Generate Strong Random Password In Javascript

A strong password is important because it provides the first line of defense against unauthorized access to your online accounts, personal information, and sensitive data.

A weak password can easily be guessed or cracked by hackers, leaving you vulnerable to cyber attacks, identity theft, and data breaches.

A strong password should be complex, unique, and not easily guessable. It should include a combination of upper and lowercase letters, numbers, and special characters, and should be at least 10 to 12 characters long. By using a strong password, you can help protect yourself and your information from potential security threats.

In this blog post I am going to share a simple javascript code to generate Generate Strong Random Password In Javascript.

function generatePassword() {
  const lowerCaseLetters = "abcdefghijklmnopqrstuvwxyz";
  const upperCaseLetters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
  const numbers = "0123456789";
  const specialCharacters = "[email protected]#$%^&*()_+-=[]{}|;':,.<>/?";

  const allChars = lowerCaseLetters + upperCaseLetters + numbers + specialCharacters;
  let password = "";

  for (let i = 0; i < 16; i++) {
    let randomIndex = Math.floor(Math.random() * allChars.length);
    password += allChars[randomIndex];

  return password;


This code generates a strong random password that consists of 16 characters and includes lowercase letters, uppercase letters, numbers, and special characters. The password is stored in the password variable and returned when the function is called.
