Authentication issues after gmail password change
Hello, I'm afraid TB stopped working after I changed my gmail password. Whenever it tries to connect to the imap server, I get the oauth login prompt, fill out the password, confirm that I want to allow TB to access my gmail account, but after that, I just get the "Authentication failure while connecting to server imap.gmail.com."
I have OAuth2 set as the authentication method, I have cleared the saved passwords, updated TB, manually deleted obsolete files in the profile folder and basically tried every advice I could find, to no avail.
All worked well before the password change (the big end-of-may less secure app business did not affect me).
Currently, I have removed all my gmail accounts from TB and am trying to add them again. One of my gmail account uses 2FA, in this case, I also tried to use the app password. The other gmail account does not use 2FA, so I just used the regular password. In either case, I get the popup asking me to allow TB to access my mails, which I provide, but end up with "Unable to log in at server" message.
Any help would be greatly appreciated.

What is your anti-virus software?
Try to start Windows 10 in safe mode with networking enabled.
Does the problem go away?
Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.

With OAuth2 authentication you have to use your main Google account password, regardless of 2FA being turned on or off.

Ok, thank you for the info, I did not know that. However, this does not bring us any closer to resolving the issue.

You have to allow cookies in Thunderbird, at least temporarily for the Gmail authentication. https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20

Been there, done that. Any other ideas?

Ah, there we go.
My anti-virus is Eset Internet Security, and yes, trying to set up my account in safe mode worked. Furthemore, everything seems to work fine now, even out of safe mode. So it is safe to assume that the problem was my anti-virus blocking communication? Strange that it works now though.
Nevertheless, it works, so I'm not going to dig into it further. Thank you very much for your patience and help, christ1.
