Using HBO on multiple devices
HBO supports simultaneous streaming. This means that members of your household can sign in to HBO on different devices and stream different shows or movies at the same time.
Your sign-in credentials shouldn't be shared with anyone outside your household. For security reasons, the number of simultaneous streams is limited. If HBO is streaming on too many devices at the same time, you'll get a simultaneous streams message. If this happens, see Streaming on too many devices simultaneously.
Your TV provider might also support sub-accounts, which allows members of your household to have their own username and password. For more information, see Using sub-accounts in HBO.
