Yahoo popup when using Thunderbird

After years of no problems, all the sudden when trying to log in with Thunderbird to my 2 email accounts, Login in Yahoo kept popping up as a popup. The reason this bothered me is I was already logged into Yahoo. After about 30 mins of messing around, I was finally able to login in and then Thunderbird continued to work as it always have. However, I did get an email stating that I had authorized a new 3rd party login from Thunderbird. All I really want to do is be sure all this was on the up and up and I did not just login into some 3 world scam site.

A TB update might have switched the authentication method on the account to OAuth2, the preferred method for Yahoo, gmail, AOL, so the authorization window you saw is expected. You should see a long token stored in Saved Passwords.
