Logging in to WordPress from a public computer is not the safest thing to do. The more security layers you add to WordPress, the better off you will be. Login Dongle is an exciting plugin that lets you create a bookmarklet that lets you log onto WordPress by answering a security question of your choice.
Login Dongle is pretty easy to use. Just choose challenge and response for your login dongle and you are set. Drag your login bookmarklet to your browser to start using this script. With this tool, you not only need to have your username and password but also the answer to the challenge question you have picked.
Login Dongle does not change your login name. Your attackers won’t know you have changed it with this script. But they will need the answer to your challenge to log in. Pretty awesome script to improve your login page with.
