The Epic Games launcher has a bizarre behaviour here. If you first sign in with your Xbox account, you can later sign in with the credentials of your Xbox account (email and password), as a 'native' account. I'm not sure what's shared, but that process made me uncomfortable. My hope is it's a password hash or they forward the sign in request to MS servers, but who knows.
