I am in control of the same email. I try to log in to that google account, I get an email with an OTP, I put it in, and ... google is unhappy because having control of the email is not enough, I need to have a similar computer/ip to 13 years ago.
All I want to do is shut down this google account, to make sure nothing about it happens that I am unaware of. If I it didn't exist, surely control of the email would be enough to create it in the first place...
I've been trying to recover that account approx. once a month for the last couple of years (for the purpose of deleting it. ...), to no avail.
I got locked out because of an old phone number I no longer had access to. Waited until I went back to my old home town. Tried again and there was no request for the phone number. Got in and updated everything.
