Set Up an Authenticator App for Two-Factor Authentication
Two-factor authentication (2FA) asks for a second code when you log in. With an authenticator app, the code comes from your phone, so you don't have to wait for an email or text.
Any time-based code (TOTP) app works, including Google Authenticator, Microsoft Authenticator, and Authy.
Set it up
- Go to Settings > My Profile > Security.
- In Two-Factor Authentication, open the authenticator app setup.
- Open your authenticator app and scan the QR code, or type in the setup key.
- Enter the 6-digit code the app shows and confirm.
- Save your backup codes somewhere safe, such as a password manager.
Logging in
After you enter your email and password, open your authenticator app and type the current code. Codes change every 30 seconds.
Important notes
- Each backup code works once. Use one if you lose your phone.
- If your backup codes are lost or exposed, create new ones from the Security page.
- Getting a new phone? Move your authenticator accounts to it, or set up 2FA again, before you wipe the old phone.
- If codes are rejected, check that your phone's time is set automatically.
