If you have irrevocably lost access to a device with 2FA, you can disable 2FA. To disable 2FA let us know your Recovery PIN (which you got while opening an account with Chain Group Escrow Service, it looks like 000 000). There is no other way to restore access to the account.
If your device showing incorrect 2FA tokes, it caused by incorrect device clock settings. Your clock must show correct local time, date and time zone to work properly. Android and Windows phones have an option to correct for time errors inside the Authenticator app properties, if you do not wish to sync your clock. iPhones must be set to use internet time to make sure the clock is synced properly.
