What is multi-factor authentication (MFA)?
A.Using a very long password
B.Logging in from two different devices
C.Using the same password for two different systems
D.Authentication requiring two or more independent factors from different categories: something you know, something you have, or something you are
Why D is correct
MFA requires two or more independent authentication factors from different categories (knowledge, possession, inherence), making it significantly harder for unauthorized users to gain access even if one factor is compromised.
