Cannot set up Thunderbird using AT&T email secure key
Hello, I am a Windows 11 user. I have used Thunderbird for many years.
I had a problem with Windows 11 and had to reload it. I also needed to reinstall all my apps including Thunderbird.
I have been trying unsuccessfully to reinstall Thunderbird for a few weeks.
I have a Lenovo laptop that is about 1.5 years old. I have Windows 11 Pro Verson 10.0.22000 build 22000, this comes directly from the Windows System information. I downloaded Thunderbird today, version 102.1.2 (64 bit) I have gotten AT&T email Secure Keys multiple times and pasted and also typed in the Secure Key where Thunderbird setup asks for a password. The POP 3 settings are identical to those provided by AT&T. When I click done, it checks the password and says there must be some problem with the password or user name.
I have browsed the help community numerous times, but cannot find anything that has allowed me to resolve my problem.
