What Does "Encrypt iPhone Backup" Mean?
By Terry Parker
Whenever you connect your iPhone to your computer and sync it with iTunes, the phone’s contents are automatically backed up either to iCloud or to the computer. Backing up to the computer includes an option to encrypt the backup, which requires establishing a password. The result is that backup data is stored in an encrypted format that is unreadable unless you have the password to unlock it. If your computer is ever lost or stolen, your iPhone backups will be secured with a password. You won’t need to enter the password every time you sync your iPhone, but you must enter the password to access the backup data or restore an earlier backup.
Encrypt your iPhone Data
Open the iTunes application on your computer.
Attach your iPhone to your computer using a USB sync cable.
Click the iPhone name toward the top of the window.
On the “Summary” tab under Backups, click the “This Computer” radio button (if it isn’t already selected) and click the “Encrypt iPhone Backup” checkbox.
Type a password in the resulting password dialog box and retype it when prompted.
Click the “Set Password” button. The iPhone backup data is now password-protected.
