What is the difference between SFA and MFA?

The correct answer is C. SFA uses one authentication method, while MFA uses two or more authentication methods. Single-Factor Authentication (SFA) requires only one form of proof of identity - typically something you know (a password). Multi-Factor Authentication (MFA) requires two or more independent authentication factors drawn from different categories: something you know…

Explanation

Single-Factor Authentication (SFA) requires only one form of proof of identity - typically something you know (a password). Multi-Factor Authentication (MFA) requires two or more independent authentication factors drawn from different categories: something you know (password/PIN), something you have (token/smart card), or something you are (biometric). Using multiple factors significantly reduces the risk of unauthorized access, since compromising one factor is insufficient to gain entry.
