Which of the following is an example of a "something you are" authentication? Response:

Least privilege is an authorization principle that restricts access to the minimum necessary for a user to perform their job, not an authentication method.

Biometrics, such as fingerprints, facial scans, or iris recognition, exemplify 'something you are' authentication because they rely on unique, inherent biological or physical characteristics of an individual to verify their identity.

Least functionality is a security principle stating that systems should only provide the minimum necessary functions, not an authentication method.

Multi-factor authentication (MFA) is an approach that combines multiple different authentication factors (e.g., something you know and something you have), but it is a method, not a specific factor type itself.
