Despite reading similar support recommendations, Thunderbird V91.10.0 will not accept my passwords. I have three email accounts that I'm using with TB, and have used the same passwords for years. Now the program will not accept the passwords. Specifically, I cannot send outgoing mails. Incoming mails do arrive, but not the outgoing ones.

When trying to send an email, I get this message: "Log-in to server smtp.googlemail.com with user name [email address inserted here......@gmail.com] failed." Then, options for 'Retry' or 'Enter new password'. If I try to enter/create a new password, still it is not accepted. If I persist, I get this:"Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.googlemail.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

In Server settings/Authentication method, I tried switching from 'Normal password' to '0Auth2', but still the same problem.

Can anyone help with this? I'm lost....

Chosen solution

My Gmail POP and SMTP stopped working today as well. I updated to Thunderbird 91 and changed the following settings:

1. Select the `Account Settings` menu item from the `Tools` menu.

2. Click on your Gmail account and choose `Server Settings`.

3. Change the `Authentication method` pop-up menu to `OAuth2`.

4. Click on your `Outgoing Server`. Click the `Edit` button and change the `Authentication method` pop-up menu to `OAuth2`.

That solved the problem for me.
