How do I permanently unlink my email from Outlook for Windows?

I've tried everything, I even changed the login credentials and it still logs in automatically without even giving me the option to enter my password and not even the authenticator works for that. Is there any solution? Does anyone know how I do this? Or is it just a complete formatting as I don't want it to automatically log into my device, for security reasons.

I'm not sure exactly which version it is, but this is it.
