BitLocker Password Reset

TL;DR

This guide shows you how to change your BitLocker password if you’ve forgotten it or need to update it. It covers using a recovery key and managing BitLocker from the Control Panel.

Changing Your BitLocker Password

1. Check If You Have a Recovery Key: Before attempting any changes, locate your BitLocker recovery key. This is essential if you forget your password.
   • If you saved it to your Microsoft account: Go to this link and sign in with the same account used when enabling BitLocker.
   • If you saved it to a file: Search your computer for files named ‘BitLockerRecoveryKey.bek’.
   • If printed, find the physical copy of the key.
2. Unlock Your Drive (if necessary): If prompted, enter your current BitLocker password to unlock the drive.
3. Access BitLocker Management: There are two main ways to manage BitLocker:
   • Control Panel Method:
     1. Open the Control Panel (search for ‘Control Panel’ in Windows search).
     2. Go to System and Security > BitLocker Drive Encryption.
     3. Find the drive you want to manage and click “Change password”.
     4. Follow the on-screen instructions to enter a new password.
   • Command Prompt Method (for advanced users):

     manage-bde -changepassword C:

     Replace ‘C:’ with the drive letter you want to change the password for. You’ll be prompted for your current and new passwords.

4. Enter New Password: Carefully type in a strong, memorable new password.
   • Confirm the password to ensure it matches.
5. Restart Your Computer (if prompted): Some changes may require a restart for them to take effect.

Recovering Your BitLocker Password

1. Enter Recovery Key: If you’ve forgotten your password, Windows will prompt you to enter the recovery key.
   • Copy and paste (or type) the 48-digit recovery key into the provided field.
   • Be careful when entering the key; incorrect entries may lead to data loss.
2. Create a New Password: After successfully entering the recovery key, you’ll be prompted to create a new password.
   • Choose a strong and memorable password.
   • Confirm the password.

Important Considerations

• Back Up Your Recovery Key: Always store your recovery key in multiple secure locations (Microsoft account, file, printed copy).
• Strong Passwords: Use strong passwords that are difficult to guess. Consider using a password manager.
• Regular Password Changes: Change your BitLocker password periodically as a security best practice.
