Create random password generator using javascript

Random password generator is used to generate 'n' digit random password using javascript.

You can create a random password generator in JavaScript using various methods. Below is a simple example of how to generate a random password that contains uppercase letters, lowercase letters, numbers, and special characters.

To generate random password in javascript first of all you have to create one javascript file in your favorite code editor and than add following code into that file.

function generateRandomPassword(length) {
  const charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()_-+=<>?";

  let password = "";
  for (let i = 0; i < length; i++) {
    const randomIndex = Math.floor(Math.random() * charset.length);
    password += charset[randomIndex];
  }

  return password;
}

//Example: Generate a random password with a length of 12 characters
const randomPassword = generateRandomPassword(12);
console.log(randomPassword); //output : _tVEF^RVH)8?

Explaination of above code :

• The generateRandomPassword function takes a length parameter that specifies the desired length of the password.

• The charset variable contains all the characters from which the password will be generated. You can customize this to include or exclude specific characters according to your needs.

• Inside the loop, random characters are selected from the charset and added to the password string until it reaches the desired length.

• The function returns the generated random password.
