I can't turn off two-factor authentication and therefore cannot sign into my old Apple TV. HELP!
I sign in using my password, it asks me to enter two-factor authentication and there is no option to enter this on the apple TV.

See the following from Two-factor authentication for Apple ID - Apple Support
If you use two-factor authentication with devices running older OS versions—like an Apple TV (2nd or 3rd generation)—you might be asked to add your six-digit verification code to the end of your password when signing in. Get your verification code from a trusted device running iOS 9 and later or OS X El Capitan and later, or have it sent to your trusted phone number. Then type your password followed by the six-digit verification code directly into the password field.
