Remember last we talked about Ajax Password Strength Meter by Code and Coffee which is not very useful because of the bad algorithm. Today we have a JQuery Password Strength Meter which is a small plug in that provides an easy way to show the strength of a users password as well. The algorithm seems to be a lot better than the last one and the Author said he is still improving the algorithm. JQuery Password Strength Meter provides some simple options that allow you to customize the output. You can define the strength of the meter easily by adjusting the score for each requirement.

Requirements: JQuery Framework
