If you own and iPhone or iPad you almost certain have an Apple ID. It's what you use to log into iCloud and iTunes, and it's what a lot of new iOS 8 features like Continuity use to make sure you're you, and to keep your documents and data private and secure. In other words, your Apple ID is important. If you don't use two-step verification enabled — and you really should! — if you forget your password, the only way to reset it is with your security questions. That's why it's a good idea to review your security questions, make sure they're easy to remember for you but not easy to guess for anyone else.
How to change or update your iCloud login security questions
In any web browser — including mobile Safari — go to http://appleid.apple.com
Click on Manage your Apple ID in the right hand column.
Log in to your Apple ID using your current username and password.
Once logged in, click on Password and Security in the left-hand column.
Choose new security questions and type in answers you will remember.
Click on Save at the bottom.
That's it, you're done. Even though good secret questions may be able to keep out some unwanted characters, they still aren't fool proof. We highly recommend using two-step verification instead of secret questions altogether.
