What credential technology requires a combination of two or more credentials in a single unit?

• A. Single credential
• B. Mixed credential
• C. Two-factor token
• D. Biometric only

Answer: (B)

A mixed credential is used when two or more verification factors are integrated into one authenticator. This means a single device or token requires multiple credentials to prove identity, such as possession of a card plus entering a PIN or using a biometric check stored on the card. That combination happens within one unit, which is what distinguishes a mixed credential from other setups. The other options describe scenarios with only one factor or with factors kept separate. A single credential uses just one form of proof. A two-factor token typically provides a second factor via a separate device rather than bundling multiple credentials into one unit. Biometric only relies on a single factor as well.
