@matigo Oh God. I HATE those.
Another Apple irritation. Enabling two factor authentication and using an older Apple TV. Every time Sidekick fires up HBO Now, I get notifications on my iPhone, iPad, MacBook Air and Mini. I have to accept them. Getting to the page to enter the code on the Apple TV is a pain in the rear but doesn't even seem to be necessary.
I need to disable it before I go nuts.
