I have been locked out of one of my accounts for over a month now and I can’t sign in because whenever I try, a message pops up saying I have to wait for a verification code because of “too many failed attempts”. I have repeatedly tried after waiting over 48 hours without trying to sign in, I’ve tried signing in after a week of not attempting to, and I have tried using other devices. None of this is helping and the Google support is maddeningly unhelpful. What do I have to do to regain access to my account?
