This article will show you how to Hide/Show passwords using JavaScript. While filling up a form, there comes a situation where we type a password and want to see what we have typed till now. To see that, there is a checkbox click on which makes the characters visible. In this article, we will add the toggle password feature using JavaScript.

Approach:

Create an HTML form that contains an input field of type password.
Create a checkbox that will be responsible for toggling.
Create a function that will respond to toggling when a user clicks on the checkbox.

Example:

Password is zambiatek. 
So, on typing it will show like this ************* 
And on clicking the checkbox it will show the characters: zambiatek.

        // Change the type of input to password or text
        function Toggle() {
