BitLocker Drive Encryption is a critical security feature in Windows that protects data on lost or stolen computers by encrypting the drive. However, what happens when a user forgets their PIN, changes their motherboard, or triggers a security lockout? This is where the BitLocker Recovery Key comes in.
By storing BitLocker recovery keys in Active Directory, organizations can enhance the security and management of their encrypted data, ensuring that recovery keys are safely stored and easily retrievable when needed.
Before configuring your environment, ensure you meet the following hardware and infrastructure requirements: bitlocker recovery key active directory
If an attacker compromises Domain Admin rights, they can query all BitLocker recovery keys for all computers. This effectively neutralizes BitLocker's protection against offline attacks. For high-security environments, this requires additional controls (e.g., separating recovery key storage or using a Hardware Security Module).

Unlike consumer storage (Microsoft Account), AD escrow works with all BitLocker authenticators: TPM-only, TPM+PIN, TPM+USB, or password protectors. The recovery password is always escrowed regardless of the unlock method. By storing BitLocker recovery keys in Active Directory,
Computers must have a Trusted Platform Module (TPM) version 1.2 or newer, enabled in the BIOS/UEFI. Infrastructure: A Windows domain with Active Directory.
