What is Authentication Credentials?

What is Authentication Credentials?

• A. A biometric measure used for authentication.
• B. A combination of the user ID or account ID plus the authentication factor(s) used to authenticate.
• C. An encryption key used to protect data.
• D. A backup copy of data.

Answer: (B)

Authentication credentials are what you present to prove you are who you claim to be. They consist of your user ID or account ID along with the authentication factor(s) you use to verify your identity, such as a password, a hardware token, or a biometric. The user ID identifies the account, and the factor provides the proof, so together they form the credential set the system checks before granting access. This is different from an encryption key used to protect data or a backup copy of data, which serve other purposes. For example, logging in with a specific user name and a password demonstrates the credential combination, not just a single factor.
