How to check the password for security?

    How to give the user the opportunity to check their password for severity and crack resistance?

    Recently, such a question has arisen more and more often, because there are a few options for resolving the issue.


    Password Strength Checker - GPL License
    The script will tell you in detail, and clearly show what the strength of the crack-resistant password is, and why your password is different (if it is not).


    JQuery Password Strength Meter - MIT License
    The simplest password checker for complexity. In most cases, it is enough with the head. For jQuery.


    Password Strength Meters - License Free
    I think you can limit yourself to the fact that such a script uses Google.


    Javascript Password Strength Meter - LGPL and MIT License
    A good example of how to make beautiful interfaces. It looks solid and strong, but the script is simple as two pennies, and therefore, perhaps, it will not suit you.
