Passwords are a thing of the past. You may log in using your face on select machines running Windows 11. You may have noticed this on your smartphone or on certain Windows 10 PCs. It's one of the quickest methods to log in to your smartphone safely. This is known as Windows Hello by Microsoft, and it may also be used to set up fingerprint readers.

The key need is that your PC's camera, such as those equipped with Intel's RealSense 3D technology, enable Windows Hello facial recognition. The camera must be able to scan your face by measuring its depth and monitoring its position. You have two alternatives if you don't already have a suitable camera:

1. You may buy a camera that works with your desktop PC monitor.

2. You may get a laptop or an all-in-one computer with an integrated camera that meets your needs.

3. Intel has a RealSense overview website as well as a more comprehensive RealSense page, both of which can direct you to various RealSense 3D cameras. However, several other manufacturers, such as Logitech, provide Windows Hello-compatible cameras. Microsoft's Windows 11 Computers website has a list of compatible laptops and other computers with built-in Windows Hello cameras.

4. The best location to see if your existing camera is supported is the same area where you set up face recognition. Open Settings in Windows 11 and go to the Accounts section. Click the Sign-In Options setting on the Accounts page. Look for the Windows Hello Face option. "This option is presently unavailable," says a warning if your camera doesn't pass the test. "Sign in using your camera," the notification reads if your camera is compatible. If this is the case, click the message and then the Set Up button (Figure A).

Click the Get Started button in the first Windows Hello window. Before you can set up any other kind of Windows Hello authentication, you must first enter your PIN. While your camera is being scanned, look at it and keep your face still (Figure B).

If the scan is successful, the following page informs you that you're good to go and that you may unlock your smartphone with your face the next time. Close the window by clicking the button (Figure C).

The camera's sensor should begin flashing while you're at the Lock Screen the next time you need to log in to Windows or unlock your PC. Simply look into the camera, and Windows should recognise you and sign you in using your face.

Return to the Windows Hello Face option in Settings if the face recognition isn't working or if your facial look changes in any way (glasses, beard, etc.). Select the choice and then click the Improve Recognition button (Figure D). You should be good to go after clicking the Get Started button, entering your PIN, and allowing the camera to scan your face.

Hello PIN is a heritage feature that is accessible in both Windows 10 and Windows 11. This gearupwindows post will assist you in using a secure PIN (Personal Identification Number) instead of passwords to log into a Windows 11 system.

If you don't want to use a password to log in to your computer, Windows 11 allows you to use a PIN instead. The PIN is a Microsoft-recommended technique for logging in to your Windows device that is both quick and safe. Other sign-in choices are enabled by the PIN, which is part of Windows Hello security. To login into Windows 11, you may use a photo password, PIN, fingerprint sensor, or even face recognition for your information alone.

If this sign-in option does not enable you to sign in using a fingerprint (the most secure way to enter into Windows if your PC has a fingerprint sensor), you may use Hello PIN to safeguard login.

The PIN is ineffective on other devices and only works on the one you established. If you use a Microsoft account to get onto a Windows 11 PC, your password can be stolen and used on any device with the same account. If you've created a PIN, though, it's unique to the device you've created. That implies you can't use a PIN to login in to another computer using the same account.

Even though your computer or laptop is connected to the internet, this feature of Windows 11 allows you to keep your account safe.

Microsoft has included face recognition setup into the out-of-the-box setup procedure in Windows 11. If you buy a new laptop with an infrared camera that supports Windows Hello face recognition, the first time you switch it on, you'll be prompted to set it up.

However, if you missed the setup process, upgraded from a Windows 10 PC, or even purchased a fancy new external camera that supports Windows 11, you may wish to do it later.

Here's how to enable face authentication in Windows 11:

1. Go to Settings and choose Accounts from the left-hand sidebar.

2. Select "Sign-in choices" from the drop-down menu.

3. Select "Facial recognition (Windows Hello)" from the drop-down menu and then "Set up."

4. A setup window for Windows Hello will open. To begin, select "Get started."

If you've set up a PIN, you'll be prompted to enter it immediately.

5. Take a good look at the camera. It will be scanning your face.

If you haven't already done so, Windows 11 will ask you to do so. You won't be able to do anything about it.

6. To complete the configuration, click "Close."

You may select "Improve recognition" to perform the scan again for a different look (for example, with or without spectacles).

Your computer will scan for your face the next time it goes to the lock screen, whether you locked it, it locked itself while sleeping, or you shut it off and turned it back on. The computer will unlock and take you to the Windows 11 desktop once it has been recognised.
