This is a neat app, but in order to operate, you need to remove the passcode from your comuter, thus, when the app closes, the password will still not be set up, so keep in mind that in order to restore your password, go to System Preferences>Privacy/Security>General>Require Password Immediately. Nice photos and a sleek interface, it changes up the lockscreen in a good way, but on the pattern unlock, having to hold the mouse down is a bit annoying.
