Which statement is true about OS security features such as passwords, face ID, or fingerprint?

• A. Security features like passwords, face ID, and fingerprint are used to manage user access.
• B. They are unrelated to user management.
• C. They are used only for device encryption.
• D. They replace the need for an OS user account.

Answer: (A)

Authentication and access control are what these security features handle. Passwords, face ID, and fingerprint verify who you are and then grant access to the operating system, apps, data, and settings. They tie your identity to a user account so each person can have their own personalized environment with appropriate permissions. The goal isn’t just to protect data at rest; it’s to ensure that only authorized users can sign in and use the system. While biometrics can be used to unlock encryption, their primary role is authenticating you to the OS, not replacing the need for a user account.
