Reauthenticate your Yahoo Mail account in third-party email applications

You can often do this by deleting your existing password from your email application settings, and then re-entering the Yahoo Mail password you use in this application, whether this is your Yahoo account password or a third-party app password.

If you use an app password to sign in to your account with the email application, you may need to delete your current app password, generate a new one, and use the new app password to sign in.
