A. True.

Explanation:

Authentication in computer technology can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.

Hence, if the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing.

This simply means that, when a user enters his or her private key (password); the authenticator matches the private key to the uniquely defined credentials. Permission and access is granted by the authorization system right after a successful authentication.
