Doubt regarding Xbox Game pass Ultimate

Sharing account information is a violation of the code of conduct, so you do not want to sign into his account to download any games. That would put both of you at risk for being banned.

If he were to set your console as his Home, you can share is subscription and continue your progress, but the Home setting is only meant to be used on your own console.

If you set the console as your Home for the 2nd account, you can share them with the other account. https://beta.support.xbox.com/help/hardware-network/console/my-home-xbox

Okey thanks for letting me know. Can i still play my games if i buy Pass Ultimate to my second account in my own console? There is 2 accounts in my Console. Both are mine. When i purchase to my secondry account can i use it on my primary account in same
console? Or does it apply to my scndy account only?

You'll keep the download. You won't have to redownload it unless you uninstall it.

Hey ashwinjr

Thank you for taking the time to post this on the Xbox Forums. We understand that you are currently inquiring about a game you installed.

As stated by Xbox Forums MVP Ambassador and Moderator
Smwutches, that game will remain installed on your console until you decide to

uninstall it. Even if you no longer have the Game Pass subscription, you will still have the game on your console, however, unless you purchase this game or renew your subscription, you will be unable to launch it.

If you purchase the game, you will not need to install it once more since its already installed on your console.

I hope this was able to clarify further on this matter.
