Single sign-on (SSO) allows a user to log in once and gain access to multiple independent systems without re-authenticating, saving time. SAML is a protocol that implements SSO in enterprises by defining identity providers, service providers, and the transfer of authentication data between the two using XML messages. Implementing SSO involves configuring servers as identity providers or service providers and exchanging metadata between the two to enable single sign-on access across systems.
