Thunderbird 91.4.0 has locked me out of my gmail account, AGAIN! It keeps asking me to enter password- " login to server imap.googlemail.com with username ***.*******@gmail.com failed. when I retry to enter my password that works fine elsewhere it just keeps flashing up the same message. It also flashes a notification at the bottom right of my screen saying " Alert from account ***.*******@gmail.com: Application-specific password required: https://support.google.com/accounts/answer/185833 (Failure). It leads to an error page. If I open my gmail account in a browser I don't have a problem. I don't like using using my various email accounts in a browser, that's why I've been using Thunderbird ever since Outlook Express disappeared. This isn't the first time that Thunderbird has done this but I don't see why I should keep having to change my gmail password just because Thunderbird keeps having a hissy fit. My wife has a gmail account and hers works fine, as do my other accounts with yahoo, outlook and hotmail. Thunderbird just seems to have problem with my gmail account. I would like to know why. I also DO NOT want keep changing my password.
