This class can authenticate users with graphical images.

It generates HTML with JavaScript to display a series of images that correspond code letters relative to a reference image that form the user password.

As the user clicks on the images, a hidden form input is updated with the images codes.

Text based passwords are often easy to crack because users choose obvious words for the passwords.

This class lets users choose passwords and authenticate with graphical images that are mapped to password characters. The users click on the images to enter the passwords.

This way the associated text passwords are not made of words that would be easy to crack.
