What Is Two-Factor Authentication in WordPress?

Two-Factor Authentication (2FA) in WordPress is a security feature that adds an extra layer of protection to your WordPress login process. Instead of only requiring a password, 2FA requires a second form of verification, making it much harder for unauthorized users to gain access to your site. This second factor is typically something you have (like a smartphone app) or something you are (like a fingerprint), in addition to something you know (your password).

How Two-Factor Authentication Works in WordPress

1. Initial Login Attempt:
   • A user enters their username and password on the WordPress login page.
2. Second Verification Step:
   • After successfully entering the username and password, the user is prompted to provide a second form of verification. This could be:
     • A code generated by a 2FA app (e.g., Google Authenticator, Authy).
     • A code sent via SMS to the user’s mobile phone.
     • A code sent via email.
     • A hardware token (e.g., YubiKey).
3. Access Granted:
   • Upon entering the correct 2FA code, the user is granted access to the WordPress admin dashboard.

Benefits of Using 2FA in WordPress

• Enhanced Security: Even if someone obtains your password, they cannot access your site without the second factor.
• Protection Against Password Theft: Reduces the risk of unauthorized access due to stolen or guessed passwords.
• Compliance: Helps meet security requirements and compliance standards for websites handling sensitive data.

Popular 2FA Methods

1. Authenticator Apps:
   • Apps like Google Authenticator, Authy, and Microsoft Authenticator generate time-based one-time passwords (TOTP) that refresh every 30 seconds.
2. SMS Codes:
   • A code is sent to the user’s registered mobile phone number.
3. Email Codes:
   • A code is sent to the user’s registered email address.
4. Hardware Tokens:
   • Physical devices like YubiKey provide a unique code or work via NFC or USB.

• Two Factor Authentication by David Anderson, Team Updraft
