Failed Logins - Excellent addition to any web site

Having a display of any recent failed logins, time, date and computer address is a GREAT addition to any web site. The benefit of this is that a given user will know if they did not attempt a login at that date/time. Technical users can help non-technical users determine if the IP logged in from does not belong to the owner of the account. I wish every web application in the world had this function. I am adding it to all of mine. Of course this function needs to be secure ...so it cannot be accessed or modified by hackers through some sort of injection as well.
