Is SSO the Same as SAML?

The document explains that SSO is the user experience of logging in once, while SAML is a protocol that enables it, detailing IdP/SP roles, SAML assertions, and why enterprises rely on SAML 2.0. It offers practical implementation and security guidance—use proven toolkits, support SCIM for directory sync, manage multiple IdPs and certificates, maintain an admin bypass, enforce MFA, and separate authentication (SAML) from authorization (OAuth/RBAC).
