Mobile platforms like Android and iOS have built-in encryption. For iPhones, a simple trip to settings, then Touch ID and Passcode, and Passcode Options will allow you to select a numeric or alphanumeric code for the device. For Android, the process can be completed by navigating to Settings, then to Security, then to Encrypt Phone, and finally, you’ll need to set a numeric code. On Android, the process is extensive and may take up to an hour – be sure to keep your phone plugged in.
