To connect a Yahoo Mail account to Klearbox, you need a Yahoo app password. This works for Yahoo addresses such as yahoo.com, yahoo.de, and other Yahoo domains. Sign in to your Yahoo Account Security page, create an app password under External connections, name it Klearbox, and paste the generated password into Klearbox. Use your full Yahoo email address as the username. If Yahoo does not show the app-password option, try a browser you have used with Yahoo before and avoid incognito mode.
