A Sync Box belongs to a Hue home and its Bridge, so sharing follows the Hue account. Reports say the owner can add users under Device Sharing in My Profile, giving administrator or lighting rights, so others can start sync and pick modes in the Hue app. Anyone in the room can also use the box with the TV remote through the IR receiver and CEC, without an app account. If a person cannot control sync, check they accepted the invitation, use the invited account and that the Bridge and box are online.
One box drives one entertainment area, and reviewers note that a separate box is needed for each area to sync at the same time, so a household with two TVs needs two boxes. Apple Home, Alexa and Google can also start sync if linked;
The checks in more detail
the Hue page lists compatibility with Alexa, Google Home, Apple Home, Matter, SmartThings and Sonos, with voice assistants needing a Bridge. If you sell the box, remove it from your account and reset it. Keep account security strong and remove people who no longer need access. Set sync intensity in the app so it suits everyone. Keep a list of who has access and review it when someone moves out. A new user who sees nothing may be on a different account. Show family the remote controls once. A household that shares one TV will find the IR remote and CEC route simplest, since nobody needs the app to start sync.
Because each entertainment area needs its own box, a household should decide which room matters most before buying, since the box cannot be split across two TVs.
