Hello friend, hope you are doing awesome, today in this blog I have shown How to make a Password Strength Checker using HTML CSS, and JavaScript, as you know there are lots of JavaScript projects that I have created like email validation, password, and confirm password checker. As like them, this project is also relevant.

In simple and easy language, Password Strenght Checker is the program that tests our password and shows how strong our password is. This type of program helps users to create theirs strong passwords, which really helps to prevent hacking.

Let’s have a look at the given image of our program’s Password Strength Checker. There are three input fields with some characters. As you can see the first field shows our entered password is weak because i have used only alphabet letters, the second field shows the entered password is medium because I have added some numbers with alphabet letters and the last input field shows that our password is strong because I have entered alphabet letter, number, and one special character.

Now you have to know, to create a strong password we need to combine alphabet letters (capital letters and small letters), some numbers (like 1,2,3….9), and some special characters(like @,! $,%,#,&,*).

I hope now you got the basic and theoretical meaning of the Password Strength Checker, rather than theory I would highly recommend you to watch the given video tutorial of this project because in the video you will get the opportunity to see the real example of how this program checks the password and all the HTML CSS and JavaScript code that I have used to create this Password Strength Checker.

Password Strength Checker | HTML CSS & JavaScript

 

I have provided all the HTML CSS and JavaScript source code that I used to create this Password Strength Checker below, before jumping into the source code, you need to know some important points of this program.

As you have seen on the given video tutorial of this Password strength checker. At first, we saw a blank password field with a grey border. When I entered the character, it’s started to check and according to the character border, text, and eye icon color changed, that makes more beautiful, isn’t it?. Also by clicking on the eye button we can see our character easily.

This UI design is made by HTML and CSS and to show password strength and to show or hide passwords, I have used JavaScript code.

You can make this Password Strength Checker by watching a video tutorial and following the codes or you can take all the HTML CSS and javascript code forms below:

Hello friend, hope you are doing well, today are going to create some useful project like Check Password & Confirm Password using HTML CSS and JavaScript. There are lots of JavaScript projects I have created for beginners to advance, I am sure these will be also very awesome and useful projects.

Check password and confirm password features are mostly used, while we are going to set our new password to login into a website. It helps users to remember their passwords because they have to match the password in both input fields.

Let’s have a look at the given image of your projects [Check Password & Confirm Password], The upper input field is inactive condition but the second input field and button are disabled. It means we can not enter characters on the second input field and we cannot click on the button. When the user enters eight or more than eight characters on the first input field then second input field and button will activate. After clicking on the button we know that our password matched or not.

Along with this, I have added some animation on the input field, that will happen when we focus on the input field, and also I have added password show or hide features while we click on the eye icon.

Rather than words, I would like to show you the real demo of this program [Check Password & Confirm Password using JavaScript], Now we are going to watch the video tutorial that is provided below. By watching the live video tutorial we will see the real demo of this program and get the idea of how all the HTML CSS and JavaScript codes are working properly and perfectly.

Check Password & Confirm Password in JavaScript

I have provided all the HTML CSS and JavaScript source code that I have used to create this program Check Password & Confirm Password, Password show and hide while clicking on the eye icon and Input field animation on focus. Before jumping into the source code file, you need to know some basic concepts of this program and tutorial.

As you have seen on the video tutorial of this program [Check Password & Confirm Password using JavaScript]. At first, we can only focus and type in the first input field. The second input field and button are in disabled form. When I type eight words on the first input field then the second field is activated and the button also.

At first, our typed password is in dot form, after I clicked on the eye icon our password converted into alphabet or number form. By clicking on the button We knew that you have entered a similar password or something different.

To make input field animation and UI design I have used only HTML and CSS. And to make the password show and hide while clicking on the eye button and to check the password and confirm the password I used JavaScript.
