Login with Fingerprint no longer working after latest 25H2 update.

Question

Login with Fingerprint no longer working after latest 25H2 update.

Joe S 40

Login with Fingerprint is no longer working after the latest Windows 11, 25H2 update. It recognizes my fingerprint but immediately says "your pin is required to sign in".

I have removed my fingerprint and PIN, restarted the computer, re-added the PIN and fingerprint, but continue to experience the same issue.

The issue started after the most recent round of updates. KB5066835, KB5066128, and KB5068331 were installed today.

Anyone else experiencing this issue?

MY fingerprint won't work, either. but MY update history doesn't show ANY of those numbers. it doesn't have anything that says 25H2, either, but my settings say I am up to date. I have not been on my computer from early Aug til Dec 6.

I also had this issue after an update. I use an external finger print reader and needed this enabled:

Hi,

To start, please open Device Manager → Biometric Devices, right-click your fingerprint sensor, and select Uninstall device (check “Delete the driver software for this device” if available). Then restart your system and let Windows automatically reinstall the driver. If Windows doesn’t reinstall it automatically, visit your device manufacturer’s support site (for example, Dell, HP, Lenovo) and manually install the latest fingerprint driver certified for Windows 11, version 25H2.

Next, try running the Windows Hello troubleshooter:

Go to Settings → System → Troubleshoot → Other troubleshooters → Windows Hello sign-in,
Then follow the on-screen recommendations.

You can also clear stored biometric data by opening an elevated Command Prompt and running:


certutil -deleteHelloContainer

After that, re-register your fingerprint and test sign-in again.

I hope these steps help restore your fingerprint login functionality! If this solution resolves your issue or helps point you in the right direction, please click “Accept Answer” so others in the community can benefit from it as well 😊

Best regards,

I will test but it seems unlikely it would resolve the issue. The fingerprint sensor is detected by Windows. It was working with Windows 11 25H2 until KB KB5066835 was installed. Even with KB5066835, it recognizes my fingerprint but immediatley prompts for the PIN. I also proved the fingerprint sensor is working because I was able to remove the PIN and fingerprint and re-add them. While waiting for a response I removed KB5066835 and the functionality returned to normal.

KB5066835 reinstalled. Issue returned.

I ran the certutil -deleteHelloContainer command. I logged out, logged back in, set up PIN and fingerprint again. No change. The fingerprint is still recognized but it immediately prompts for the PIN.

There is no Windows Hello Sign-In troubleshooter at Settings → System → Troubleshoot → Other troubleshooters → Windows Hello sign-in,

I have exactly the same issue, can reproduce it on 2 machines. I have an IR camera so can use that. But the fingerprint fails on both exactly as described.

Restoring a backup image pre 25H2 the functionality works.

Same issue. Fingerprint not recognized, can't enter PIN. I am currently using System Restore to restore the system to before yesterday's update. If this works, I will refuse the update until the issue is resolved. I will monitor this thread for a solution.

Same issue here and uninstalling KB5066835 fixed it.

Yesterday, I was unable to login with my fingerprint or PIN. I had to login to my microsoft account and resetup my PIN. My PIN was lost. Then next time I logged in, my fingerprint didn't work and I had to use my PIN again. In settings, I no longer had a fingerprint saved. So, I had to set up my fingerprint again. Now it appears to work again. I don't know why my fingerprint and PIN were lost.

Now periodically, and I don't know why, my fingerprint won't work for logging in and I have to use my pin. Next time I log in, the fingerprint works again.

After updating to 25H2, Windows Hello is still malfunctioning. The above solution does not solve the issue. Now the troubleshooter is stuck on the taskbar and completely rendering the start menu unusable and unresponsive to any input. I had to restart the computer manually as it was not able to interact with the start button at all! The problem is that you broke the system without testing the new updates every single time since 2019. Instead of proper testing, you push updates out and create more problems than you solve. When are you going to stop this and fix everything before you finally move on?

I used the method CMD > "certutil -deleteHelloContainer". After that it works, I am able to register the fingerprint. Thank You

UPDATE: I had previously reinstalled Windows 25H2 with the latest updates but continued to see the issue. Every time I would scan my fingerprint, I would be prompted for my PIN. Last week, the November updates installed and the fingerprint login is now working as it should.

My issue has not been resolved. Uninstalling KB5066835 temporarily fixed the issue until it reinstalled.

I am having the same issue. I have followed the instructions above and Windows Hello keeps telling me I have to use my pin, even though it recognizes my pin.

I reinstalled Windows 11 25H2 and installed all currently available updates. I continue to see the same problem.
