Use the steps below to sign in to an Xbox One console other than your own and access your content that's saved to the cloud or access movies and apps that stream over the Internet (but not the games saved to your own Xbox One console).
From the Home screen, select Sign in in the upper-left corner.
Select Add new.
Type in the email address and password that you use to access your Microsoft account.
You’ll be shown a reminder of the privacy settings you’ve set for your account. These apply to any Xbox One console that you sign in to.
Change the colors on your Home screen to differentiate between you and others using this console.
You’ll be reminded of the gamerpic that’s associated with your profile, in case it’s been a while since you’ve been online.
Control who has access to your account by selecting Keep asking for my password. Otherwise, anyone can sign in to your account without your permission. This is especially important if you're signing in to a console that you don’t own or that you share with others.
When you’re finished, if you haven’t saved your password on this console, you can simply sign out. The next time that you use this console, you'll need to sign in with your Microsoft account email address and password.
