SAML: Enterprise Single Sign-On
SAML is older, XML-heavy, and unfashionable — and it still runs enterprise identity, because the corporate world standardized on it a decade before OIDC existed and enterprise software moves slowly. If you build anything sold to businesses, you will meet SAML, and understanding it as "the same federated-login idea as OIDC, different machinery" is what makes it approachable.
