Windows Hellofacial recognition lets you sign in to a Windows 11 PC with your face instead of a password. It uses an infrared (IR) camera sensor to map your facial features and to block attempts to unlock the computer with a photo or video.
The feature needs a PC with built-in infrared hardware or an external Windows Hello-certified USB camera. A standard webcam will not work, because it lacks the near-infrared sensors Windows needs. If the Facial recognition (Windows Hello) option is greyed out or missing later in this guide, missing hardware is the most likely reason.
So should you turn it on? For most people with a compatible laptop, yes, as long as you keep a PIN as a backup. It is faster than typing a password and harder to fake than a photo-based login. This guide covers setup, tuning, removal and fixing common problems.
⚡ Quick Answer
Yes, if your PC has an infrared camera or a Windows Hello-certified USB camera. Open Settings, select Accounts, then click Sign-in options and Facial recognition (Windows Hello) to set it up. A standard webcam will not work, and the option stays greyed out without compatible hardware. Keep your PIN as a backup sign-in method.

How to Set Up Facial Recognition in 🪟 Windows 11
Setting up Windows Hello facial recognition takes about two minutes. You scan your face once, and Windows also asks you to create a PIN, which becomes your fallback sign-in method. The steps below are for Windows 11 and are the same on Home and Pro.
📝Good to KnowCheck the hardware first. Facial recognition needs a compatible IR camera, either built into the PC or plugged in as a certified external unit. Without one, the face option does not appear in Settings, and no setting can add it.

If your PC has no compatible camera, Sign-in options may still offer other Windows Hello methods. Fingerprint recognition and security keys (small physical devices that prove who you are) work as alternatives where the facial recognition hardware is missing. Fingerprint recognition needs a fingerprint reader on the PC.
Open Settings by pressing Win+I, or by pressing the Win and clicking the gear icon. The Settings⚙️ window opens.
Windows 11 Start menu with Settings gear icon highlighted.
Select Accounts from the left-hand navigation menu.
Settings › Accounts
Click Sign-in options. A list of sign-in methods appears.
Settings › Accounts › Sign-in options
Click Facial recognition (Windows Hello) to expand the section. If it is greyed out or missing, Windows has not detected a compatible infrared camera.
Click the Set up button to launch the configuration wizard, then click Get started.
Type your current PIN when prompted to verify your identity. If you have no PIN yet, Windows asks you to create one first. Sign in with an administrator account or provide your account password to continue.
Position your face directly in front of the camera, inside the on-screen frame. Hold still while the sensor captures your facial features. Take off glasses or a hat only if the wizard has trouble reading you.
Click Close once the setup wizard confirms the scan was captured successfully.
Lock your PC with Win+L and look at the camera. Windows should sign you in without any typing.
That’s it. Facial recognition is now active, and your PIN stays available as a backup. No restart is needed.
Choosing Between Multiple Viable Facial Recognition Devices
If more than one camera or sensor is connected, for example a built-in infrared camera and an external USB camera, Windows needs to know which one to use for signing in. Choosing the right device stops it from trying a camera that cannot do facial recognition.
Click Facial recognition. The face settings expand.
Facial recognition set up
Locate the dropdown menu or selection list labeled Select your preferred Hello device. This setting normally appears only when more than one compatible device is connected.
Choose your primary infrared camera or external sensor from the available hardware options. The change applies at your next sign-in, so lock the PC and test it.
You should now have the correct camera set for face sign-in. If the setting never appears, only one compatible device is connected, and Windows already uses it.
Improving Facial Recognition Accuracy in Different Lighting Conditions
If Windows sometimes fails to recognize you in dim rooms, bright sunlight, or after a haircut, beard change or new glasses, run the improvement wizard. It adds more facial data to your existing profile rather than replacing it.
Microsoft’s notes for Windows 11 25H2 say face and fingerprint sign-in with Windows Hello are getting faster and more reliable. These improvements are rolling out gradually, so install pending updates through Windows Update as well.

Open Settings and navigate to Accounts.
Click Sign-in options.
Select Facial recognition.
Click the Improve recognition button to launch the enhancement wizard.
windows 11 improve recognition facial
Enter your PIN to confirm your identity.
Follow the on-screen prompts while sitting in your typical lighting environment. This adds supplementary facial data. If the problem is a specific setting, such as a dark room or a bright window behind you, run the wizard again there.
That’s it. Your saved face profile now includes the extra scan, and recognition should be more reliable in that setting.
Depending on your Windows 11 build, the same section may also offer an Automatically improve recognition option. When it is on, Windows refines your saved face data over time as you sign in. If you do not see it, your build does not include it, and the Improve recognition button still works.
Scroll down to the additional settings in Sign-in options to control how face sign-in behaves. One is If you’ve been away, when should Windows require you to sign in again?, which sets how long the PC can sit idle before it asks for credentials. Another is the option to require Windows Hello sign-in for Microsoft accounts on the device. The exact wording of these settings varies between builds, and some may be missing on a work or school PC managed by an organization.

How to Remove or Reset Your Windows Hello Face Data
Remove your face data if you keep getting recognition errors, want to start clean, or plan to sell or hand over the device. This deletes your biometric profile from the computer. It does not delete your PIN or password.
⚠️WarningThe removal is permanent for the stored scan, so you cannot restore it. You can only register a new one.
Open Settings and navigate to Accounts.
Select Sign-in options.
Click Facial recognition.
Click the Remove button next to the recognition profile to delete your stored biometric data permanently.
Face sign-in stops working straight away in Settings, and you will use your PIN or password instead.
Re-run the setup wizard if you want to register a fresh facial scan. That is also how you undo the removal.
That’s it. Your face data is gone from the PC, and you sign in with your PIN or password until you set up facial recognition again.

Enhancing Security with Enhanced Sign-in Security
Enhanced Sign-in Security protects your login credentials from hardware-level attacks by pairing your biometric hardware with virtualization-based security features. It is a hardware-dependent feature and is not available on every PC.
Check the requirements before you look for the toggle. The PC needs to be a Secured-core or otherwise compatible system, with a supported chip and a compatible camera or fingerprint sensor. The hardware, firmware and drivers must all support the feature. The option appears under Windows Security›Device security›Core isolation only on supported systems.
It also needs current drivers from the manufacturer for Windows 11 version 25H2 or 26H2. Windows 11 24H2 Home and Pro stopped receiving updates on October 13, 2026, so update those editions before you look for the option. Without all of these, the option does not appear.
Open Windows Security by searching for it in the taskbar🖥️search box🔍. You can also go to Settings›Privacy & security›Windows Security.
Locate Enhanced Sign-in Security and switch the toggle to On. This feature requires compatible motherboard hardware, a supported CPU, and specialized drivers provided by your system manufacturer. If you cannot find the option, your PC most likely does not support it, and there is nothing wrong with your setup.
Restart your🔄 computer to apply the security changes.

You should now have Enhanced Sign-in Security running after the restart, with your face data protected by the extra hardware-level layer.
If your PC does not support this feature, facial recognition still works. It only lacks the extra hardware-level protection. To undo the change, switch the toggle back to Off and restart.
Troubleshooting Common Windows Hello Camera Errors
Camera errors usually mean Windows cannot turn on the infrared sensor, or it reports that it cannot find a compatible camera. A missing, outdated or broken driver (the software that lets Windows talk to the hardware) is the most common cause, so start in Device Manager.
Open Device Manager by right-clicking the Start button and selecting it from the menu.
Expand the Cameras or Biometric devices category. The infrared camera is often listed separately from the normal webcam.
Right-click your infrared camera driver and select Update driver.
Choose Search automatically for drivers to let Windows find and install the💿 latest software package. If Windows says the best driver is already installed, check your PC manufacturer’s support page for a newer one.
Restart your🔄 computer if the driver update completes successfully. Then check Sign-in options again to see whether Facial recognition (Windows Hello) is available.

That’s it. If the driver was the problem, the face option now appears in Sign-in options, and you can run setup.
What to do next
Windows Update is another common source of camera and biometric drivers. Check it if Device Manager finds nothing newer.
Go to Settings›Windows Update🔃›Advanced options›Optional updates.
Expand Driver updates.
Select any camera or biometric driver that is listed, then click Download & install.
Restart afterward if Windows asks.
You should now have the latest driver Windows offers for the sensor. If nothing is listed under Driver updates, no newer driver is available through Windows Update.
If the driver update does not help, test the camera in a video app such as the Camera app. This rules out a physical obstruction, a privacy shutter or a camera switch that is turned off. Keep in mind that the normal webcam may work while the infrared sensor does not.
Still stuck? Open Settings›Accounts›Sign-in options and look for the Fix problems option in the face section. It leads to the Get Help app, which walks you through further checks. Availability of this link can vary by build.
Always keep a backup sign-in method, such as a PIN or fingerprint, so you cannot get locked out if facial recognition fails. For everyday use, face sign-in plus a strong PIN is a good balance of speed and security. Be a little more cautious on a shared PC, or if someone could hold the device up to your face while you are asleep. In those cases, a PIN or a fingerprint may suit you better.
Frequently asked questions
What are the limitations of Windows Hello?
Windows Hello facial recognition requires a PC with an infrared camera—standard webcams don't work. It won't function in poor lighting. You need to set up a backup sign-in method like a PIN or password. Some people find setup takes multiple attempts if the camera doesn't capture their face clearly.
How does Face ID know it's me?
Windows Hello maps your unique facial features using infrared light, creating a mathematical model of your face. It compares your live face to this stored model each time you sign in. The infrared camera sees through photos and videos, so it can't be fooled by a picture or screen recording of your face.
Is it better to use fingerprint or face ID?
Fingerprint is faster and works in any lighting. Face recognition is more convenient—you don't touch anything. Neither is objectively better. Choose based on your PC setup: fingerprint if your device has a reader, facial recognition if you have an infrared camera. Many people use both as backup methods.
What is the difference between Windows Hello and Face ID?
Face ID is Apple's facial recognition system for iPhones and iPads. Windows Hello is Microsoft's equivalent for Windows PCs. Both use infrared cameras to map faces securely. The main difference is the company and device—Face ID for Apple, Windows Hello for Windows machines.
