Accounts and Security
Windows Hello replaces typing a long password with a PIN, a fingerprint or your face, and it is more secure than it looks. This guide sets up the method you want, adds a fallback so you are never locked out, and covers locking the screen automatically.
Why A PIN
It looks like a downgrade and it is the opposite. The reason comes down to where each one can be used, and what happens if someone steals it.
Your account password works anywhere. If it is captured, whoever has it can sign in to your account from any machine on earth, and you would not know. A Windows Hello PIN is tied to the one physical device you set it up on. It is stored locally, protected by the security hardware in that machine, and it is worthless to anyone who does not also have the computer in their hands. Wrong guesses lock the device rather than opening it up to unlimited attempts.
Fingerprint and face sign-in work the same way underneath. The biometric data stays on the device, and what the reader really does is unlock the credential already held there. That is why Windows asks you to set a PIN before it lets you set up a fingerprint. The PIN is the foundation, and the fingerprint is a convenient way to satisfy it.
The habit that matters most is locking the screen when you walk away, which is the Windows key and L. Sign-in options make that painless, because unlocking costs you a second rather than a typed password. If you are setting up several machines for a small team, this is one of the things we configure as standard during new computer setup, alongside the rest of the security baseline.
Fingerprint readers fail, cameras stop being recognized after a driver update, and gloves exist. Set up a PIN as well as any biometric method so a hardware hiccup is an annoyance rather than a lockout.
Step By Step
Work through in order. The PIN comes first because Windows requires it before biometrics can be enrolled.
Press the Windows key and I for Settings, then go to Accounts > Sign-in options. The page lists every available method: Facial recognition, Fingerprint recognition, PIN, Security key, Password and Picture password. Anything your hardware does not support is grayed out with a short explanation.
Select PIN (Windows Hello) and choose Set up or Change. Confirm your account password when asked, then enter a PIN twice. Ticking Include letters and symbols lets you use a longer mixed PIN, which is worth doing on a laptop that travels. Avoid birthdays and repeated digits.
Select Fingerprint recognition (Windows Hello) and choose Set up. Lift and place the same finger on the reader repeatedly as prompted, adjusting the angle slightly each time, then repeat for the edges of the fingertip. When it completes, add a second finger from the other hand so an occupied hand is not a problem.
Select Facial recognition (Windows Hello) and choose Set up. Look at the camera while it builds the model, which takes a few seconds. If this option says your device does not support it, the camera is a standard webcam rather than an infrared one, and no setting will change that. Use Improve recognition afterward if you wear glasses sometimes.
Further down the same page, under Additional settings, find the option that asks when Windows should require you to sign in again after you have been away. Set it to When PC wakes up from sleep. On a machine that leaves the house, that setting is doing real work.
Pair your phone to the PC over Bluetooth first, through Settings > Bluetooth & devices. Then on the Sign-in options page, expand Dynamic lock and tick the box allowing Windows to lock the device automatically when you are away. The PC locks shortly after the paired phone moves out of range.
Press the Windows key and L to lock the screen. On the sign-in screen, select Sign-in options if it appears and check that you can get in with the PIN as well as the fingerprint or face. Testing this now is much easier than discovering the gap on a morning when the reader has stopped responding.
Worth Knowing
Encryption, shared machines and the small settings that decide whether any of this actually protects you.
Go to Settings > Privacy & security and look for Device encryption, or BitLocker on Pro editions. Encryption is what makes a strong sign-in meaningful, because without it the drive can be removed and read elsewhere. If you turn it on, make sure the recovery key is saved to your Microsoft account, because a lost key means the data is gone for good.
Windows key and L, every time you stand up. Sign-in options exist to make that cost nothing. All the biometric setup in the world does not help a machine left unlocked and unattended on a desk or in a coffee shop.
Separate Windows accounts keep files, browser sessions and saved passwords apart, and they give you a record of who did what. Add accounts under Settings > Accounts > Other users. In an office this is basic hygiene and part of what our managed services work standardizes.
Start with a Windows update and a restart, since it is usually a driver. If it persists, open Device Manager, expand Biometric devices, uninstall the reader and restart so Windows reinstalls it, then enroll the fingerprint again. Hardware failure on these readers is real but less common than driver trouble.
The Sign-in options page includes Security key support for USB hardware keys. Most home users do not need one. If you handle sensitive accounts or work under a compliance requirement, it is worth discussing alongside the rest of your cyber security setup.
Changing your PIN does not change your Microsoft account password, and changing your password does not change the PIN. Keep track of both. Your password is still what gets you into your account on a different device or on the web.
Because it only works on that one computer. A stolen password lets someone sign in to your account from anywhere, while a stolen PIN is useless without the physical machine, which is protected by its own security hardware and by a lockout after repeated wrong guesses. Different threat, different defense.
On the sign-in screen select I forgot my PIN and verify your identity through your Microsoft account, then set a new one. A local account without a Microsoft account behind it relies on the security questions set when the account was created. If neither route works, the machine may need a rebuild, so keep a second method enrolled.
Windows Hello face recognition uses an infrared camera and depth, which is why it needs specific hardware and why an ordinary webcam cannot be used for it. A printed photograph does not satisfy that check. It is a reasonable protection for everyday use on a personal or office machine.
The account password cannot be removed on a Microsoft account, and that is a good thing. It is your route back in when hardware fails and your way into the account on other devices. Treat biometrics as a faster door, never as the only key.
It works well enough to be worth having, and it is not instant. Windows waits a short while after the paired phone goes out of Bluetooth range before locking, so someone sitting at your desk immediately would still get in. Use it as a backstop behind the habit of pressing Windows key and L.
