If you have access to your Authy/Google Authenticator, but the 2FA codes are not accepted by your Changelly PRO account for some reason, please check the following tips:

1. Make sure that your phone and your computer use the same correct time and time zone.

2. Check the time zones on the Settings page of your Changelly PRO account.

3. Check that the app you use to generate the 2FA codes is the same you used to set up your 2FA on your Changelly PRO account.


If the problem doesn't disappear, please try to log in using the backup code. 

Now you should be able to log in, switch 2FA off and enable it using a different app or device.
