Combine jQuery and zxcvbn to create a password strength meter.


How to use

As of 0.5.0, the wrapper will be automatically added beneath the target input field

Add jquery (tested with 1.10.0), jquery.strengthify.js and strengthify.css to your document.

If using the message option, include bootstrap.

If using the titles option, include bootstrap's tooltip.js,

<script src="jquery-1.10.0.min.js"></script>
<script src="tooltip.js"></script>
<script src="jquery.strengthify.js"></script>
<link rel="stylesheet" href="bootstrap.min.css" type="text/css">
<link rel="stylesheet" href="strengthify.css" type="text/css">

Because zxcvbn is really heavyweight, it will be loaded asynchronously from zxcvbn/zxcvbn.js. This can however be configured with an optional parameter.

Then call .strengthify on the password input field.


That's it. Now the password strength meter will be updated after each keystroke.


The path and the title of the different strength categories can be configured with the first parameter of .strengthify.
