Authenticator setup secret
Scan the QR code in an authenticator app or enter the setup secret manually. Anyone with a copy of the QR code can generate the same codes, so do not send or store the image in an unprotected location.
Current verification code
The first six-digit code confirms that the app was configured correctly. Tetri will then ask for a new code during sign-in and protected changes such as updating the password or email.
Recovery codes outside the authenticator device
Each recovery code works once. Store them in a password manager or another protected location you can access without the phone.
What changes after activation
Disabling two-factor authentication requires a valid code. Afterward, access depends on your password, passkeys, and linked services, so check those methods separately.
