Where BitLocker stores your recovery key

Windows stores your BitLocker recovery key in one of four places, and which one depends on how you set up encryption. The most common location is your Microsoft account — if you signed in with your Microsoft email when you turned on BitLocker, the key is saved there automatically. The second most common is a USB drive you created during setup. The other two are a text file saved to a folder on your computer (less common now) or printed on paper you kept somewhere safe.

The recovery key is a 48-digit number that looks like this: 111111-222222-333333-444444-555555-666666-777777-888888. You will need the exact number, with or without the hyphens, to unlock your drive if you forget your password or your computer won't start normally.

Key Takeaways

  • Your recovery key is most likely saved to your Microsoft account if you turned on BitLocker while signed in with your Microsoft email.
  • You can retrieve it from your Microsoft account online without needing to unlock your computer first.
  • If you set up BitLocker with a USB drive, that drive contains a copy of the key and can unlock your computer.
  • If you cannot find the key anywhere, you will need to contact Microsoft support or reset Windows, as there is no way to decrypt the drive without it.

Retrieving your key from your Microsoft account

Go to account.microsoft.com in a web browser on any device and sign in with the Microsoft email you use on your locked computer. Once you are signed in, look for "Security" or "Device security" in the left menu, then select "BitLocker" or "Encryption keys".

You should see a list of your devices. Find the computer you are locked out of and click on it. The 48-digit recovery key will appear on the screen. Write it down or copy it to a text file — you will need to type it into your computer to unlock the drive. If you do not see your device listed, it means the key was not saved to your Microsoft account, and you will need to check the other locations.

Checking a USB drive for the recovery key

If you created a USB recovery key during BitLocker setup, that drive contains a file called "BitLocker Recovery Key" or a text file with a name like "BitLocker-RecoveryKey-[your computer name]". Plug the USB drive into your locked computer (or into another computer if your locked one will not start). Open the drive in File Explorer and look for this file.

Open the file with Notepad or any text editor. Inside you will find your 48-digit recovery key. If the file is there, you can use this key to unlock your drive. If the USB drive is lost or the file is not on it, move on to the next location.

Looking for a saved text file on your computer

If you saved your recovery key as a text file on your computer before you were locked out, you will need to access it from another device or from Windows recovery mode. This is only possible if your computer will still start up — if it will not start at all, you cannot reach files this way.

If your computer starts but you cannot log in, restart it and press F8 or Shift+F8 repeatedly as it boots to enter recovery mode. From there, you can sometimes access a command prompt or file recovery tools. However, this method is technical and often does not work. If you have access to another computer, check whether you emailed the key to yourself or saved it to OneDrive or another cloud service.

What to do if you cannot find the key anywhere

If you have checked your Microsoft account, looked for a USB drive, and cannot find a saved file, you have two options. The first is to contact Microsoft support directly — they can sometimes help you recover access if you can prove you own the device. Be prepared to provide your device serial number and proof of ownership.

The second option is to reset Windows using the recovery tools built into your computer. This will erase everything on your drive but will allow you to set up Windows fresh. To do this, restart your computer and look for a "Reset this PC" or "Troubleshoot" option on the boot screen. This is a last resort because you will lose all your files, but it is the only way forward if the recovery key is truly gone.

Preventing this problem in the future

Once you regain access to your computer, take steps to make sure you do not lose the recovery key again. The safest method is to print a copy and store it in a physical location you will remember — a safe, a filing cabinet, or a drawer at home. Do not store it only on your computer or only in one online account.

You can also save the key to a USB drive and keep that drive separate from your computer. If you use OneDrive or another cloud service, save a copy there as well. The goal is to have the key in at least two places that are not your locked computer. Check your Microsoft account settings periodically to confirm the key is still saved there.

Frequently Asked Questions

Can I unlock my computer without the recovery key?

No. BitLocker is designed so that without the recovery key, there is no way to decrypt the drive. Even Microsoft cannot unlock it for you. Your only options are to find the key or reset Windows entirely, which erases everything.

What if I remember part of the recovery key but not all of it?

A partial key will not work — you need all 48 digits. However, if you remember enough to narrow down where you might have saved it, that can help. For example, if you remember creating a USB drive, focus on finding that drive. If you remember your Microsoft account, check there first.

Can someone else retrieve my recovery key from my Microsoft account?

No, not without your password. Only you can sign into your Microsoft account and view your recovery keys. If someone else has your password, change it when ready after you regain access to your computer.

Is the recovery key the same as my Windows password?

No. Your Windows password is what you type to log in. The recovery key is a separate 48-digit code that unlocks the encrypted drive itself. You need the recovery key only if you cannot log in normally or if your computer will not start.

How long does it take to get help from Microsoft if I contact support?

Response time varies depending on your support plan and how busy they are. It can take anywhere from a few hours to several days. If you need access to your computer urgently, searching for a USB drive or checking your Microsoft account will be faster.
