My sign-in attempt was prevented

If you get the Username or password invalid warning and the Sign-in attempt prevented email when you try to connect your Yahoo Mail with Thunderbird, Yahoo has blocked Thunderbird from connecting because it's a "less secure" non-Yahoo app. In Thunderbird below 68.5 you could enable an option to allow apps that use less secure sign-in in your Yahoo Account. See this Yahoo support page for instructions.

In Thunderbird 68.5 you can change the POP server to pop.mail.yahoo.com (port 995 as usual) and will get a prompt from your Yahoo ISP partner to login; this accomplishes OAuth 2.0 key exchange in Thunderbird which will carry forth to authenticate the particular Thunderbird client in future logins.
