Two Factor

The Two-Factor plugin adds an extra layer of security to your WordPress login by requiring users to provide a second form of authentication in addition to their password. This helps protect against unauthorized access even if passwords are compromised.

Setup Instructions

Important: Each user must individually configure their two-factor authentication settings.

For Individual Users

1. Navigate to your profile: Go to “Users” → “Your Profile” in the WordPress admin
2. Find Two-Factor Options: Scroll down to the “Two-Factor Options” section
3. Choose your methods: Enable one or more authentication providers (noting a site admin may have hidden one or more so what is available could vary):
   • Authenticator App (TOTP) – Use apps like Google Authenticator, Authy, or 1Password
   • Email Codes – Receive one-time codes via email
   • Backup Codes – Generate one-time backup codes for emergencies
   • Dummy Method – For testing purposes only (requires WP_DEBUG)
4. Configure each method: Follow the setup instructions for each enabled provider
5. Set primary method: Choose which method to use as your default authentication
6. Save changes: Click “Update Profile” to save your settings

For Site Administrators

• Plugin settings: The plugin provides a settings page under “Settings → Two-Factor” to configure which providers should be disabled site-wide.
• User management: Administrators can configure 2FA for other users by editing their profiles
• Security recommendations: Encourage users to enable backup methods to prevent account lockouts
