Reset Apple ID Security Questions

If you see the message "not sufficient information", read this link:

Security and your Apple ID - https://support.apple.com/HT201303

"Without proof of your identity ... and other carefully selected criteria, Apple Support can't help you perform any actions on your account." If you are still using security questions (see below) then you knowing your security question answers is the exclusive way, apart from potentially "other carefully selected criteria", of proving to Apple that you are the owner of that account.

Apple does have "Account Recovery when you can’t reset your Apple ID password" ( https://support.apple.com/HT204921 ) which it specifies is available for "when you don’t have enough information to reset your password." However, it also states it is "if you use two-factor authentication" which you may not be if you are still using security questions. You can investigate if this is even available to you.

It may ultimately prove very difficult to find satisfactory resolution to forgotten security questions if you get the "not sufficient information" message (e.g., https://discussions.apple.com/thread/252410816 ). For quite some time now Apple has been very strongly urging users to use Two Factor Authentication instead of security questions. --> https://support.apple.com/HT204915 "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."

With that in consideration you can try to "Contact Apple for help with Apple ID account security".
