BitLocker is a tool in Windows 11 that protects your data by encrypting your drives. This means only you (or authorized users) can access the files on your encrypted drives.

When you use BitLocker on a drive, you can set it so the drive automatically unlocks when you sign in to your computer. This is called auto-unlock. It’s handy because you don’t have to enter a password every time, but it still keeps your data safe from others.

You can use auto-unlock on USB drives, external drives, or fixed drives (like a second hard drive inside your PC). This guide will show you simple steps to turn BitLocker auto-unlock on or off for your drives.

How to Turn On or Off BitLocker Auto-Unlock Using Control Panel

Follow these easy steps:

1. Click the Start button, type Control Panel, and open it.
2. Go to System and Security, then click BitLocker Drive Encryption.
3. Find the drive you want to change in the list (it will say “BitLocker On”).
4. To turn auto-unlock on, click Turn on auto-unlock next to that drive.
5. To turn auto-unlock off, if it’s already on, click Turn off auto-unlock.
   

Here’s what it looks like when you turn auto-unlock on for a fixed drive:

And here’s the screen when auto-unlock is turned off:
