Apple TV Family Sharing
Family Sharing lets you share apps and viewing privileges with up to six family members. One adult in your household—the family organizer—invites family members to join the family group and agrees to pay for any iTunes Store or App Store purchases made by family members.
Important: You can’t initiate or configure Family Sharing directly on Apple TV. It must be done on a Mac or iOS device. To learn more about setting up Family Sharing, see Set up Family Sharing.
