Which of the following authentication methods is used to access public areas of a Web site?

Anonymous authentication permits users to access web resources without requiring them to provide a username or password, typically used for public-facing content or areas where no specific user identity or authorization is needed. The web server or application assigns an anonymous identity to the user, facilitating open access.

Biometrics authentication uses unique biological characteristics (e.g., fingerprints, facial scans) for identity verification, typically for secure access where identity is crucial.

Mutual authentication requires both the client and the server to authenticate each other, typically for highly secure and trusted communication channels.

Multi-factor authentication (MFA) requires two or more distinct pieces of evidence (e.g., password, token, biometric) to verify a user's identity, providing enhanced security where identity is critical.
