Xbox ID is a real-time cloud service that gives you access to your Xbox credentials and your account data from an PC or console. You can get everything from games, movies, music and more based on the authentication you have in place for Xbox. If you really need it, Xbox ID will let you log into your Microsoft Account on any PC or console that has internet access. You just need to go a little bit crazy for this to work though. Basically, you will have to create a new user account with all of your friends and then add them to your account so they can access your games.
