Weekly Sign ins

I have a DirectTV account, and I also use streaming apps like the ABC app, the NBC app, Fox Sports app, ESPN app, etc on my smart devices and my mobile devices, and I sign into those apps with my DirectTV account. 

Why do I get kicked out of every single streaming app every seven days to the hour on my devices? This has been going on for years, and it's very annoying to have to constantly put in a code and verify my DirectTV account every seven days. 

And I realize that I can install the Direct app and sign into my account on a mobile devices and my smart devices, but sometimes the individual network apps have different content than the DirecTV app, and signing in once a week is absurd. I do use the DirecTV app with no issues. It happens across all of my mobile devices, whether Android, or Apple streaming devices, and it happens on every streaming app I use that I use with my account.  I could see if it was just ABC or just Fox Sports, but it does not matter if it's TBS or NBC I get kicked out every seven days. 

What can be done about this?
