Chosen solution

Look in Edit/Preferences/Privacy & Security/Passwords/Saved Passwords. Remove the account password, restart TB, enter a secure mail key when prompted for a password. Create the key on the AT&T site:

Are you using a secure mail key or the regular account password?

I am using the regular account password. It works when I access on the web, through Firefox. I could find no place where I could look at my password in Thunderbird. I deleted my Thunderbird account, then tried to set it up again. It recognized the email name and password, said it already existed and would not set up a new account ... so it appears not to be on my computer where the problem lies, the server decided it doesn't like me anymore?
