My account bricks consoles and/or cannot be used to log into XBox systems. What is going on.

In a word, no.

What most people call game sharing is actually just the home console feature. Microsoft accounts cannot share their games with other accounts, what's actually happening is an account defines a particular console as their home console, allowing their licensed software to be used without needing their account to be logged in. If your sister has defined your xbox console as her home console, any user on that console can use her software, but they can only be used on other devices by her account.

To my knowledge, you cannot define a computer as a home console, only xbox consoles.

I have this Same setup for My kids. What you have to do is make the Xbox the Family is going to use your Home console. You don't have to be logged in for the to use the games on that system. Then you put your Profile on the other system and you can log
in there to play the games with them.

Example: My Home Xbox is my Xbox one S (my profile and all the family profiles installed). The kids use that one to play digital games I've purchased and to share my live account. My Xbox one X only has my profile. I can log in there to access my digital
games and use my Live features.

it works really well with a two system setup.

Hope that helps.

No, you want us to log in to the account and we CANNOT

WE DO NOT HAVE ACCESS TO THE EMAIL.

The only place it's logged in currently is the Xbox one console.

I don't know what else to tell you dude.

No, you cannot use your game pass ultimate on 3 Xbox consoles at the same time. For starters, you cannot log in on the same account on multiple Xbox consoles at the same time.

What you can do is share your game pass ultimate subscription on one console, by setting that console as the home Xbox. Once you have done that, then anyone using the Home Xbox can access the game pass ultimate subscription without having to log in with
the account that has the subscription.

You can still log in with the account that has the subscription and play your games and access gold as much as you want on any Xbox, and your son can use his account on the home Xbox and access the subscription on there.

For more info on the Xbox Home setting have a look here.

when you load an ea game on the xbox console be it 360 or one and dont log into an ea account it usually creates one, you can log into ea with an xbox account or email, it is a daft system.

you need to log into ea with your xbox account and remove the link then log into your normal ea account with the email address and then link.

if you cannot do it then open a ticket with EA for assistance.
