Slim Password Strength Indicator Bar Plugin For jQuery - passwordStrength.js

passwordStrength.js is a tiny and easy jQuery plugin to shows a progress bar below the password filed that auto fills and changes background color depending on the password strength when typing.

Default validation rules:

• Numerals.
• Uppercase characters.
• Lowercase characters.
• 12 characters.
• Special characters

How to use it:

1. The passwordStrength.js library requires jQuery 1.12 or higher. Make sure to load it before passwordStrength.js.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="js/passwordStrength.js"></script>

2. Call the passwordStrength method to the target password field.

$('#password').passwordStrength();

3. The CSS to style the password strength indicator.

.password-box { display: inline-block; }

.password-progress {
  height: 12px;
  margin-top: 10px;
  overflow: hidden;
  background-color: #f5f5f5;
  border-radius: 4px;
  -webkit-box-shadow: inset 0 1px 2px rgba(0,0,0,.1);
  box-shadow: inset 0 1px 2px rgba(0,0,0,.1);
}

.progress-bar {
  float: left;
  height: 100%;
  background-color: #337ab7;
  -webkit-box-shadow: inset 0 -1px 0 rgba(0,0,0,.15);
  box-shadow: inset 0 -1px 0 rgba(0,0,0,.15);
  -webkit-transition: width .6s ease;
  -o-transition: width .6s ease;
  transition: width .6s ease;
}

.bg-red {
  background: #E74C3C;
  border: 1px solid #E74C3C;
}

.bg-orange {
  background: #F39C12;
  border: 1px solid #F39C12;
}

.bg-green {
  background: #1ABB9C;
  border: 1px solid #1ABB9C;
}

4. Apply your own rules to the password strength indicator.

var rules = {
    rulesname: {
      rule: /[A-Z]+/,
      method: true
    }
}

$.tester.addRules(rules);

5. Public methods.

var tester = $('#password').passwordStrength();

// destroy the plugin
tester.destroy();

// reset the indicator
tester.reset();
