Two accounts possible?

Sorry to say but we cannot move items or profiles and game play from one account to another, Once something is purchased or a game played on one account it is permanently on that account

To make this clear.

Yes, to two different accounts, therefore two different players.

No, to the same account on two different systems, whether console or not. The same account on any console or with Fortnite, any system is still the same person.

This is true and if one plays across platforms like a Sony or via a phone app, one should be aware of that due to on some systems, especially with Fortnite, cross-play is limited. With that said, Xbox allows playing on any console with the account assigned
to you. Your son can play your games from the home console, but for him to have his own identity he needs his account.

Got to account.microsoft.com and go through the family and security settings. There you will find out how to safely set up your home network of gaming and also have the security of purchases and play times, etc. that you wish.

Hi,

Are you the main account holder? If you are you need to set his console as your home console.

Once you do this he can play his games on his console and when you log into yours it won't log him out.

Ah, I see. Forget my post then.

That would still leave 2 separate accounts though. They're wanting to combine everything onto one account.
