BitLocker is a tool in Windows 11 that helps keep your files safe by locking your computer’s main drive. This means only you (or someone with the right info) can open your computer and see your data.

By default, if your computer has a special chip called TPM (Trusted Platform Module), BitLocker will unlock your computer automatically when it starts. But for extra safety, you can set it up so you need to enter a PIN and plug in a USB drive with a special key before your PC will start.

This guide will show you simple steps to set this up.

Step 1: Turn On BitLocker

2. Go to System and Security > BitLocker Drive Encryption.
3. Click on Change how drive is unlocked at startup.
4. Click Enter a PIN (recommended).
5. Type a PIN with 6 to 20 numbers, then confirm it by typing it again.
6. Click Set PIN.

Step 3: Require a USB Drive to Unlock BitLocker

1. Open the Control Panel again if it’s closed.
2. Go to System and Security > BitLocker Drive Encryption.
3. Click Change how drive is unlocked at startup.
4. Click Insert a USB flash drive.
5. Plug in a USB flash drive. This will save a special key on your USB.
6. Click Save.

What If You Want to Stop Using PIN or USB to Unlock?

If you decide later that you don’t want to use the PIN or USB key, you can change BitLocker back to unlock automatically with TPM only. Check out this guide:
