lock screen as root does nto require password to unlock?

When I am logged in as root instead of logging out I want to lock the screen.
As root I do not require a password to unlock the screen.
When I do this as another user I need to re-enter my password to unlock the screen.

How can I make it so as root I need to re-enter the root password when I try to unlock the screen?

Thanks.
