The “password-generator.js” is a well-developed JavaScript plugin that helps you to create a random password generator tool for your signup/registration forms. It allows users to generate a strong password including special characters, numbers, and letters.

The plugin comes with a range slider and toggle button controls to enable/disable uppercase letters, lowercase letters, numbers, and symbols for passwords. Users can control the length of passwords through a range slider. Moreover, the generated password can be copied to the clipboard by clicking the copy button.

You can integrate this random password generator tool into your signup form to allow users to generate a strong password for their accounts.

How to Create JavaScript Random Password Generator

1. This password generator tool uses Font Awesome for the copy icon for the generated password copy to the clipboard button. So, load the Font Awesome 5 CSS into the head tag of your HTML page.

<!-- Font Awesome 5 -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.11.2/css/all.min.css">

2. Create the HTML structure for the password generator tool as follows:

<div class="container">
    <h2 class="title">Password Generator</h2>
    <div class="result">
        <div class="result__title field-title">Generated Password</div>
        <div class="result__info right">click to copy</div>
        <div class="result__info left">copied</div>
        <div class="result__viewbox" id="result">CLICK GENERATE</div>
        <button id="copy-btn" style="--x: 0; --y: 0"><i class="far fa-copy"></i></button>
    </div>
    <div class="length range__slider" data-min="4" data-max="32">
        <div class="length__title field-title" data-length='0'>length:</div>
        <input id="slider" type="range" min="4" max="32" value="16" />
    </div>

    <div class="settings">
        <span class="settings__title field-title">settings</span>
        <div class="setting">
            <input type="checkbox" id="uppercase" checked />
            <label for="uppercase">Include Uppercase</label>
        </div>
        <div class="setting">
            <input type="checkbox" id="lowercase" checked />
            <label for="lowercase">Include Lowercase</label>
        </div>
        <div class="setting">
            <input type="checkbox" id="number" checked />
            <label for="number">Include Numbers</label>
        </div>
        <div class="setting">
            <input type="checkbox" id="symbol" />
            <label for="symbol">Include Symbols</label>
        </div>
    </div>

    <button class="btn generate" id="generate">Generate Password</button>
</div>

3. Style the password generator tool using the following CSS. You can customize the layout and design according to your needs.
