# Quick Start

Adding the Enzoic Password Strength Meter to your existing signup or password change form is simple.

## **1.  Include the Enzoic JS Library**

Add the following script include before your closing body tag:

```html
<script async type="text/javascript" 
            src="https://cdn.enzoic.com/js/enzoic.min.js" />
```

## **2.  Enable Enzoic on Your Password Input Control**

Add the “enz-enable” attribute to your signup form’s password input element:

```html
<input type="password" enz-enable />
```

Alternatively, you can call the applyToInputElement function:

```html
<script type="text/javascript">
    var passwordEl = document.getElementById('id_of_your_password_input');
    Enzoic.applyToInputElement(passwordEl);
</script>
```

Delete any existing password strength meter from the page, as you will no longer need it.

## **3.  Modify Your Form Validation Logic**

Add in code to prevent the user from submitting the form if the password strength is insufficient. The mechanism for alerting the user will be specific to your page, but a basic code snippet in JavaScript for this is below:

```javascript
  // typically this is the onsubmit event handler for your signup form
 function formSubmit() {
 
      // check if the current password meets your desired
      // strength score (strong in this case)
      if (Enzoic.currentPasswordScore <
          Enzoic.PASSWORD_STRENGTH.Strong) {
 
          // password is not strong enough, do something
          // here to indicate to the user that they must
          // improve their password's strength before they
          // can move on
 
      }
}
```

## **That’s it!**

You’re done! When you reload the page, your password input will now have the Enzoic frame around it when it is focused.
