Keep answers phone-friendly
Remember that you could wind up in a situation where you have to supply these answers over the phone. Both you and the person on the other end will have an easier time coping with a series of plain-English words than with a bunch of random characters.
Update your Apple info
To change the questions or answers for an Apple ID (which you use for iCloud, for example), go to the Apple ID page (appleid.apple.com), click Manage your Apple ID, enter your username and password, and click Sign in. On the left, choose Password and Security. Answer your existing security questions, and click Continue. Then you can choose new questions and answers. Click Save.
Update your Google info
If you have a Google account, log in as you normally would. Click the gear icon located in the upper-right corner of the window and choose Settings from the pop-up menu. Click Accounts and Import, followed by Change password recovery options. Under Security question, click Edit. Choose one of the existing questions or write your own, and fill in your answer. If you also want to change your secondary address, click the Edit link in the 'Recovery email address' section and fill in the new address. Then click Save.
