Windows 10: Unable to log into laptop with Microsoft account or PIN after BitLocker restore

I’ve encountered a very strange problem that has completely locked me out of my laptop.I left the laptop running idle for a little while and returned to see the screen was black. I figured it was in sleep mode and pressed a few keys. Nothing happened so I tried the power button. Still nothing so I forced a restart by holding the power button for 5 seconds.When the computer turned back on, I was met with BitLocker, something I had never seen before. Following the instructions I got my BitLocker recovery key by logging into my Microsoft account. I had to reset my password using the attached emai

Hi Irene,

Thank you for posting the query on Microsoft Community. I am glad to assist you on this.

• How are you trying to change the password?

I would suggest you to switch to child account and then try to set a 4 digit PIN from here and check if it works.

PIN sign in for Microsoft Account

I am using the Microsoft account page under family members. In this section where it shows my Grand Daughters Account details there is no option to have a Pin Code, However on my page, as Administrator, I can create a Pin.

 

Unable to log in with a PIN

Hi Scott,

Using a PIN is easier to memorize than a long password. However, issues like this can emerge due to corrupted user profile or there are missing files on your user account folder. If the PIN and password will not work, deleting files in the
Ngc folder can help. To do that, you can follow these steps:

Step #1: Delete the Ngc folder.

• Use your password to log in to Windows 10.
• Open File Explorer and paste this in the URL box:
  
  C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft.
• Right click Ngc folder and choose Properties.
• Navigate to Security tab and click on Advanced button.
• Locate the Owner section at the top and click Change link.
• Enter the object name to select enter Administrators, if you’re using administrator account, or your user name and click
  Check Names and click OK.
• Check Replace owner on subcontainers and objects and click Apply and OK. Now you should be able to access the
  Ngc folder.
• Open Ngc folder, select all files and folders in it and delete them.

Step #2: Start creating a new PIN.

After you’ve deleted everything from Ngc folder, you can create new PIN for your Windows 10 device by doing these steps:

• Go to Settings app, then Account Settings.
• Choose Sign-in Options and click Add a
  PIN.
• Follow the instruction to add a new PIN.
• Test your PIN using the Command Prompt (Admin).
• If you cannot find the Command Prompt Admin, you can enable it using Command Prompt and typing net user
  administrator /active:yes
• After enabling built-in administrator account, you may logon and try resetting the password of the account which is not working. You may disable it later once you are done by entering net user
  administrator /active:no in
  Command Prompt. You can use this also if you want to change passwords or
  PINs in other User Accounts.
