Check the account and clock
Make sure you selected the correct account entry. Enable automatic date and time on your device, then generate a fresh code.
Check the settings
Use the original enrollment settings. A different algorithm, code length, period, or replaced secret can produce codes the service will reject.
Avoid repeated attempts
Wait for a fresh time window if a code is about to change. Follow any rate limit shown by the service rather than continuing to submit codes.
If access is still blocked
Use the provider’s recovery codes or official recovery process. This website cannot disable 2FA or retrieve the server’s secret.
