BitLocker recovery process
Finding your BitLocker recovery key in Windows
Quote
There are several places where your recovery key might be, depending on the choice that was made when activating BitLocker
- Attached to your Microsoft account
- Attached to your work or school account
- On a printout if you printed your recovery key when BitLocker was activated
- On a USB flash drive
You can also find the BitLocker Recovery Key in your Cloud storage OneDrive account or look for a BitLocker Recovery Key.txt or .pdf file which you may have saved on the computer or somewhere else and forgotten about.
If the device was set up or BitLocker protection was activated by another user, the recovery key may be in that user’s Microsoft account.
