It’s a good practice to create a backup of your iPhone in iTunes in case you accidentally delete your iPhone data. One important problem with iTunes backup is that it’s not encrypted by default. If you create a local backup stored on a computer, your backup could be accessed by anyone who has physical access to your computer. To prevent data leakage or data loss, I would recommend you encrypt your iTunes backup with a password.

How to Encrypt Your iTunes Backup with Password?

1. Connect your iPhone to a computer (or Mac) with iTunes installed. Launch iTunes and then click on the little iPhone icon in the upper toolbar. This takes you to the Summary page.

   

2. Under the Summary page, you will see a section called Backups. Check This computer and also check Encrypt iPhone backup checkbox.

   

3. You will be asked to create a password that will used to encrypt your iTunes backup. Make sure you set a good password you won’t forget.

   

   If you’re running Mac OS X, there is an additional option lets you save the password in Keychain access, and I don’t suggest you ticking that option.

4. Once you clicked the Set Password button, iTunes will encrypt all your local backup immediately.

   

5. When it’s done, you can verify that your backup is encrypted. Within iTunes, click the Edit menu and select Preferences.

   

6. Once the Preferences window opens, click the Devices tab. If you spot a tiny lock icon in the row of your latest backup, it indicates your iTunes backup is encrypted successfully.

   

After encrypting your iTunes backup with a password, nobody can restore a device from the backup without knowing your password. The data in the backup is encrypted too, and no need to worry about data leak even when your computer is stolen.
