No, the process is to give you a password for use only for one email setup. Thunderbird uses that as your password. If you were to setup more PCs, you would need to get another one-time password for each PC. This process of providing passwords for each setup is becoming more common with email providers.

David, thanks for your reply. You are correct. I don't have to keep requesting new one time app passwords; got a little panicked in the midst of changing a number of different password. But I don't know why I coudn't just continue to use the same log in credentials I use for logging in to the AOL/Verizon.net web mail. That used to work just fine. Seems like just another dose of gratuitous aggravation.

It seems to be a transition happening to many users, as it seems daily I see people needing a separate password for their PC. It is supposed to be tighter security; at least, that's what I hear.
