A company wants to implement MFA. Which of the following enables the additional factor while using a smart card?
When using a smart card for Multi-Factor Authentication (MFA), an additional factor to authenticate the user is typically a Personal Identification Number (PIN). This combination provides two factors of authentication: the smart card itself (something the user has) and the PIN (something the user knows). This satisfies the MFA requirement by incorporating both a possession-based factor and a knowledge-based factor.
is user ID not also something you know?
Yes, but I think it is more common to use a PIN. It is hard for users to remember a user ID, especially if it is a long one.
A. PIN When using a smart card for Multi-Factor Authentication (MFA), the additional factor is typically a Personal Identification Number (PIN). The combination of the smart card and the associated PIN provides two factors of authentication: something the user has (the smart card) and something the user knows (the PIN).
The combination of the smart card and PIN adds an extra layer of security by requiring both a physical token and a knowledge-based credential for authentication
Factors - Something you know - Something you have - Something you are In the question they say that they want MFA. one of the authentication factors is a smartcard which is something you have. In order to have MFA you need to have different authentication methods, in this case smart card is something you have and the only other answer that isn't something you have is PIN. A PIN is defined as something you know.
Just imagine a debit or credit card
A. PIN
PIN is something you know, which satisfies MFA requirements (smart card is something you have)
