Watching on line

I have a couple questions concerning watching my cable channels I pay for online.

We have more than one email address for our account.  When I want to watch COX on line only 1 of the

login in passwords work.  This is the one for the main account owner.   This is a problem because if one of the other

folks in the house wants to watch on line I have to give them the password which is also a email password.

Why won't any of the email addresses linked to my account allow them to watch COX on line?

My next question, when will COX allow me to watch all of the channels I pay for when I am away from home?

COX removes some of the channels when not watching from home.  I can't even watch a local R.I. TV channel

when away from home.
