apple TV is requesting a verification code when I have already entered my username and password. the request is to enter the verification code sent to my devices???

Hi. You've enabled 2-factor authentication, possibly with your last iOS update. The code is being sent to your "trusted device", probably your iPhone. Do you have Apple TV 4 (small black remote) or an earlier model (silver remote)?

Greetings. I have a 2d generation AppleTV. The software is current. The AppleTV prompts me to enter the verification code, but does not provide an input method. The screen shows 'enter code' with the SUBMIT button. There is nothing to input the code.

Hi. Have you tried adding the code to the end of your password, no space or punctuation?
