I lost security questions/answers for my old Apple ID, so I can't do many things. Therefore, I registered a new Apple ID account by going to System Preferences → iCloud. I enabled two-factor authentication and provided a trusted phone number. The weird thing in this new account is that it didn't ask me to provide any security questions and answers.
I am afraid the stupid security questions/answers will cause new problems later on in my new account, I accessed the Manage your Apple ID webpage to find a way to provide it. But in the Security section of my new account, there are no Security Questions setup at all.
I am very confused about Apple ID security. Are security questions required or not? These security questions killed my old account, but no longer exist in my new account.
I just don't get it. Why don't I have them?
