So in your user management portal, you assign new users or replace your lost passwords with passwords you set, thus you know? Oh my days! Generate it randomly and mail the user, or better, mail them a link to reset/create password page. Otherwise, just make it a plain input field, because if you know it, it's not hidden anyways.
