BitLocker Dive Encryption Recovery Key Identifier Location & Identifier validity?

Question

Have a questions concerning where to look for the identifier associated with a BitLocker Recovery key and the actual accuracy of the KEY ID itself.

This is the info that appears when looking up the recovery key:

"To verify that this is the correct recovery key, compare the start of the following identifier with the identifier value displayed on your PC.

Identifier:

C1A8R900-aaaa-bbbb-cccc-xxxxxxxxxxxx

If the above identifier matches the one displayed by your PC, then use the following key to unlock your drive."

The above identifier is an example of the real sequence of characters presented when looking up the Recovery Key by logging into your account at https://aka.ms/myrecoverykey.

My question is: Where is this identifier value located? I've looked in Settings - System - About, and see 2 items:

Device ID - which has the same grouping sequence as above - but Device ID character string first 8 characters does not match the Recovery Key identifier.

Product ID - not even close

If the Recovery Key 'identifier value' is the Product ID in settings - why doesn't Microsoft say so in the supporting Recovery Key documentation? If the Product ID is not the correct ID, what is? Where do you look it up?

MOST IMPORTANT: If the Product ID found via Settings - System - About (that first group of 8 characters) does NOT match the KEY ID listed for the PC via the MS account BitLocker Recovery Keys what do you do fix this problem??

Thanks - any thoughts and suggestions are appreciated.

Answer 1

The Bitlocker ID is not found in the Settings App, to find the Bitlocker ID for a drive to match it with the Bitlocker Recovery Key on your account, open Command Prompt, then run this command (replace X with the drive letter).
