Recently, Yahoo sent out email telling users that their sign-in will be changing in October 20 and will be more secure. With that, they have notified users that old sign-in method after October 20 will no longer work. See below.

We love that you love using your Yahoo Mail. And we want to make sure
you always have the best experience. That’s why we’re reaching out
today.
We’ve noticed that you’re using
non-Yahoo applications (such as third-party email, calendar, or contact
applications) that may use a less secure sign-in method. To protect you
and your data, Yahoo will no longer support the current sign-in
functionality in your application starting on October 20, 2020. This
means that you will need to take one of the steps below to continue
using Yahoo Mail without interruption.
But don’t worry, you have options. Find an option that works best for you below:
Option 1: We recommend that you access your email using our free
Yahoo Mail app for iOS and Android or simply go to
mail.yahoo.com to access Yahoo Mail on the web.
Option 2: Keep your current,
non-Yahoo app, BUT follow a few steps to get it to sync with our secure
sign-in method. The steps vary across different email applications, but
in most cases, you will have to remove your Yahoo account from the app
and then add it back again to update the sign-in security. Use the
links below to follow the specific steps for your current application:
Option 3: You can generate a
one-time, unique password that will allow you to sign in to your account
using your non-Yahoo email application. Once created, this password
will continue to allow your app to securely sync your Yahoo email unless
you sign out (or are signed out) from your app. You can find
instructions on how to do this
here.
If you want more details on these changes, please visit our
help page.
If you’ve already taken action, we’d like to think you haven’t read
this far, but if you have . . . we sure appreciate the diligence!
Thanks for rocking that Yahoo Mail address!
Yours in your inbox,
The Yahoo Team

Fine and dandy until you try to set up email using the Amazon email app on a Kindle. The procedures will not work and finally Yahoo in its HELP revealed that Kindle Amazon native email support will be discontinued. The only choice on Kindle is to get Yahoo email app from the store OR go to website for Yahoo and into mail that way. So much for consolidating all email addresses into one app!
Well, this isn't the problem that now occurred. I did successfully on Thunderbird under Windows delete my old account and add the Yahoo email back. But, somehow, TWO Yahoo email accounts then existed next time I brought up Thunderbird You would think a simple removal of one would fix the problem. WRONG. Instead, you now get an error that a "User Account by that Name Already Exists ..." and this error does not allow removal or editing of ANY email addressed via the Tools-> Account Settings. Instead, I went to home page for Thunderbird and right-clicked one of the Yahoo Accounts. Then on resulting page I went to Account Actions and did remove. Did the same for other Yahoo email. Now added it back to establish new sign-in interface sync. That not only cleaned up the error for Yahoo, but did so for all other email accounts without having to do anything else. Go figure. NOW, I hope all is well!
