Microsoft Security, Compliance, and Identity Fundamentals SC-900 Practice Question

Single sign-on (SSO) is a fundamental Microsoft Entra ID feature that creates one user session after the initial sign-in. The resulting token is accepted by Microsoft 365, Azure, and integrated third-party SaaS applications, so the user is not prompted for credentials again. Conditional Access applies policies to each sign-in attempt, multifactor authentication adds a second verification factor, and Privileged Identity Management controls the lifecycle of elevated roles; none of these provide the seamless reuse of the same credentials across multiple apps that SSO delivers.
