How to use it:

1. Load the password-strength.js jQuery plugin's files in the document.

<link rel="stylesheet" href="/path/to/asset/password-strength.css" />
<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/asset/password-strength.js"></script>

2. Attach the plugin to the password field and validate the password strength on keyup.

<input type="password" class="form-control" name="password" id="password" placeholder="Password">
$('#password').keyup(function(event) {
  var password = $('#password').val();

3. Create a container in which you will see a progress bar indicating the password strength: weak, medium, average, or strong.

<div id="password-strength-status"></div>

4. Create a list of password criteria that automatically updates to indicate whether the password strings meet the password requirements.

<ul class="pswd_info" id="passwordCriterion">
  <li data-criterion="length" class="invalid">8-15 <strong>Characters</strong></li>
  <li data-criterion="capital" class="invalid">At least <strong>one capital letter</strong></li>
  <li data-criterion="small" class="invalid">At least <strong>one small letter</strong></li>
  <li data-criterion="number" class="invalid">At least <strong>one number</strong></li>
  <li data-criterion="special" class="invalid">At least <strong>one Specail Characters </strong></li>
