Answer: C
Multi-factor authentication would NOT include the use of a password or passcode.
Multi-factor authentication (MFA) requires the use of two or more verification methods to enhance security. A password or passcode is typically considered a single factor of authentication, thus making it insufficient on its own to meet the multi-factor requirement.
A) key card.
A key card is a physical token that serves as one factor of authentication. When used alongside another method, such as a password or a biometric measure, it qualifies as part of multi-factor authentication.
B) fingerprint scan.
A fingerprint scan is a biometric authentication method that serves as a distinct factor. When combined with another authentication method, it effectively contributes to multi-factor authentication.
C) password or passcode.
A password or passcode is a single factor of authentication and does not qualify as multi-factor authentication on its own. It is fundamentally a knowledge-based authentication method, and thus does not satisfy the requirement for multiple verification methods.
D) text message on a smartphone.
A text message on a smartphone can serve as a second factor of authentication when used in conjunction with another method, such as a password. It is considered a form of one-time password (OTP), thereby fulfilling the criteria for multi-factor authentication.
Conclusion
The correct answer is C because a password or passcode alone does not fulfill the multi-factor authentication requirement, which necessitates the use of multiple verification methods. Options A, B, and D all represent valid factors that contribute to MFA, while C stands alone as a singular method that lacks multi-factor capability. Therefore, C is definitively the correct response.
