If I buy game pass ultimate on an alternate account will it cover my home account?

my father has a game pass ultimate. He's able to play pc/ultimate. my Xbox is home. When I try playing on the pc it asked me to buy it. how can you help me?

Are you logging in on your father's account, or your own account? Because my fiance wanted to play the Halo: MCC on the PC one time, but she had to be signed into my Xbox account in order to be able to play it because my account is Game Pass Ultimate. Otherwise,
you have to have your own Game Pass Ultimate subscription.

My girlfriend had recently got game pass ultimate and we said we would gameshare it. Her home xbox is my xbox and my accounts home xbox is on her console. The subscription is only showing up on her xbox and is not transferring to mine also how do i fix this?

Gamesharing through the "Home" feature does not share the Ultimate subscription. "Home" console lets you play any of her purchased and downloaded games even if they are from Game Pass. Your account will not show as having Ultimate, and your account will not be able to utilize Game Pass PC or cloud gaming. Those features are only for the account that actually purchased Game Pass Ultimate.

The Ultimate includes additional DLC (Fortune Island, Autopass and and and) that will be missing from your account.

If the price is too high for you, the Game Pass (which actually contains only the standard version) is an alternative because there is a special offer "Ultimate-Add-Ons-Bundle".

But do not forget, nobody knows how long a game is part of the Game Pass. So I prefer to buy what I really want and the Ultimate Edition was my choice.

Regarding Game pass on Xbox. If you have a game pass you can set your box as homebox.

Then, any other account can share your subscriptions, games, and apps on that Xbox. You can Buy Ultimate and then one of your sons when logged with your account on The PC can have a game pass. Then you must buy a game pass for PC to another son, but with
his account. If you want both of them to have their own PC game pass, then you must buy a game pass for each account, but with their accounts. Homebox

Thanks Smwutches! Yes, he's on my home console. But it sounds like I can't log into another console as myself and play the purchased version while he's playing the Pass version. Is that right? In other words, is the only option to get the game on his account (either buying or buying Pass Ultimate) ?
