Can I sign into HBO GO from a device that I don't own?
Yes, you can use HBO GO on devices you don't own. If you sign in on a device that isn't yours, be sure to sign out when you're done watching (go to Settings and choose Sign Out).
If you don't sign out of HBO GO, you might see an error about too many streams happening at once with your account. For more information, go to Error message: Too many simultaneous streams.
