Explanation:

Define multi-factor authentication

Multi-factor authentication (MFA) is an identity verification method that requires a user to provide two or more verification factors to gain access to a resource.

Determine the minimum factors required

Single-factor authentication requires exactly 1 factor (e.g., a password). Therefore, "multi-factor" authentication must require at least 2 independent forms of evidence.
