Transparent Cross-Application Access

Whether you have two, five, or 100 applications, the user will never know. A single login is all it takes to let them switch between apps transparently.

Not all users need the same privileges. FusionAuth gives you control over the SSO behavior of your users and the groups they belong to. Customize SSO session durations and revoke access on a per-user basis.

Control user privileges within SSO (groups, sessions).
