π What is 2FA & MFA?
Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA) add an extra layer of security beyond just your password. With 2FA, you confirm your identity using something you know (your password) and something you have (a code sent to your phone).
π 2FA vs MFA
- 2FA: Always uses exactly two factors (password + one extra step).
- MFA: Can use two or more factors (password + biometric + token, etc.).
- Both protect you from password leaks and phishing attacks.
