I've came back few days ago, and i tried to log-in on my first account but the 2TA don't work on the website.
I'm not even sure to which email it is linked as when i tried to remove it i didn't got any mail, and now the only mail i had in mind is the one i use for my second account.
I'd start checking through emails that I've used. If no luck there, you need to contact [email protected] for support. Prepare to provide evidence of account ownership.
