If no BitLocker recovery key appears in the Microsoft account, the key was not saved there or BitLocker was activated under a different account or by an organization.
Check these supported locations:
- Another Microsoft account
If the device was first set up with a different personal account, the recovery key might be attached to that account instead. - Work or school account
If the device is managed by work or school, the recovery key is typically backed up to the organization. It can be available throughhttps://myaccount.microsoft.comunder Devices > View BitLocker Keys, or through the Intune Company Portal if the organization allows it. - Printed copy or USB/file backup
When BitLocker was enabled manually, the person who enabled it chose where to save the recovery key. Check for a printout, a USB device, or a saved recovery key file. - Another person who set up the device
If someone else enabled BitLocker or originally configured the PC, the recovery key might be in that person’s Microsoft account or managed by their organization.
Important facts:
- A BitLocker recovery key is a 48-digit number.
- Microsoft Support cannot retrieve, provide, or recreate a lost BitLocker recovery key.
- If the recovery key cannot be found in any saved location, the encrypted drive cannot be unlocked.
If the device is a work or school PC and is enrolled in Intune, the recovery key can be retrieved from the Company Portal website:
- Sign in on another device
- Go to Devices
- Select the locked PC
- Select Get recovery key > Show recovery key
If no recovery key exists in any of those locations, the remaining option is to reset or reinstall Windows, which removes files on the encrypted drive.
