We do understand that you are trying to watch a DirecTV channel MB and it is asking you for a password.
The reason behind that is: it is 3rd party application, that is not governed by DirecTV, but we are partnered with the app. It should be asking you for DirecTV username and password, and then the app should redirect back to MLB.
How this helps.

If you mean the MLB app, that is owned by MLB, not DirecTV. So like other individual apps you select your TV provider (DirecTV in this case) and put that TV providers login info.
Just because it is in your package doesn't mean you don't have to login on website or app.
