Multifactor authentication (MFA) requires more than a password to prove identity. Even if an attacker steals a password, they cannot access an account protected by MFA without also possessing the second factor. It is one of the most effective controls against account compromise.
The Authentication Factors
Something you know — a password or PIN. Something you have — a phone, hardware token, or security key. Something you are — biometric authentication. The strongest protection uses factors from different categories.
Which Methods Are Secure?
Authenticator apps and push notifications are modern and secure. Text message (SMS) authentication is less secure because SIM swapping attacks can intercept codes. Hardware security keys are the strongest option for high-risk accounts. Avoid email-based second factors.
