Share Xbox Live Gold from Xbox One to Xbox 360: is this possible?

For the Xbox 360, there are no sharing features for Xbox Live Gold. Each account will need Gold to go online with the Xbox 360.

It is, however, possible for the both of you to play online (with one paid gold subscription) in "split-screen mode" offered in some games, but only on the same Xbox. One player would need to sign into the Gold-enabled account, and the other would have to
sign into a temporary "Guest" account. You will not be able to go online if one of the signed-in players have "Free" status (non-Gold).

The reverse is true for the Xbox One, though, as it offers plenty of
Gold-sharing features.

Hiya, Amy!!

Paul from Xbox Forums Team here to assist with the situation, it looks like we just want the kids to be able to play together while one of the children is at their friends house. This is possible using one Xbox live gold subscription and two different accounts.
It's possible due to our amazing benefits of Gold Sharing. When one account has an Xbox live gold subscription you can share that subscription with one console. Here is a guide about

gold sharing and how to proceed. Hope this answer was able to solve the problem. Thank you.

Happy Gaming!!

Yes, the xbox live gold shares between the Xbox 360 and the Xbox One on one account, so if you have gold one one you have it on the other for free, just log in on the same account on both devices, but only one can be online once at a time.

The My Home Xbox feature to share gold does not share across to xbox 360 backwards compatible or the real xbox 360, so if they need to use the xbox 360, they will each need gold to play on that console.

About the xbox 360 gamer profile reset, can you explain more about that? If you mean moving to Xbox one from the xbox 360, your achievements are not reset - but you may have to rebuild your progress on the Xbox one version of the game if it's not backwards
compatible from xbox 360.

Not on the Xbox 360. On the Xbox One, Yes!! Here you can read how that works:

Hello Doe,

Thank you for keeping us updated on the issue. The
Xbox One is able to share Xbox Live Gold from one account to all accounts on the console. The Xbox 360 does not have the ability to share one account's Xbox Live Gold to all other accounts on the console. The Xbox One will store saved data in the cloud
as long as the console is connected to the internet. The Xbox One will also save backwards compatible data to the cloud. If you are moving from Xbox 360 to Xbox One, we recommend

uploading your saved data to the cloud from the Xbox 360. The link we provided will have the steps on how to complete that process. Be sure to let us know the results!
