What is Multi-Factor Authentication?
Multi-Factor Authentication — Multi-Factor Authentication (MFA) is a security mechanism that requires users to provide two or more independent verification factors — something they know, something they have, or something they are — to prove their identity.
Multi-Factor Authentication Explained in Detail
MFA significantly reduces the risk of account compromise because even if one factor (e.g. a password) is stolen, the attacker still needs the additional factor(s) to gain access.
Authentication Factors
- Knowledge — Password, PIN, security questions.
- Possession — Hardware security key, authenticator app, SMS code.
- Inherence — Fingerprint, facial recognition, voice print.
MFA Best Practices
Phishing-resistant MFA methods (FIDO2 hardware keys, passkeys) are strongly recommended over SMS-based codes, which are vulnerable to SIM-swapping attacks.
