Windows Hello Fingerprint Stopped Working? Try These Fixes First

1. You disabled Windows Hello in Sign-in Options

I know this sounds too simple, but I can't tell you how many times I've seen this trip people up. You're trying to log in, the fingerprint sensor won't respond, and it turns out you accidentally turned off Windows Hello entirely. This happens more often than you'd think, especially after a Windows update or if you've been fiddling with other sign-in settings.

Here's the fix:

1. Press Windows Key + I to open Settings.
2. Go to Accounts > Sign-in options.
3. Under Windows Hello Fingerprint, click Remove (if it's already set up, remove it first).
4. Then click Set up and follow the prompts. You'll need your PIN or password to verify.

This clears any corrupt fingerprint data stored on the sensor. If the option to set up is grayed out, skip to the next fix—it's likely a driver issue.

On some Lenovo ThinkPads and Dell XPS models (like the XPS 13 9300), I've seen the sensor get stuck in a low-power state after a driver update. Removing and re-adding the fingerprint profile forces the sensor to reinitialize. Nine times out of ten, this is all you need.

2. The Sensor Driver Got Messed Up

Windows Update is great—until it quietly replaces your perfectly working sensor driver with a generic one. This happens on hardware from Synaptics, Goodix, and ELAN. The result? The sensor shows up in Device Manager with a yellow exclamation mark, or it doesn't show up at all.

Let's fix that:

1. Right-click the Start button and select Device Manager.
2. Expand Biometric devices. You should see something like "Synaptics Fingerprint Sensor" or "ELAN Fingerprint Sensor".
3. Right-click it and select Update driver > Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
4. If you see multiple versions, pick the one dated before the problem started. Avoid "Windows Update" drivers—they're often the culprit.
5. Click Next and restart your PC.

If you don't see any biometric devices at all, your sensor might be disabled in the BIOS. Reboot, mash F2 or Del to enter BIOS setup, look for something like "Security" > "I/O Interface" > "Fingerprint Device", and make sure it's set to Enabled. This is more common on business laptops like the HP EliteBook 840 G8.

For stubborn cases, go directly to your laptop manufacturer's support site and download the latest fingerprint driver. Don't let Windows Update install it—install it manually. On Dell models, the driver is often named "Dell ControlVault2 Driver and Firmware Update". On Lenovo, look for "Fingerprint Sensor Driver for Windows 10/11".

3. The PIN Login Loop Is Blocking Biometrics

Here's a weird one: Windows Hello fingerprints won't work if your PIN is broken or stuck in a login loop. I've seen this on Windows 10 20H2 and Windows 11 22H2. The symptom is you try to log in with your PIN, but Windows keeps asking for it again, or it says "Something went wrong". Meanwhile, the fingerprint sensor acts dead.

The fix is to reset your PIN:

1. Press Windows Key + I to open Settings.
2. Go to Accounts > Sign-in options.
3. Under PIN (Windows Hello), click I forgot my PIN.
4. You'll need to enter your Microsoft account password. Then you can create a new PIN.
5. Once that's done, go back up to the fingerprint section and remove/re-add your fingerprint profile.

I recommend using a PIN that's at least 8 characters long with mixed numbers and letters—longer PINs tend to be more stable across updates. If the PIN reset fails, you might need to sign out completely, sign back in with your Microsoft account password, and try again.

After resetting the PIN, the fingerprint sensor should now respond. Test it by locking your PC (Windows Key + L) and tapping the sensor.

Quick-Reference Summary

These three fixes cover about 90% of the Windows Hello fingerprint failures I've encountered over the years. If none of them work, you might have a hardware issue—test the sensor in another OS (like a Linux live USB) to confirm. But try these first. They've saved me hours of frustration, and I'm betting they'll do the same for you.
