A password strength meter for jQuery. [Give it a try!][web]



![password example][example]



Installation

------------



Using npm



~~~bash

npm install --save password-strength-meter

~~~



Using bower



~~~bash

bower install --save password-strength-meter

~~~



Or much better, using yarn



~~~bash

yarn add password-strength-meter

~~~



For manual installations check out the [releases][releases] section for tarballs.



Usage

-----



Import the required scripts:



~~~html



~~~



Ensure your password field has a wrapper div, like in Bootstrap:



~~~html



  

    Password

  

  



~~~



And call the plugin when you wanna enable it:



~~~javascript

$('#password').password({ /* options */ });

~~~



### Available options



Here's the list of available options you can pass to the `password` plugin:



~~~javascript

$('#password').password({

  enterPass: 'Type your password',

  shortPass: 'The password is too short',

  containsField: 'The password contains your username',

  steps: {

    // Easily change the steps' expected score here

    13: 'Really insecure password',

    33: 'Weak; try combining letters & numbers',

    67: 'Medium; try using special characters',

    94: 'Strong password',

  },

  showPercent: false,

  showText: true, // shows the text tips

  animate: true, // whether or not to animate the progress bar on input blur/focus

  animateSpeed: 'fast', // the above animation speed

  field: false, // select the match field (selector or jQuery instance) for better password checks

  fieldPartialMatch: true, // whether to check for partials in field

  minimumLength: 4, // minimum password length (below this threshold, the score is 0)

  useColorBarImage: true, // use the (old) colorbar image

  customColorBarRGB: {

    red: [0, 240],

    green: [0, 240],

    blue: 10,

  } // set custom rgb color ranges for colorbar.

});

~~~



*NOTE*: The custom color bar values use rgb color codes within a reasonable range. The blue must be a single value as we

need a base value on which to calculate the color changes.



### Events



There are two events fired by the `password` plugin:



~~~javascript

$('#password').on('password.score', (e, score) => {

  console.log('Called every time a new score is calculated (this means on every keyup)')

  console.log('Current score is %d', score)

})



$('#password').on('password.text', (e, text, score) => {

  console.log('Called every time the text is changed (less updated than password.score)')

  console.log('Current message is %s with a score of %d', text, score)

})

~~~



Compatiblity

------------



This plugin was originally created in 2010 for jQuery 1.14, and the current release

has been tested under jQuery 1, 2 & 3.



It should work in all browsers (even IE 666).



Testing

-------



First you'll need to grab the code, as the npm version does not come with the

source files:



~~~bash

git clone https://github.com/elboletaire/password-strength-meter.git

cd password-strength-meter

npm install

npm test

~~~



> Note: tests are just run using jQuery 3.



Why?

----



Why another library? Well, I found this on March 11th (of 2017) cleaning up my

documents folder and noticed I made it in 2010 and never published it, so I

decided to refactor it "a bit" (simply remade it from the ground-up) and publish

it, so others can use it.
