How do I add Cox as my TV Provider for Single Sign-On on my iPhone?

Apple’s Single Sign-On feature allows iOS and Apple TV users to sign in to individual entertainment apps only once across multiple devices. For example, users can authenticate their Dish subscription through the TV Provider section of the Settings app on their iPhone, then access any Dish supported apps on any other Apple devices that share the same Apple ID. The only downfall of Apple’s Single Sign-On feature is that individual providers need to support the service, and at this time several major companies, such as Comcast, FIOS and even COX, have not come aboard.
