It is 'effortless' and it has made the "/wp-admin" page 'forbidden'. However, the new login page location is hardcoded as "/login". Not surprisingly, within an hour of installing, I'm seeing brute-force attackers now attempting this "/login" page (ie. an obvious page location for hackers). PLEASE, provide a configurable login page name. As is, this plugin is, in reality, useless (ie. hackers guess "login" as an alternate page).
Also, no screens have appeared in my admin section (contrary to those described under "Screenshots").
Also, some spurious error msgs appeared overwriting my screen when I logged in.
=> Uninstalling since no real benefit in current form. Please work on this - WordPress desperately needs a hidden (admin) login page.
