What is multi-factor authentication (MFA) and why is it important?

MFA means you must provide more than one type of evidence to prove your identity before accessing an account. This typically combines something you know (like a password), something you have (a token or mobile device), and sometimes something you are (a biometric). The strength comes from adding multiple verification methods, so even if one factor is compromised, the attacker still needs the other factors to gain entry. That’s why this option—requiring multiple verification methods and strengthening defense against unauthorized access—is the best description of MFA. The other descriptions describe single-factor authentication (only one method, like a password), relying on network location alone (IP-based access), or insecure practices (recycling credentials), which don’t provide the layered security MFA offers.
