Integrate Password Strength Checker into Registration Forms

Password Strength Checker is an application that is designed to assess the strength of password strings. The instantaneous visual feedback provides the user a means to improve the strength of their passwords, with a hard focus on breaking the typical bad habits of faulty password formulation. Since no official weighting system exists, Password Strength Checker has created its own formulas to assess the overall strength of a given password.

Password Strength Check is written in Javascript and released under GPL License. You are allowed to download this application and integrate it into your web application. I am sure it will help users choosing a more secure password when filling in registration forms. However, this application is neither perfect nor foolproof, and should only be utilized as a loose guide in determining methods for improving the password creation process.
