Last updated on October 19, 2024

Add a Second Layer of Protection to Your Account

Two-Factor Authentication (2FA) prevents unauthorized access by requiring a one-time code in addition to your password. We support both authenticator apps and email-based codes.


Why Enable 2FA?

  • Blocks attackers even if they discover your password.
  • Alerts you immediately if someone tries to log in.
  • Required for contributors with elevated permissions (authors, broker admins).

Enabling Authenticator App 2FA

  1. Log in and navigate to Profile → Security.
  2. Click "Enable Two-Factor Authentication".
  3. Choose "Authenticator App" (recommended).
  4. Scan the QR code using Google Authenticator, Authy, or Microsoft Authenticator.
  5. Enter the six-digit code generated by the app and click "Verify".
  6. Download your backup codes and store them securely.

Email-Based 2FA (Backup Option)

  • Choose "Email Codes" if you can't install an authenticator app.
  • Each login triggers an email with a one-time verification code.
  • Less secure than app-based 2FA but better than password alone.

Managing Devices

  • View active sessions on the Security page.
  • Revoke access to any device you don't recognize.
  • If you lose your phone, use backup codes to sign in and disable 2FA temporarily.

Troubleshooting

  • Authenticator code rejected? Ensure device time is set to automatic.
  • Lost access to 2FA device? Use backup codes or contact support with identity verification.
  • Not receiving email codes? Check spam folder, whitelist [email protected].
