Build a Password Generator Website

Introduction

Hello, developers! I'm excited to present my latest project: a Password Generator. This tool is designed to help you create secure and random passwords with ease. Whether you need strong passwords for your online accounts or want to practice your JavaScript skills, this Password Generator is a great addition to your toolkit.

Project Overview

The Password Generator is a web-based application that allows users to generate passwords with various configurations. You can customize the password length and include or exclude specific character types like lowercase letters, uppercase letters, numbers, and symbols. This project showcases how to build a dynamic password generator using JavaScript, coupled with a clean and user-friendly interface built with HTML and CSS.

Features

  • Customizable Password Length: Adjust the length of the generated password using a slider.
  • Character Type Selection: Choose which types of characters (lowercase, uppercase, numbers, symbols) to include in the password.
  • Generate and Copy: Generate a random password and easily copy it to your clipboard.

Technologies Used

  • HTML: Provides the structure and layout for the Password Generator.
  • CSS: Styles the interface, ensuring a modern and responsive design.
  • JavaScript: Handles the password generation logic, including user interactions and password copying.

Project Structure

Here's an overview of the project structure:

Code Explanation

HTML

The index.html file defines the structure of the Password Generator, including the input fields, controls, and the display area. Here’s a snippet:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="stylesheet" href="style.css" />
    <link
      href="https://fonts.googleapis.com/icon?family=Material+Icons"
      rel="stylesheet"
    />
    <script src="script.js" defer></script>
    <title>Password Generator</title>
  </head>
  <body>
    <div class="container">
      <h1>Password Generator</h1>

      <div class="inputBox">
        <input type="text" class="passBox" id="passBox" disabled />
        <span class="material-icons" id="copyIcon">content_copy</span>
      </div>

      <input type="range" min="1" max="30" value="8" id="inputSlider" />

      <div class="row">
        <p>Password Length</p>
        <span id="sliderValue"></span>
      </div>

      <div class="row">
        <label for="lowercase">Include Lowercase Letters (a-z)</label>
        <input type="checkbox" name="lowercase" id="lowercase" checked/>
      </div>

      <div class="row">
        <label for="uppercase">Include Uppercase Letters (A-Z)</label>
        <input type="checkbox" name="uppercase" id="uppercase" checked/>
      </div>

      <div class="row">
        <label for="numbers">Include Numbers (0-9)</label>
        <input type="checkbox" name="numbers" id="numbers" checked/>
      </div>

      <div class="row">
        <label for="symbols">Include Symbols (@-*)</label>
        <input type="checkbox" name="symbols" id="symbols" checked/>
      </div>

      <button type="button" class="genBtn" id="genBtn">

CSS

The style.css file styles the Password Generator, making it visually appealing and responsive. Below are some key styles:

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-family: sans-serif;
}

JavaScript

The script.js file contains the logic for generating passwords, managing user interactions, and copying passwords to the clipboard. Here's a snippet:

let inputSlider = document.getElementById("inputSlider");
let sliderValue = document.getElementById("sliderValue");
let passBox = document.getElementById("passBox");
let lowercase = document.getElementById("lowercase");
let uppercase = document.getElementById("uppercase");
let numbers = document.getElementById("numbers");
let symbols = document.getElementById("symbols");
let genBtn = document.getElementById("genBtn");
let copyIcon = document.getElementById("copyIcon");

// Showing input slider value 
sliderValue.textContent = inputSlider.value;
inputSlider.addEventListener("input", () => {
  sliderValue.textContent = inputSlider.value;
});

genBtn.addEventListener("click", () => {
  passBox.value = generatePassword();
});

let lowerChars = "abcdefghijklmnopqrstuvwxyz";
let upperChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
let allNumbers = "0123456789";
let allSymbols = "~!@#$%^&*";

// Function to generate Password
function generatePassword() {
  let genPassword = "";
  let allChars = "";

  allChars += lowercase.checked ? lowerChars : "";
  allChars += uppercase.checked ? upperChars : "";
  allChars += numbers.checked ? allNumbers : "";
  allChars += symbols.checked ? allSymbols : "";

  if (allChars === "") {
    return genPassword;
  }

  let i = 1;
  while (i <= inputSlider.value) {
    genPassword += allChars.charAt(Math.floor(Math.random() * allChars.length));
    i++;
  }

  return genPassword;
}

copyIcon.addEventListener("click", () => {
  if (passBox.value !== "") {
    navigator.clipboard.writeText(passBox.value);
    copyIcon.innerText = "check";
    copyIcon.title = "Password Copied";

    setTimeout(() => {
      copyIcon.innerHTML = "content_copy";
      copy

Icon.title = "";
    }, 3000);
  }
});

Sooooo, it is password validator??? Correct me if I'm wrong, generator it is something that was started and then works on its own. Like I pressed a button and got a random password.
