Single Sign-On (SSO) enables users to authenticate once and receive authorizations for multiple services across the network. What does SSO enable?

• A. Authenticate multiple times for different services
• B. Store credentials for offline use
• C. Authenticate once and receive authorizations for multiple services
• D. Use a password manager to log in

Answer: (C)

Single Sign-On lets you authenticate once to a central identity provider, and that proof is trusted by multiple services across the network. After your initial sign-in, the provider issues a token or assertion that other services accept, so you can access those resources without logging in again while the token remains valid. This improves user experience by eliminating repeated logins and reduces password fatigue, since you don’t need to enter credentials for each service. It does rely on strong protection around the central identity provider and well-managed, short-lived tokens to prevent broader access if a token or the IdP is compromised. The other options describe re-entering credentials for each service, storing credentials offline, or using a password manager, none of which capture the seamless, centralized authentication that SSO provides.
