Encrypting a Device

Overview

Encrypting data stored on your devices is critical to protecting the confidentiality and privacy of your data. In the event that your device is lost or stolen, encryption secures your data by making it extremely difficult for any unauthorized user to gain access to your files without knowing your passcode or password.

IMPORTANT NOTE: If you choose to encrypt your data, it is of utmost importance that you remember your passcode/password and, if applicable, save your recovery key in a safe place. If you forget your password and lose your recovery key, it is highly unlikely that your data will be recoverable. The device will need to be reset to factory settings which will erase all existing data.

Depending on how much data is stored on your device, the process can take a couple hours. It is best to encrypt your device when you will not be actively using it. Before you begin, make sure to plug in your device to power.
