Displayed user-names
By default, Mac OS X displays a list of user-names with accompanying graphic at the console login prompt.

Disable this setting from: System Preferences -> Accounts -> Login Options -> Display Login Window as: Name and password
Password hints
Password hints allow users to set a hint if they have forgotten their passwords. While this is a helpful feature for some home users who don’t login very often, it is typically not appropriate in a corporate environment, as it increases the risk of an attacker successfully guessing the password. To disable password hints on the system, open the file /Library/Preferences/com.apple.loginwindow.plist as root, in the Property List Editor application: sudo open /Library/Preference /com.apple.loginwindow.plist Change the RetriesUntilHint value to 0.
