If you've lost your 2fa access, first, try using another device. Download Google authenticator on it and use your Secret code that was given right when you enabled 2FA on your account.
If you still can't get acces to your account using 2FA, please, contact our support using live chat on our website or via email firstname.lastname@example.org
It should take less time to resolve your problem if you provide following info:
- Your email address
- A selfie with your ID
