In this article we will discuss on how to create a random password generator in JavaScript.

In JavaScript, generating random passwords is easy using these open source projects that I provide all the things you need to learn are there all you need to do is download the entire source code below.

In addition, a random password generator in JavaScript is a web-based application that creates random or customized passwords so that the users can have a stronger password which provides a great and hard security of their account.

This project is designed and created especially for IT students who wish to learn this powerful scripting language called (JavaScript).

What is a random password generator?

A password generator is a tool that automatically generates a password based on guidelines that you set to create strong and unpredictable passwords for each of your accounts.

Furthermore, random passwords can also be generated (manually) using only simple resources such as coins or even dice, but when the technology comes all the manual things are changed into a system implementation.

I will provide sample programs as well as a code explanation so that you can apply these password generators in your entire project.

Generate Random Password In JavaScript With Source Code

First example program:

In JavaScript, there are many methods to make random passwords such as Math.random() and Math.floor() for random numbers and special characters especially if you want to generate number symbols between 0 and x-1 (where x is the string generatepassword length).

They have also a special method to create a random password named .charAt() to get the character of a particular index of a string and return the password.

This will provide a copy of the password and concatenate random characters from the (string) until the random var password of the desired length is obtained and done.

		/* Function to generate combination of password  and id password*/

		function generateP() {

			var pass = '';

			var str = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' +

					'abcdefghijklmnopqrstuvwxyz0123456789@#$';

			for (let i = 1; i <= 8; i++) {

				var char = Math.floor(Math.random()

							* str.length + 1);		

				pass += str.charAt(char)

			}	

			return pass;

		}

		function sch_Run() {

			el_down.innerHTML = generateP();

		}

	</script>

</body>

Second example program:

The second sample program we use a method called Math.random() design to generate numbers within 0 and 1 then they will convert to (base36) which consist of numbers from 0-9 and a-z in a lowercase format with the use of method name called .toString().

The zero and decimal point can be remove using the .slice() method, after that we will used a Math.random().toString(36).slice(2) to generate a random password so that i can’t create an empty array.

For uppercase letters we can use the same (method) with the use of .uppercase() in concatenation method.

Why Random Password Generator is important?

A password-generating program is important because it can present all of your credentials in a clear and concise manner.

As a result, you won’t have to remember hundreds of passwords except the generator login information.

The main goal of utilizing a password generator is to generate strong, random passwords for all of your accounts.

Advantages:

The advantages of utilizing a random password generator are obvious: a strong password created online may help you secure your personal and professional email accounts, social media accounts, WiFi encryption, banking, and financial and savings accounts.

In general, the more randomness a password contains, the more difficult it is to crack. Longer passwords are preferred because they are more likely to contain “randomness.”

Passwords are your computer’s and personal information’s first line of defense against unwanted access. Your computer will be safer from hackers and bad malware if your password is strong. For all accounts on your computer, you should use strong passwords.
