Problems with two factor authentication

Thanks your advice did the trick. This is a 1st generation Apple TV. It's slightly bigger and thiner than the generation 2. I have both generations. So to be clear if your Apple ID password is long and complex in other words secure, 2 Factor Authentication is very difficult to accomplish! Not only is the time out interval too short (About 30 seconds), I also blame it on the tiny and slippery Apple remote and ridiculously sensitive on-screen keyboard. I had to "Practice" speed typing the password plus code generated in the text on my phone like 4 times before getting it right in the time limit Apple allows. I set my phones' screen "Auto Lock" setting to "Never" so when the code appeared I would've to fumble with turning the phone screen on. Everyone recommends you use complex passwords but then their devices don't give you enough time to enter them or you forget them! Very frustrating!

Oops! You are correct! I have 2nd and 3rd generation Apple TV's. Thanks for all your advice! Everything works now. Just have to be lightning fast on the online keyboard to make it happen. Hope I don't need to do that very often.
