Are security questions no longer required for Apple ID account security?

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?

Accounts with two-factor authentication enabled do not require or use security questions.

Do I still need to remember any security questions?

No. With two-factor authentication, you don't need to remember any security questions. We verify your identity exclusively using your password and verification codes sent to your trusted devices and phone numbers. When you enroll in two-factor authentication, we keep your old security questions on file for two weeks in case you need to return your account to its previous security settings. After that, they're deleted.

If you are enabling two-factor authentication on an existing account, you may need to answer the security questions to complete the process.

You might be asked to answer your Apple ID security questions.
