What is SSO ?

Single sign-on (SSO) is an authentication method that enables users to access multiple applications with  one-click login  and one set of credentials. For example, after users log in to your org, they can automatically access all apps from the App Launcher. When you set up SSO, you configure one system to trust another to authenticate users , eliminating users' need to log in to each system separately. The system that authenticates users is called an Identity provider. The system that trusts the identity provider for authentication is called the Service provider.

SAML allows exchanging of information between Service Provider and Identity provider, SAML is integration between SP and IDP. When a user tries to log in, your identity provider sends SAML assertions containing facts about the user to Identity Provider. Identity Provider receives the assertion, validates it against your Identity Provider configuration, and allows the user to access your org.
