Troubleshooting guide
My double authentication code is rejected
Use a current code or an unused backup code; resetting a password does not remove double authentication.
Use the correct code
Verify the code comes from the Dialova entry in your authenticator app. Temporary codes change: if it's about to expire, wait for the next one before validating. A code already accepted shouldn't be reused.
Also verify the time on your phone: temporary codes rely on a correct time. Avoid rapid attempts; they can trigger a limit.
The phone is no longer available
Use one of the backup codes saved during activation. Each code can only be used once. Don't share your codes and don't add them to a screenshot intended for support.
If a session still allows you to open Settings → Security, check the suggested actions. Some may themselves require 2FA proof; an open session doesn't guarantee you can remove this protection without a code.
Neither code nor backup works
The forgot password link isn't a way to bypass two-factor authentication. If you have no usable proof, contact the team to examine recovery possibilities. No recovery is guaranteed by a simple request or by knowing a nickname.
