What is device encryption?
Device encryption helps protect your data, and it's available on a wide range of Windows devices. If you turn on device encryption, the data on your device can only be accessed by people who've been authorized. If device encryption isn't available on your device, you may be able to turn on standard BitLocker encryption instead.
How to encrypt your Mac

- Click “Turn On FileVault…”
- IMPORTANT: Make a note of the recovery key that is displayed and store it away from your Mac.
- Wait for encryption to complete, but it’s OK to continue using the computer.
How to encrypt your Windows device
Note: BitLocker is not available on Windows 10 Home edition. Is it available on my device? Device encryption is available on supported devices running any Windows 10 edition. If you want to use standard BitLocker encryption instead, it's available on supported devices running Windows 10 Pro, Enterprise, or Education. Some devices have both types of encryption. For example, a Surface Pro which runs Windows 10 Pro has both the simplified device encryption experience, and the full BitLocker management controls. Not sure which version of Windows you have?
