What does "something you have" authentication typically refer to?

"Something you have" authentication refers to a method of verifying a user's identity based on a physical object or token that they possess. In this context, a token you hold in your hand is a classic example of this type of authentication. This could be a hardware token, smart card, or mobile device that generates a unique code. It acts as an additional layer of security because even if someone's password were compromised, they would also need physical access to the token to gain entry.

The other options provided do not fit the definition of "something you have." A fingerprint and a voice print are examples of "something you are" authentication, as they rely on unique biological traits for verification. A password you memorize falls under "something you know" authentication, which is distinct from token-based approaches. These distinctions highlight the importance of "something you have" as a tangible element in the authentication process.
