Security, How to encrypt Windows Mobile devices

This page provides instructions on how to encrypt a Windows Mobile device.

WARNING: When encrypting a device, it is imperative that you remember the password/PIN used to encrypt the device. If you forget the password/PIN, all data on the device will be lost.

Device encryption is an option that comes disable by default, but you can easily enable the feature using the following steps:

  1. While in the Start screen, swipe left to bring All apps, then search for and open the Settings app, and tap on System.

  2. Next, tap on Device encryption.

  3. Finally, make sure to slide the Device encryption pill switch to the On position to enable the feature.

Important Note: A password PIN must be in place to enable the feature if your mobile device doesn't have one when trying to enable Device encryption, you will be automatically redirected to the Sign-in options settings page to create a PIN. Then you would just tap the Add button, under the PIN section, and follow the on-screen wizard to create a new PIN. After the PIN password is created, you can go back to Device encryption settings to verify that the feature has been enabled.

While the feature should work as expected, Windows Phone 8.1 used to display an "encrypted" label in the phone storage settings, and Windows 10 Mobile doesn't provide such visual confirmation in the storage settings. The only way to verify your device is being encrypted is by making sure the "Device encryption" is turned on in the Settings app.

It's important to point out that while encryption is enabled on your mobile device, the operating system and your data stored in the local storage will be encrypted, but device encryption will not encrypt data that you stored on an SD card. As such, it's highly recommended that you not save sensitive data on a removable storage, as anyone could easily remove the storage and have unrestricted access to that data from any computer.

Furthermore, you need to be careful when to choose to enable this feature, as it's possible that encrypting your device may cause some issues, such as problems with emails not synchronizing with your phone.
