FusionAuth FAQ

How does FusionAuth support customer identity and access management?

FusionAuth provides a complete authentication infrastructure that includes registration, login, multi-factor authentication (MFA), and single sign-on (SSO). It allows organizations to manage customer identities and authentication processes, with the option to self-host the entire system.

Which teams benefit most from using FusionAuth?

Teams that require full-featured authentication infrastructure and prefer to maintain control over their data by self-hosting will find FusionAuth suitable. It is designed for organizations that need robust identity management capabilities on their own servers.

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?

Self-hosting FusionAuth provides data control but introduces complexity in deployment and management. Users may also experience a learning curve to fully utilize its features, and the enterprise-level plans can be expensive.

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.
