I need to reset 2FA on an account, that I no longer
have the phone. And they want the eth address, that
I sent a deposit to. Well, all that is on the phone, that was
broken. Sure, I should've written down my 2FA code.
But we've all made that mistake.
Next time use Authy instead of Google Authenticator, it saves your 2FA data on the cloud, so no problems if you lose your phone.
I understand what you are up to now...
