This guide will help you easily turn on or off the feature that automatically unlocks your PC when Windows Hello recognizes your face on the lock screen unlock in Windows 11.

What is Windows Hello?

Windows Hello is a secure and easy way to sign into your Windows 11 PC. You can use a PIN, your face, or your fingerprint. Setting up a PIN is required before you can use facial recognition or fingerprint sign-in, but you can always sign in using just your PIN.

Using Windows Hello makes signing in faster and safer because your PIN works only on your device and is backed up by your Microsoft account.

You can set up face sign-in using your PC’s built-in infrared camera or an external one.

Once you’ve set up facial recognition, you can decide if you want your PC’s lock screen to unlock automatically when it sees your face.

Option 2: Use Registry Editor (For Advanced Users)

Note: You need to be signed in as an administrator to do this.

2. Type this command and press Enter to see all user accounts and their IDs (called SIDs):
   

   Get-WmiObject win32_useraccount | Select name,sid

3. Find the SID for the user you want to change. It looks like this: S-1-5-21-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxx.
4. Open Registry Editor by typing regedit in the Start menu and pressing Enter.
5. In Registry Editor, go to:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\FaceLogon
   
6. Look for a folder (called a key) named with the SID you found earlier and click on it.
7. On the right side, double-click AutoDismissOn.
8. Change the value to 1 to turn on auto unlock, or 0 to turn it off, then click OK.
