Microsoft Azure SSO is a centralized identity platform that authenticates users once to provide access to multiple applications. It supports various authentication standards, including SAML 2.0, OpenID Connect, OAuth 2.0, and header-based and password-based SSO, with a gallery of pre-integrated applications to simplify setup. The service can enforce multi-factor authentication and conditional access policies based on user, device, location, and risk context. Administrators can assign application access to users and groups, customize tokens and claims, and monitor sign-in activity through logging and reporting, while end-users can access their assigned applications through a central My Apps portal.
