PIN sign-in option is very convenient to login into Windows 8 or later. In this article, learn how to fix, if PIN not working in Windows 10 on your system.

A 4-digit PIN is supposed to be most easiest way to sign-in to Windows 10. Since it is easy to remember and convenient to use, we recommended you to use PIN as the primary sign-in option on your Windows.

FIX PIN Not Working In Windows 10

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 : PIN Not Working In Windows 10

FIX 1 – By Altering Permissions

1. Press W8K + E to open File Explorer and click View > Show/hide and check Hidden items. Assuming Windows is installed on C: drive, navigate to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft folder. Then right click on Ngc folder and select Properties.

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.

Hope this helps!

  • 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?

    Thanks.

  • 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.
    Luke

  • 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: https://www.kapilarya.com/how-to-repair-windows-10-using-in-place-upgrade

  • 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.

  • Hi Kapil,
    I appreciate this is an older post, but I am having this problem now and cannot complete your fix. When I get to the Microsoft folder, the NGC folder has a shortcut symbol on it, despite it not identifying as a shortcut. When clicking on properties, it has nothing in it, and when I try to open it I get an error message saying “The name of the file cannot be resolved by the system”.
    Is the NGC folder corrupt in some way?

  • Kapil Arya

    ^^ I believe the folder is corrupted and you can delete the shortcut as well. Then try FIX 2. This worked for Richard in above comment, so see if it works for you. If you doubt, make sure to create System Restore point first.

  • I am asked for password but I haven’t used that in so long. I have always used PIN. login screen won’t give me option for PIN. how do I get PIN login access again

  • Kapil Arya

    ^^ If you’re on Microsoft account, reset the password online and log in with new password on the machine. Once you logged in, try the above mentioned fix and see if PIN works now.

  • I have tried this (Fix 1) on new laptop (Dell Vostro, Win 10 Pro) that has had the problem intermittently from day 1 and so far it seems to be working – this after 24 hours with lots of waking from sleep – with locked screen – and a couple of reboots. It is the only fix that has worked – removing/changing pins and passwords didnt make any lasting difference – so I am keeping my fingers crossed.
    Many thanks for posting it.

    ^^ Glad it helped, nick 😎

  • Lasted 3 days, now back to getting 0x8009002d error regularly on waking from sleep :-(

  • Two weeks in and this fix is working – except for the first (and only the first) wake from sleep after a windows update, then I get the 0x8009002d error code. But do a restart and all is well again :-)

  • Hi,

    All was going fine until the file structure just stops at C:\Windows\ServiceProfiles\LocalService

    There are no AppData etc subfolders. Suggestions?

    Latest Win 10, all updated. Dell Inspiron 27 that Dell had the m/board replaced today as B/tooth and camera had just quit. Since then I am having the issues with PIN setup.. Thank you.

  • Dominic
    Its a hidden folder, make sure ‘view hidden folders’ is selected in folder options.

    I have a shortcut folder where ngc is.
    Cant change the access to this folder in this way

  • HI kapil, i tried with both steps still issue not resolved:-(

    May i know what i do now

  • Hi Kapil, I tried fix2 but the following is displayed:

    C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc: Access is denied.
    C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc\*: Access is denied.
    Successfully processed 0 files; Failed processing 2 files

    What should i do now?

  • Kapil Arya

    ^^ Make sure you’re signed in as administrator. If it still doesn’t works, go to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc and take ownership of Ngc folder.

  • tried both fixes,without success.
    My situation: After a hard drive crash and subsequent replacement of hard drive by mfgr,I recovered everything from a mirror image (created regularly by my Carbonite software). Everything now works, with these exceptions: PIN login does not work, and I cannot login to my Microsoft account.

  • Kapil Arya

    ^^ Switch to local account, remove PIN. Add PIN and switch back to Microsoft account, see if that works that way!

  • That’s so complicated. Why so much trouble, if it’s not one thing with computers it’s another. I’m fed up.

  • Thank you very much! It works!

  • Kapil Arya

    ^^ You’re most welcome 😊

  • I still cannot set fingerprint but Fix 1 has worked and resolved the PIN issue. I really hope it lasts. Thanks a lot.

  • Kapil Arya

    ^^ Glad I could help 😎

  • Thanks so much. Been struggling with by mucking around with credentials and trying to reset my pin among other things for the past few months. Fix 1 worked without a hitch.

  • Kapil Arya

    ^^ That’s awesome, AI 😊

  • Phew~ I could fix this PIN code login fail problem by deleting all files and folders in the Ngc folder one by one in the Command Prompt of the restart advanced options after taking the ownership and resetting the access permission entry. The hash-named folder in the Ngc folder couldn’t be deleted while it still has some files and folders, so I CDed into the subfolders one by one and deleted all files in them and did the same thing if they have subfolders. Fortunately, there were not so many subfolders and files, I could finish it in a not long time with the combination of the del and rmdir commands.

  • Resetting ACL’s worked perfectly, i was struggling to find a solution, thank you very much

  • Kapil Arya

    ^^ Glad to help 😎

  • Amazing! this did the trick. Thanks a lot!!!!

  • Kapil Arya

    ^^ Happy to help, Guillermo 😊

  • When I use fix 2, I get ‘icals’ is not recognized as an internal or external command, operable program or batch file. PLEASE HELP, I have been stuck with this not working pin for a week now

  • I struggled resetting the alcs on the ngc folder. when i tried to run it in the admin command promt it told me that “access is denied” and that it “failed processing 2 files”

  • I don’t have a ngc folder or the same structure folders as you detail above

  • Kapil Arya

    ^^ Recheck the location, it must be there. Note that AppData is hidden folder.

  • How did you get past the error screen – the Win key + E doesnt do anything

  • I had the same issue, it works but after one or two reboots the problem just reappears and the permissions on the folder even change back. I fixed it by just making a new user and moving my data and microsoft account to the new user account. No more pin problems after that.

  • Kapil Arya

    ^^ Thanks for sharing this!

  • I got an 1803 update and now I can remove the OLD PIN and change and it is working. Infact post the update the log in screen prompted me to change the PIN. It is working now. So something in 1709 broke it.

  • Kapil Arya

    ^^ Glad V1803 Update sorted this for you!

  • In my surface laptop it’s not allowing me to get in it saying your pin is no longer available due to security settings on the device. I see only this screen it’s not showing me anything to put in login credentials. After I restarted many times still it is not to do anything in the system.

  • Kapil Arya

    ^^ This is widely reported issue with latest update. Can you see the password icon under Sign-in options?

  • Hi Kapil,

    I could solve this in my DELL XPS 13 running W10. Only thing is that we must press “windows” Key& “E” while rebooting.

    Thanks.

  • Kapil Arya

    ^^ Thank you for sharing this 😊 Hope it helps others!

  • Brand new Surface Pro…can’t seem to fix this issue.

    Instead of trying a dozen different work around why can’t Microsoft just write an update and fix the bloody thing properly??

  • Kapil Arya

    ^^ Try repair upgrade: https://www.kapilarya.com/how-to-repair-windows-10-using-in-place-upgrade

  • I have no option to sign in for PIN. Also after clicking the start button I only get message that due to changes in the safety values, your PIN is on this device nit available. And i did not get any kind of menu or so to make changes. It seems i am lockec out and i cannot get into the surface laptop.

  • Kapil Arya

    ^^ You can use password sign-in and try above mentioned fix then.

  • no don’t have that file on my computer at all anywhere….

  • Does anyone know why this PIN issue is occurring? I am trying to get to a root cause so I can proactively mitigate it.
