Hello,
If disabling the PIN option through GPO does not work, try disabling PIN logon using the registry. The steps are as follows:
1.Press the Windows key + R to open the Run box. Type regedit and hit Enter.
2.When the Registry Editor opens, navigate to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\default\Settings\AllowSignInOptions
3.In the right pane, you can see a value DWORD entry named “value“. Double-click on it and set it to 0. (If you want to enable PIN logon later on, just change the value back to 1.)
4.Now open the Settings charms to access the User Account Settings, you’ll find the Add PIN option is disabled.
Best Regards,
Yanhong Liu
