Authentication is a process of ensuring that an entity is who they say they are.

• A. True
• B. False
• C. Not always
• D. Depends on context

Answer: (A)

Authentication is the process of proving that an entity is who they claim to be. This is done by presenting credentials or proofs—such as a password, a token, a biometric trait, or a certificate—and having them checked against trusted records. The goal is to confirm identity before granting access, so the statement is true. In practice, while there are various methods and sometimes context-specific nuances (like device-based trust) that influence how authentication happens, the core idea remains: authentication aims to establish that the entity is indeed who they say. This is distinct from authorization, which decides what actions or resources the authenticated entity is allowed to access.
