We will use a little bit of jQuery and the build in progress bar from bootstrap to achieve the stylish password indicator.

JavaScript Function

/* Password strength indicator */
function passwordStrength(password) {

	var desc = [{'width':'0px'}, {'width':'20%'}, {'width':'40%'}, {'width':'60%'}, {'width':'80%'}, {'width':'100%'}];
	var descClass = ['', 'progress-bar-danger', 'progress-bar-danger', 'progress-bar-warning', 'progress-bar-success', 'progress-bar-success'];

	var score = 0;

	//if password bigger than 6 give 1 point
	if (password.length > 6) score++;

	//if password has both lower and uppercase characters give 1 point	
	if ((password.match(/[a-z]/)) && (password.match(/[A-Z]/))) score++;

	//if password has at least one number give 1 point
	if (password.match(/d+/)) score++;

	//if password has at least one special caracther give 1 point
	if ( password.match(/.[!,@,#,$,%,^,&,*,?,_,~,-,(,)]/) )	score++;

	//if password bigger than 12 give another 1 point
	if (password.length > 10) score++;
	// display indicator
