Are you suggesting that Apple invented security questions for your account? Because that sounds highly implausible. Are you sure you didn't set up actual security questions so long ago that you simply don't remember doing it anymore?

I think I had this happen to me as well.

Wasn't an issue until I wanted to change my Apple ID password, for which the security questions are required.

Phoned Apple Support, and they took me through a dazzling array of security steps, involving my Mac, iPhone, payment methods, and the Apple ID website, before they allowed me to create new questions.

Happened with very old accounts to me as well, where no security questions even had to be entered at the time. The solution was to call Apple Support - they could do it over the phone - I think I had to verify some account details like street address, etc.

Can confirm that this also happened to me.
