What Is a Microsoft BitLocker Recovery Key?

When BitLocker encryption is enabled on a Windows device, it automatically generates a unique 48-digit numerical code known as the BitLocker recovery key. This key serves as a backup unlocking method when BitLocker detects a potential security threat. These threats include hardware changes, BIOS updates, or boot issues.

The BitLocker recovery key ensures that only authorized users can access encrypted files, even if the computer is stolen or compromised. For devices linked to a Microsoft account, Windows may automatically save the recovery key to your Microsoft BitLocker Recovery Keys page, making it accessible online whenever needed.

How to Find Your BitLocker Recovery Key from Microsoft Account?

If you set up BitLocker while signed in with a Microsoft account, there’s a good chance your recovery key was automatically backed up online. The Microsoft BitLocker recovery keys page allows you to view and download them easily from any trusted device. Here’s how to find your BitLocker recovery key from your Microsoft account step by step:

  • Use another computer to go to your Microsoft Account and log in with your credentials.

How to Use the Microsoft BitLocker Recovery Key to Decrypt the BitLocker Drive?

  • Press Windows + R to open the Run box. Type control and press “Enter” to open Control Panel.

  • Go to “System and Security > BitLocker Drive Encryption”.
