Activating HBO GO on multiple devices
You can activate HBO GO on multiple devices to let members of your household watch different shows at the same time.
HBO is a household subscription, so don't share the credentials you use to access HBO GO with people outside your household. For security reasons there are limitations on the number of videos that can be watched at the same time with a single HBO GO account.
