You can log into as many devices as you like with your member username, however, your profile can only stream on one device at a time. For example, you can’t stream from your computer and from your phone at the same time.
To add ADDITIONAL profiles, like for a friend or roommate, all you have to do is add another profile to your account for $1.00. Go to HIDIVE.com/account and click on the add stream button. This way, everyone in the household can watch what they want, when they want, for only an extra dollar per month.
