Single Sign-On / Federation (SSO/Federation)

Federation (Different Domains)

Federation is a trust relationship between two systems or organizations.

It defines where user credentials are stored and how those credentials can be used for authentication without exposing them to a third party.

Single Sign-On (Multiple Applications in One Domain)

Single sign-on allows users to authenticate and access different applications in the same domain by signing in once through the identity provider and establishing a session.

It can also be used to provide single logout.
