CompTIA Network+ N10-009 Practice Question

Single sign-on (SSO) allows a user to log in with a single ID and password to any of several related, yet independent, software systems. This is correct because SSO enables convenient access by using one set of login credentials, enhancing both user experience and security by reducing the number of credentials users must manage and potentially expose. Other answers are incorrect as they describe processes not aligned with the fundamental concept of SSO: Automatic log-off involves the system terminating sessions after a period of inactivity. Two-factor authentication involves a two-step verification process, typically requiring something the user knows and something the user has, which is more of a security measure for authentication rather than a facilitation of a single access point. Lastly, encrypted passwords refer to the security practice of storing user credentials in a non-plain text format, which is unrelated to how SSO functions for user authentication across systems.
