Apple TV v3 ITunes Two Factor Authentication
I have tried a few things and continue to get an error logging into my ITunes Account on my AppleTV 3rd Gen. The issue seems to be entering the Verification code without it timing out.
Question marked as
If you are attempting to enter the password and code together then it will easily time out. You will need to enter the password, then manually request a code, and then add it to the password. This way the time is used exclusively for the code.
