Backup BitLocker Recovery Key in Windows 10

How to Backup BitLocker Recovery Key for a Drive in Windows 10

When you enable BitLocker for a fixed or removable data drive, you can configure it to ask for a password to unlock the drive. Also, BitLocker will automatically create a special recovery key. Recovery keys can be used to restore access to your files if you forgot your password for a removable or fixed drive, or if the system drive is encrypted using BitLocker, and BitLocker fails to unlock the drive on startup.

This means that if you lose your recovery keys for BitLocker protected drives, you won't be able to decrypt your data. That's why it is important to back recovery keys for BitLocker.

BitLocker was first introduced in Windows Vista and still exists in Windows 10. It was implemented exclusively for Windows and has no official support in alternative operating systems. BitLocker can utilize your PC's Trusted Platform Module (TPM) to store its encryption key secrets. In modern versions of Windows such as Windows 8.1 and Windows 10, BitLocker supports hardware-accelerated encryption if certain requirements are met (the drive has to support it, Secure Boot must be on and many other requirements). Without hardware encryption, BitLocker switches to software-based encryption so there is a dip in your drive's performance. BitLocker in Windows 10 supports a number of encryption methods, and supports changing a cipher strength.

Note: In Windows 10, BitLocker Drive Encryption is only available in the Pro, Enterprise, and Education editions. BitLocker can encrypt the system drive (the drive Windows is installed on), and internal hard drives. The BitLocker To Go feature allows protecting files stored on a removable drives, such as a USB flash drive.
