Can I change the answers to the security questions for my Apple ID?
Yes. You can change the answers to the security questions provided when you originally signed up for your Apple ID. Go to My Apple ID and click Manage your Apple ID. Sign in with your Apple ID name and password, go to the section Password and Security and click Reset your security information.
