I had to get a security key in order to set up my at&t email on TB. Now I can get my incoming mail but cannot send without entering a pw. I think I need the same key for sending but forgot what it is. How can I find it? At&t doesn't help.

Chosen solution

Open Thunderbird's password manager Password Manager - Remember, delete and change passwords in Thunderbird and reveal the saved logins to see the secure mail key you used. Also, consider using a password manager (safe/vault) to securely store your passwords. There are many free and commercial options to choose from.
