I am developing a magazine reading app for Windows 8 (Metro). All the magazine issues should be buyable using in-app purchases. I need to uniquely identify the user that makes the purchases. If I pair the purchases with the device id (Windows.System.Profile.HardwareIdentification.GetPackageSpecificToken) and the user uses the app on multiple devices he will have to buy the content for each device again. I do not want that. Is there a way to uniquely identifiy user (and pair him with the bought content in the publishers system)?

    Windows.System.UserProfile.UserInformation allows you access to the current user’s info. You can also use Windows.Security.Authentication.OnlineId namespace if you need to authenticate them against Live and get additional info, with user consent.
