Which of the following is an example of Identification?

Identification is the process of recognizing and establishing who a user is within a system. The correct example of identification from the provided options is a Social Security Number (SSN). An SSN serves as a unique identifier assigned to individuals, primarily in the United States, and is often used to confirm a person's identity within various systems and services.

While passwords, tokens, and biometric data are integral to the broader context of authentication, they function primarily to verify that an individual is who they claim to be. A password is something a user knows, a token is a physical or digital object that represents a user's credentials, and biometric data is a physiological characteristic used for authentication. However, the SSN acts as an identifier that establishes an individual's identity, making it the correct choice in the context of identification.
