If you see the error "Google Authenticator code is incorrect or expired" when you log in to your Coinmatics account after entering your 6-digit authentication code, then:
- Check that the code is up to date (you may have more than one key generated).
- Reset your device.
- Try the following:
- synchronize time between your phone and the Google Authenticator app (for Android);
- synchronize time on your phone with world time (UTC) (for iPhone).
If the above methods don't help, you need to disable two-factor authentication. For more information on how to do this, please check out our article.
