HBO GO needs primary password

I just got HBO for my wife and kids. I couldn't care less about it. They were excited about the HBO GO app and downloaded it to their tablets. They were disappointed to find out that every time they have to launch it they have to log in with the primary cox account information... That's my log in and my main email account. I do not want to keep logging in everyone when the app asks for my log in, and I do not want to share my username and cox email password with the kids... I found that this poor software design is in other cox applications as well. - Is the app going to be fixed to support all cox email users under my account? - Is there a way I can setup a HBO GO only username and password that's not my email? - Can I create a dummy account and assign it as the primary user and make mine a secondary so everyone at home can use those primary credentials and I still maintain my privacy? Thanks,
