SAML

Learn about the Security Assertion Markup Language (SAML) protocol, which is an open-standard, XML-based framework for authentication and authorization between two entities without a password.

The Security Assertion Markup Language (SAML) protocol is an open-standard, XML-based framework for authentication and authorization between two entities without a password:

• Service provider (SP) agrees to trust the identity provider to authenticate users.
• Identity provider (IdP) authenticates users and provides to service providers an authentication assertion that indicates a user has been authenticated.
