Windows Hello lets you sign into your computer using your face, a PIN, or your fingerprint. One cool security feature is called anti-spoofing, which helps stop fake faces or photos from unlocking your PC.

This guide will show you simple steps to turn on or off the anti-spoofing feature for Windows Hello face sign-in on Windows 11.

What Is Anti-Spoofing?

Anti-spoofing is a security tool that makes facial recognition smarter. It helps your computer tell if someone is trying to trick it with a photo or mask instead of your real face.

Note: Turning on enhanced anti-spoofing can sometimes make it harder to sign in if your device doesn’t support it well.

How to Turn On or Off Anti-Spoofing Using Windows Settings

   • Click the Start menu and select Settings,
     
     or
   • Press Windows key + I on your keyboard.
2. Click Accounts on the left side menu.
3. Click Sign-in options on the right.
4. Find Facial recognition (Windows Hello) and click to expand it.
5. Check or uncheck the box next to “Enhanced facial recognition protection” to turn anti-spoofing on or off.
6. Click Restart now if your PC asks you to restart.
