iPhone Encryption: How to Encrypt your iPhone

Even if you don't think about it often - or not at all - you benefit from encryption every day. It protects your identity, the pictures of your family, your home WiFi network and your finances. If you are one of the 700 million iPhone users worldwide, everything on your smartphone is very likely encrypted as 95 percent of Apple phones are encrypted when the screen is locked.

This standard protection means that the data on the cell phone is safe from intruders. This is especially important when you are on the go, but your smartphone can be lost at any time. Therefore, you should definitely use encryption when the cell phone is not in use. Fortunately, it's not difficult to encrypt an iPhone with a few simple steps.

Determine the iOS version

The encryption on the iPhone has changed with iOS 8. So first check your iOS version: Open the “Settings” app on your mobile phone, select “General” and then “About”. The installed iOS version is displayed under "Version". In the “General” menu, you can also check the latest software updates to ensure that the latest version for the model is running on your smartphone. Keeping software up-to-date is an important part of keeping your phone safe.

Encryption in seconds

Personal data is encrypted by default on Apple smartphones if the mobile phone is locked by a code or a Touch ID. The menu option to enable this feature is in a different location depending on the iOS version.

For iOS 8 and later versions, you will find the “Touch ID & Code” menu under “Settings”. On iPhones with iOS versions prior to version 8, the code option is located in the “General” menu in the “Settings” app. If you haven't activated passcode or Touch ID, the program will guide you through the steps to protect your phone.

While the code is being set up, certain options on the iPhone allow you to determine how difficult it should be for someone to crack your phone. With some versions, access is via a fingerprint, the Touch ID. Security experts are experimenting with ways to bypass Touch ID, for example with plasticine or 3D printers. This method is therefore not as safe as originally thought.

As for the numeric code, longer and more complicated codes are more difficult to guess. You may need to enable the custom numeric code or the custom alphanumeric code and disable the simple code option. The setup program will warn you if your code is easy to guess.

Depending on how important the data on the smartphone is, you can choose to automatically delete it from the iPhone after a certain number of failed access attempts. This is a good idea for business smartphones and personal phones with sensitive health or financial information. However, the automatic erase function is an extreme measure that should be carefully considered, especially if small children occasionally play with your cell phone.

A safer alternative would be to remotely erase the content on the iPhone using your iCloud account if it is lost.

Don't forget to backup

The data on the smartphone is now safe. But you also have to make sure that the backups stored in iCloud or iTunes are also encrypted. An encrypted iPhone backup includes saved passwords, WiFi credentials, and other sensitive data that you need should your phone be lost, damaged, or stolen. Backups are automatically encrypted in the iCloud. On iTunes, select the option Encrypt iPhone backup under the backup settings for the respective device. You have to determine a new password for the iTunes backup.

The data on your phone is now safe. To keep it that way, you should regularly make backups of this data and check whether there are updates for iOS or apps. But even an encrypted iPhone is prone to software bugs and ransomware. With some proactive steps, e.g. For example, by using a mobile security solution, you can ensure that no important data is disclosed to cyber criminals and cell phone thieves.
