Extremely frustrated that Apple TV will not accept password with or without the 6 digit verification pin

Two-factor authentication keeps accounts (more) safe, in that you would know if your account was tried to be used on a new device. This cuts down on unauthorized use a lot, which helps users, and Apple Support staff, and of course accounting as well. Once activated (for more than 2 weeks), TFA is permanent for the account. Some functionality is not available without TFA. Once successfully signed in, you shouldn’t be bothered about TFA so often.

Two-factor authentication for Apple ID - Apple Support

Get a verification code and sign in with two-factor authentication - Apple Support

What is your model Apple TV? Identify your Apple TV model - Apple Support. There are some caveats for older devices:

______________________________

If you have an Apple TV (2nd or 3rd generation) and two-factor authentication for your Apple ID, then you may be asked to type your password followed by the six-digit verification code directly into the password field. Additionally, there is a time limit, after which the code becomes invalid.

Try this: First enter the characters of your password (do not submit yet), then manually request a new verification code, then append that code to the password (no spaces or other separating characters), and then submit. That should help you get passed the time limit.

Thanks for the follow-up. I’m glad that you found a solution.
