BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers. It provides the most protection when used with a Trusted Platform Module (TPM) version 1.2 or later (2.0) as at the time of writing this guide. The TPM is a hardware component installed in many newer computers by device manufacturers. It works with BitLocker to help protect user data and to ensure that a computer has not been tampered with while the system was offline. Kindly refer to these related guides: How to clear, enable or disable TPM in Windows via the BIOS or UEFI, MBAM reports cannot be accessed because it could not load folder contents, BitLocker Drive Encryption architecture and implementation types on Windows,

On computers that do not have a TPM version 1.2 or later, you can still use BitLocker to encrypt the Windows operating system drive. However, this implementation will require the user to insert a USB startup key to start the computer or resume hibernation. Starting with Windows 8, you can use an operating system volume password to protect the operating system volume on a computer without TPM. Both option do not provide the pre-startup system integrity verification offered by BitLocker with a TPM.

Here are some relevant guides: How to enable or disable BitLocker Drive Encryption on Windows 10 and Virtual Machines, how to clear the TPM via the management console or Windows Defender Center App, and MBAM reports automatic E-mail notification: How to create MBAM Enterprise and Compliance, and Recovery Audit reports.

In addition to the TPM, BitLocker offers the option to lock the normal startup process until the user supplies a personal identification number (PIN) or inserts a removable device, such as a USB flash drive, that contains a startup key. These additional security measures provide multifactor authentication and assurance that the computer will not start or resume from hibernation until the correct PIN or startup key is presented.

Most times, these Recovery keys are saved to a USB, Active Directory, or the MBAM, etc just as you have configured it for your environment.
– Then, enter the password and click “Unlock” to unlock the drive. This 48-character recovery password will decrypt the drives, granting access to the volume.

If this device was to be procted by MBAM, you can get this key via the MBAM helpdesk, database, or selfservice recovery portal!
