Can I sign in to HBO on a device that I don't own?

Yes, you can use HBO on a device that 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, you might see an error about too many simultaneous streams. If you forget to sign out of a device you don't own, you can remotely sign out of HBO. To find out how, see How do I remotely sign out?
