How to enable the login of a domain user using PIN on Windows 8
By default, domain users are unable to use a PIN for login, but this can be changed by changing the state of one of the local group policy settings.
So, press Win + R to open the Run window. Type gpedit.msc and press Enter.
When you open «local group policy Editor», navigate to the folder:
Computer configuration Administrative templates System Logon
In the right part of the window, find the option «Enable login with PIN», and double-click it.
Now switch the state from «Not configured» to «Enabled» and then click «Apply».
Next, you must update the current settings group policy. To do this, open the Run window and type the following command gpupdate /force and then press Enter.
Of course, this will only be useful in a domain environment. In this case you can assign this group policy setting to the OU in Active Directory. That’s about it.
