When integrating Salesforce with an enterprise identity provider (IdP), you must choose between SAML and OAuth based on whether users need seamless login access or secure data sharing. SAML enables single sign-on where users authenticate once and access multiple applications without re-entering credentials. OAuth 2.0 enables secure data sharing between applications, allowing one app to access data from another on behalf of a user.

Core information
  • SAML is the protocol that enables single sign-on (SSO), allowing users to move seamlessly between Salesforce and other applications without logging in repeatedly.
More details and nuances
  • After a My Domain login URL or site URL change, SAML SSO authentication stops working until the IdP configuration is updated with new authentication values including Assertion Consumer Service (ACS) URL, Logout URL, and Entity ID.
