Does the ipad share your tv provider online login info with other apps?

I gave that info to Cartoon Network app, then I downloaded another app, right when opening it for the first time, there is it was, my tv provider in in the top right already logged in, even tho it was the first time I ever opened that app, did the Cartoon Network app share my login info, was it the ipad itself

if the apps were from the parental corporation (TBS) they probably confirmed your TV provider by checking your ID for you.
