It's easy to access your game and console data that's saved to the cloud from another Xbox One console. You just have to sign in. Here's how:
Scroll left from Home to open the guide.
Select Sign in.
Scroll down and select your account to sign in.
After you've signed in, scroll left from Home to open the guide.
Select Add new.
Type the email address or phone number you use to sign in to your Microsoft account.
Enter your password. If you've forgotten it, select I forgot my password, and then follow the instructions to recover your account.
Review the privacy statement summary, and then select Next.
Select your Sign-in and security preferences.
Note If this is not your console, you may want to select Lock it down to require a password to sign in. That way, if you want to leave your account on this console for future use, no one else will be able to use it.
Check out how you look on Xbox, and then select Next.
Choose your color, and then select Next.
Note The preference that you're currently using at home appears with a checked box.
Press the Xbox button on your controller to return to the Home screen.
When you're finished playing, 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 credentials.
