Single Sign-On
SSOAuthentication scheme that allows users to access multiple applications with one set of login credentials.
What is Single Sign-On?
Single sign-on improves user experience by eliminating the need to remember multiple passwords while reducing password fatigue that leads to weak credential practices. From a security perspective, SSO centralizes authentication through a trusted identity provider, enabling consistent policy enforcement, better visibility, and easier credential management.
In Microsoft 365
Azure AD/Entra ID serves as the identity provider for SSO across Microsoft 365 applications and thousands of SaaS applications in the Azure AD app gallery. SAML, OpenID Connect, and WS-Federation protocols enable SSO with both cloud and on-premises applications.
