Did Apple get rid of security questions?

yeah, security questions where a thing back in the two step authentication time. Apple upgraded to two factor authentication with recovery keys and trusted devices years ago. It is not recommended too use two step verification with security questions these days

Several years ago Apple transitioned to using two-factor authentication for additional account security. Accounts created since that time automatically use two-factor authentication and this indeed cannot be disabled.

Some people have older accounts from before two-factor authentication was mandatory on new accounts. Apple encourages those users to transition to two-factor authentication when signing in on their accounts because without it "your account is less secure and you can't use features that require a higher level of security." However, the support article also says in tiny, light-grey font: "If you updated to two-factor authentication inadvertently, you can turn it off within two weeks of enrollment." In other words if you have an older account, recently activated two factor authentication ("inadvertently" or not), and you're within the two week period for turning it off again, you should check for an email from Apple for a way to do this. If you don't see one about this, look in your junk mail folder.

Only set a recovery key if you want to take full responsibility should your account have problems such as you forgetting your password and have no trusted devices.
