare to Auth0 for identity management?

FusionAuth offers a comprehensive feature set for identity and authentication, similar to Auth0, but with the distinct advantage of self-hosting options. While Auth0 is a larger platform, FusionAuth allows organizations to keep their authentication infrastructure and data under their direct control.

What kind of trade-offs are involved with self-hosting FusionAuth?

Does FusionAuth include support for Single Sign-On (SSO)?

Yes, FusionAuth provides complete SSO support as part of its authentication infrastructure. This allows users to log in once and gain access to multiple applications without re-authenticating.

How is FusionAuth priced?

FusionAuth is available on a free tier, allowing users to get started without initial cost. For organizations with greater usage requirements or needing more advanced features, paid plans are offered.

Can FusionAuth be deployed on an organization's own servers?

Yes, FusionAuth is designed with self-hosting as a core option, allowing organizations to run the complete authentication infrastructure on their own servers. This provides direct control over identity data and systems.
