Hello! i havent used Thunderbird or anything like it ever before and have a huge issue at hand! somebody hacked my google account and linked a thunderbird/POP/IMAP or whatever it is called. in my google/ Gmail account i have disabled all POP/IMAP, or other devices that are not mine yet the hacker keeps receiving the emails from the email i have resecured and can look at them. One of them is a EA account which he has used to recover everything on it. Now my actual question, is it possible to remove a Thunderbird IMAP/POP link through google itself or is that not doable? best regards and in hopes of someone quickly finding this, as a lot of money was spent.

Thanks in advance
