Apple TV is not allowing me to sign in. I have one of the first apple TV (model A1469) I had to reset all setting, but now it won't allow me to sign-in iCloud.

Thanks Urquhart1244 Oh is that how you get around that? I actually refused to update to two factor because I couldn't use my old AppleTV 3 (granted I do have AppleTV4K Gen 2) but still use the old one now and then. I wound up changing it back. Sounds like there is a workaround :)

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.

I have the exact same hardware/software version, with the same issue.

The software is in the last version available.

Yesterday I got a problem with Netflix authentication (basic things already checked, username, password, etc). According to Netflix, I should try typing the username and password directly from the remote control. I did it and did not work.

After that, I followed the next Netflix recommendation and reset the hardware. At this point, neither Netflix nor ICloud was able to authenticate. For iCloud, I tried with the wrong password and correctly got the wrong username/password error. Using the correct username and password, I was asked for the 6-digit two-factor authentication number. Typing at the remote control after the password authentication or including it at the end of the password as suggested, I got the same error.

I also tied the same process using restore rather than reset but got the same error.

Any hints?
