Single Sign-On (SSO)
Single Sign-On (SSO) is an authentication mechanism that allows users to log in once and gain access to multiple related systems and applications without re-entering credentials. SSO improves user experience (fewer passwords to remember) and can improve security (one strong authentication event replaces multiple weak ones) when properly implemented.
SSO works through identity federation protocols like SAML, OAuth, and OpenID Connect. When combined with MFA, SSO provides strong authentication across your application portfolio while reducing password fatigue and the associated security risks of password reuse.
Why It Matters
SSO supports CMMC authentication requirements by providing a centralized, consistent authentication experience. When combined with MFA, SSO reduces the number of credential sets users manage while maintaining strong security.
