Authentication and Single Sign-On (SSO)
Single sign-on (SSO) is a feature which enables users to authenticate just once and then access multiple websites without the need to enter logon credentials again for each site.
By default, Sitefinity CMS uses claims-based identity. In a claims-based scenario, the identity of the user is authenticated by Security Token Service (STS). The STS issues tokens that contain the claims, which the user makes about their identity. Claims can contain the user identity as well as roles and permissions.
Sitefinity CMS supports two authenticals models:
- Forms authentication
- Claims-based authentication
