Your iCloud password protects the privacy of the information (such as your email) stored in iCloud. Your password also protects your ability to locate or remotely erase your device using Find My iPhone. You should regularly change your iCloud password to protect your information. Your iCloud password is the password for the Apple ID you use to sign in to iCloud.

Important: If you use the same Apple ID for iCloud as you do with other Apple services such as the Apple Online Store, iTunes Store, App Store, or to purchase products in iPhoto or Aperture, changing your iCloud password also changes your password for these services. Make sure you sign in to those locations using your new password.
