• At least 9 characters.
• Contains uppercase and lowercase letters.
• Contains numbers.

<script src="pswmeter.min.js"></script>

Create a container to place the password strength meter.

<div id="pswmeter"></div>

Create a container to place the feedback message.

const myPassMeter = passwordStrengthMeter({
      containerElement: '#pswmeter',
      passwordInput: '#psw-input'
 });

const myPassMeter = passwordStrengthMeter({
      containerElement: '#pswmeter',
      passwordInput: '#psw-input',
      showMessage: true, // default: false
      messageContainer: '#pswmeter-message',
      messagesList: [
        'Write your password...',
        'Easy peasy!',
        'That is a simple one',
        'That is better',
        'Yeah! that password rocks ;)'
      ]
 });

Customize the appearance of the password strength meter.

const myPassMeter = passwordStrengthMeter({
      containerElement: '#pswmeter',
      passwordInput: '#psw-input',
