I cant change my security questions in order to sign in

Hello,

Try the directions in the article If you forgot the answers to your Apple ID security questions - Apple Support for resetting your security questions:

"Reset your security questions

1. Go to https://iforgot.apple.com/ .

2. Enter your Apple ID, then select Continue.

3. Choose the option to reset your security questions, then select Continue.

4. Enter your Apple ID password, then select Continue.

5. Follow the onscreen steps to verify your identity. The information you’re asked to provide may vary based on your account details and other factors. If you don't get any options to verify your identity, you can't reset your security questions at this time.

6. Choose new security questions and answers and select Continue."

If you get a message about not having 'sufficient information', you will not be able to reset your security questions.* Realize that several years ago Apple transitioned to using to two factor authentication instead of security questions and has been encouraging users to switch to the newer security system. Your next recourse will be try to change to two factor authentication as outlined in this article --> Two-factor authentication for Apple ID - Apple Support Follow the instructions in the section "Turn on two-factor authentication for your Apple ID"

If you wish to speak with Apple about this, contact with Apple ID account security using the information in this document --> Contact Apple for help with Apple ID account security - Apple Support

"If you’ve forgotten your security questions, there isn’t a way for Apple to reset them for you, or another way to access your account. You would need to create a new Apple ID, which also means you won’t have access to previous purchases or data stored in iCloud."
