What is the primary benefit of single sign-on (SSO) in Microsoft Entra ID?
A.Users never need passwords at all
SSO reduces sign-ins but doesn't remove authentication itself.
B.Users authenticate once and can access multiple applications without re-entering credentials
One authentication → many app sessions. Correct.
C.All applications share the same stored password
Apps never share passwords — SSO brokers tokens, not credentials.
D.It eliminates the need for authorization checks
Authorization still applies per application and role.
Why this answer
SSO lets one identity and one sign-in session unlock many apps — fewer credentials to manage, better UX, central revocation. Each app still performs its own authorization; SSO is about authentication, not shared passwords.
