I'm not understanding the issue you are having. Are you asking how to login into a different profile on Xbox.com, if so all you have to do is log out and sign back in with another one. If you are talking about Xbox Live, all you need to do is sign out
and sign back in with your profile you want to be signed in with. I hope this helps.
