Active Directory – How to display Bitlocker Recovery Key

When Bitlocker is enabled on workstation/ laptop in your entreprise, you must have a solution to get the recovery key of the hard drive. In some cases, Bitlocker can prompt to the user the Recovery key if it detects a specific behavior like partition changes.

The easiest solution is to use Active Directory Users And Computers console. This can only be possible if you set in the GPO to store Recovery Key into Active Directory.

With Active Directory Users And Computers, we can:

  • Display Bitlocker Recovery key for one computer.
  • Search in all Active Directory for a Password ID.
  • Delegate Rights to display confidential information.

Feature installation

Before searching your computer in Active Directory, you need to install a plugin to display Bitlocker Recovery Key information. It is integrated in features since Windows Server 2008.

To install Bitlocker Recovery Key feature:

  • Go to Server Manager.
  • On Features Page select Remote Server Administration Tools.
  • Check Bitlocker Drive Encryption Administration Utility.
    • Check Bitlocker Drive Encryption Tools.
    • Bitlocker Recovery Password Viewer.

Bitlocker Recovery Key Lookup Tool

Sometime, you don’t have the computer name because the remote user doesn’t know it. You only have first 8 digit code. Don’t panic, there is a solution for that too. 🙂

We can search for 8 digit code in all computer objects:

  • Right click on your domain name.
  • Select Find Bitlocker Recovery Password.
