Answer: A

Explanation:

Option 1: Correct. Multi-factor authentication adds an extra layer of security by requiring users to provide more than one form of identification, such as a password and a fingerprint or a security token.

Option 2: Incorrect. Multi-factor authentication does not simplify the login process, but rather adds an additional step to verify the user’s identity.

Option 3: Incorrect. While multi-factor authentication can help restrict access to certain users, its main purpose is to provide an extra layer of security rather than additional authorization.

Option 4: Incorrect. While encryption is an important security measure, multi-factor authentication is specifically designed to provide multiple layers of security by requiring multiple forms of identification.
