Windows - Unable to logon with PIN (hexadecimal error code)
When a user uses their PIN to logon to a Windows computer, they may get an error similar to this:

Use the following steps to remediate the error.
This requires clearing all TPM keys, inputting the BitLocker recovery key for the machine, signing in with administrative credentials (AzureAD only) after a reboot to log back into Intune, and re-setting the management name and primary user for the machine.
- Restart the computer, go into BIOS settings. This will vary by PC model.
- Locate the Clear TPM option to clear all TPM keys on next reboot.
- For Dell systems, this is under Security > TPM. You may have to enable Advanced Setup mode on the top left of the screen if this is a newer BIOS to be able to view the Clear TPM option.
- Have the computer reboot.
- Once a BitLocker recovery screen appears, use Intune to obtain the recovery key for the machine that matches the key/drive ID.
- Once the key is entered and correct, Windows will proceed to start.
- Sign in with your admin credentials (with the Password option) under rellis.tamus.edu domain.
-
You should encounter this dialog box once you sign in. Click sign in, and enter your password and MFA.
- Once you do so, after a couple of minutes a screen like "Almost there - create your PIN" should appear. Click OK, and log off of the computer and log back in with your password again.
- Upon logging in, you should see the Account setup wizard to verify MFA and create a new PIN.
- Once you are back at the desktop, search for "Access work or school" and verify that configuration policies are synced to the machine.
- Go to the Intune admin center and look up the machine name, and re-enter the correct management name and primary user (if applicable) for the machine.
- Have the user sign in with their username and password.
- Due to TPM being cleared, all PINs on the system are cleared. It should show up with the Windows OOBE prompting them that a PIN is required and they need to set one up, similar to first-logon tasks.
