Add extra users to your Apple TV in Settings
Allow all the family to enjoy Apple TV by adding multiple accounts to a single device
Although you could allow everyone in your household to access Apple TV using one account, it can start to get messy and impersonal. If one family member has been watching a particular series, it will be their content hogging the ‘Up Next’ list. Recommendations will also reflect everything watched by a household. And that’s before you get to content preferences and purchases.
