However, there are some cases when you find that PIN is no longer working. These might be the symptoms in such cases:

  • You cannot add, update PIN
  • You added a PIN as sign-in option but it is not being offered at login screen
  • PIN sign-in is offered but when you type your PIN, system doesn’t accepts it
  • PIN sign-in stuck and you need to restart the machine and use another sign-in option such as password
  • You added PIN and it worked perfectly, but after some update, it is broken

If either of above mentioned cases applies to you, this article is for you. You can try the fixes mentioned below and fix it for yourself:

FIX 1 – By Altering Permissions

Once you provided full control to yourself, you should check the status of issue. It should be resolved by now.

FIX 2 – By Resetting ACLs On Ngc Folder

This problem might also occur, if Access Control Lists (ACLs) on Ngc folder are corrupted. Thus you must reset ACLs for Ngc folder to make PIN working again.

Right click on Start Button and select Command Prompt (Admin). In the Command Prompt window, type following command (replace C: with your system root drive) and press Enter.

icacls C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc /T /Q /C /RESET

Close Command Prompt. You might need to add a new PIN now and it should work as expected.

  • Thank you! I tried like 6 different solutions before I found your site. This actually worked! I appreciate it so much.

  • Kapil Arya

    ^^ Glad we could help 😎

  • you are a genius – thanks!

  • Kapil Arya

    ^^ Awesome 😎

  • Really smart solution. Thank you!

  • Kapil Arya

    ^^ You’re most welcome!

  • Thanks, worked great!
    But I am wondering how to reset ownership tp the default state. In the linked post you just say “set back to original owner”…but in this case the original owner cannot be displayed before taking ownership…

    So…how to resest to original state? Or is that not necessary?


  • No luck with my pin problem. Ngc folder is present but after creating the pin no files ever show up inside Ngc

  • Kapil Arya

    ^^ Have you tried resetting ACLs?

  • Hi Kapil,

    The PIN functionality ceased working after the Fall Creators Update. I’ve tried both your fixes above.

    At the sign-in screen, I’m told:

    “Something went wrong (code: 0x80070032). Restart your device to see if that fixes the problem.”

    and the settings menu, after I click Add PIN, I get the pop-up message

    “We couldn’t sign you in. {User name} {User email}. This request is not supported”.

    Any ideas?

  • Beautiful. Really.

  • Hi Kapil,
    I still can’t make it work despite using all the two fixes. The Fix 2 allows me to set up a pin but the pin won’t work as usual. And the thing will roll back to the pre-fix status. Can’t setup fingerprint either.

    Can I delete what’s in the NGC folder and reset with Fix2?
    Many thanks.

  • Kapil Arya

    ^^ IMO, FIX 2 won’t work if you delete NGC folder. Anyway, you can try that but create a System Restore point first and then proceed.

  • This worked for me at first, until I turned off my laptop (NOT sleep, NOT hibernate).

    When I turned on my laptop again, the issue had reappeared.

    So it appears this is only a temporary fix.

  • Kapil Arya

    ^^ In that case, repair upgrade may fix it permanently:

  • I have tried all of the above and still cannot create a pin. Windows 10, 1709, 16299.125.

  • It’s January and I’m just now starting to have trouble where I cannot use the fingerprint login and cannot set a pin. I get the message

    We couldn’t sign you in. The request is not supported.

    I wound up having to take ownership of the Ngc directory, remove it’s contents (a GUID directory), delete the Ngc folder. Create the Ngc folder. Run the command
    icacls C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc /T /Q /C /RESET

    Then I was able to create a PIN again.
