Set up Google Authenticator

Google Authenticator shows a new 6-digit code every 30 seconds. You enter it when logging in and paying, so a stolen password alone cannot move your money.

1. 1Install “Google Authenticator” from the App Store (iPhone) or Google Play (Android).
2. 2On your computer, open Profile & Security → Google Authenticator and start setup.
3. 3In the app tap “+” → “Scan a QR code” and scan the code on screen.
4. 4Enter the 6-digit code from the app and click “Verify and save”.
5. 5Save the 8 backup codes shown once with “Download backup codes”, then confirm.

There is no official web version. You can use the Authenticator browser extension (publisher authenticator.cc); its codes work the same way.

1. 1Install “Authenticator” from the Chrome Web Store, Edge Add-ons or Firefox Add-ons.
2. 2Pin it to the toolbar from the puzzle-piece menu.
3. 3Open the setup page, use the extension’s scan button to select the QR code, or copy the key and add it manually.
4. 4Enter the 6-digit code, save, and keep your backup codes.

• New phone: click “Change authenticator”, verify with your password and payment PIN, then set it up again.
• Lost phone: log in with a backup code; if you have none, request a reset on the setup page for manual review.
• Sub-accounts: ask the main account to reset it under Team.

Never share the QR code, key or backup codes — not even with support. If codes keep failing, turn on automatic time on your phone.
