Microsoft Azure Fundamentals AZ-900 Practice Question

Single sign-on lets users authenticate once and then access multiple applications and resources without being prompted again, delivering a seamless user experience.

Multi-factor authentication (MFA) adds an extra verification factor to strengthen security, but using MFA alone does not automatically give users access to other applications after they sign in.

Passwordless authentication replaces the password with a strong credential (for example, Microsoft Authenticator or a FIDO2 key) but still requires a sign-in to each application unless SSO is also configured.

Conditional Access evaluates signals such as user location, device compliance, and risk to decide whether to allow, block, or require additional authentication. Although Conditional Access policies can include session controls like sign-in frequency, they are not an authentication method that automatically grants access across multiple apps after a single sign-in.
