Two-factor authentication (2FA) adds a one-time code from an authenticator app on top of your password.

Enrolling 1. Go to Account → Security. 2. Click "Enable 2FA" and scan the QR code with Google Authenticator, 1Password, or any TOTP app. 3. Enter the six-digit code to confirm and save your recovery codes somewhere safe.

Account owners can make 2FA mandatory for all users. If you lose your device, use a recovery code or contact support with proof of identity.
