What is BitLocker?
BitLocker is Microsoft’s full disk encryption feature built into Windows Pro and Enterprise editions. It protects your data by encrypting entire volumes and requires a password, PIN, or USB key to unlock.
But if the password is forgotten, recovery depends on a BitLocker recovery key, often saved to a USB drive.
🛠️ Tutorial: Reset BitLocker Password Using USB Recovery Key
📌 Requirements:
- USB drive containing your BitLocker recovery key (
.BEKfile or recovery key ID) - Administrator access
- The encrypted drive must be connected
🧭 Step-by-Step Instructions
🔹 Step 1: Insert the USB with Recovery Key
Plug in the USB drive that contains your BitLocker recovery key into the locked computer.
🔹 Step 2: Boot or Access the Locked Drive
If the OS is locked:
- You will see the BitLocker Recovery screen at boot.
- Your USB should be automatically detected, and the drive will unlock if the recovery key is valid.
If you’re logged in but want to reset the password:
🔹 Step 3: Open Command Prompt as Admin
Press Windows + X > Command Prompt (Admin) or Windows Terminal (Admin).
🔹 Step 4: Identify the Drive
manage-bde -status
Note the drive letter of the BitLocker-encrypted volume.
🔹 Step 5: Reset the Password
Now use the following command:
manage-bde -protectors -add D: -password
Replace D: with your encrypted drive letter. You will be prompted to enter a new password.
🔹 Step 6: Remove the Old Password (Optional but Recommended)
To remove the old forgotten password:
manage-bde -protectors -delete D: -type Password
The above BitLocker management command used in Command Prompt (Admin) to remove a specific type of key protector in this case, a password—from a BitLocker-encrypted drive.
Step 7: Confirm the Changes
Run:
manage-bde -status D:
You should see the new password listed as a key protector.
Best Practices After Resetting
Backup the new password and recovery key securely (preferably to multiple secure locations).
Consider storing the recovery key in your Microsoft Account or Active Directory (for enterprise users).
Enable two-factor unlock (e.g., PIN + USB) for higher security.
