You can save information like passwords and website history in an iTunes backup if you encrypt it, which is an option that Apple offers. Encrypted backups are not the default option, but for those of you who want to be able to save more comprehensive backups to your computer, we've created a tutorial that walks you through encrypting iTunes backups and removing that encryption.
If you back up your iOS device using iCloud, you do not have to follow any steps for encryption, as iCloud backups are automatically encrypted for you.
- Connect your iOS device to your computer the way you normally do.
- Open iTunes if it doesn't open automatically when you connect your device and let your device sync normally.
- Select your device in iTunes. Then click "Summary."
- In the Backups section, check the box for "Encrypt iPhone Backup."
- You will be asked to create a password. Make sure it is something that you won't forget. You can remember the password in your keychain.
- iTunes will create a new full backup of your device's data and will also overwrite and encrypt previous backups.
- Wait for the backup to finish. Then, check to ensure that it was properly encrypted. Go to Preferences from the iTunes toolbar. Then select Devices. If the backup was encrypted, you will see a lock next to it.
If you decide not to use an encrypted backup anymore, you can disable it.
- Connect your iOS device to your computer and open iTunes.
- Select your device from the menu. Then click "Summary."
- Uncheck the box for "Encrypt iPhone Backup."
- Enter the password you created to enable the encrypted backup.
- Wait for the backup to finish.
