You see the Smartcard option on the sign on screen and need to disable it.
To disable a smart card provider in Windows, you can follow these steps:
Edit the registry: Open the registry key
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers\{8FD7E19C-3BF7-489B-A72C-846AB3678C96} and add a DWORD value "Disabled"=dword:00000001.
Should look like this:
Use Group Policy: Open the local Group Policy editor and navigate to Computer Configuration → Administrative Templates → System → Logon. Find the policy "Exclude credential providers" and configure it.
Disable Smart Card Plug and Play service: This removes the option to insert a smart card when logging in.
One or more of the 3 options above should work in most cases.
