Backup codes let you sign in when you can't use your authenticator app. Some sign-in screens call them recovery codes, but they're the same thing. Each code works once.

The Backup Codes row only appears after you turn on two-factor authentication (2FA), a second check when you sign in. See Two-Factor Authentication (2FA).

Tomba gives you your first codes in step 3 of the authenticator setup. Click Copy all or Download to save them. Then tick I have saved these codes and click Done.

You can't view your current codes again, so get a new set if you've lost them or are running low.

Step 1. Open Settings > Security. The page is headed Security & Privacy.

Step 2. In Two-Factor Authentication, find the Backup Codes row. It shows how many codes you have left. Click Manage.

⚠️ Important: The next step cancels all your old codes. Replace any copies you've saved.

Step 3. Click Regenerate Codes.

Step 4. Click Copy all or Download to save the new codes, then click Close.

Treat these codes like a password. A password manager is a good place for them, or a printed copy kept somewhere secure. Don't keep them in your email or in a plain note on your phone.
