How to Show and Hide Password using React.js

When creating a form with a password input in your React.js application, you may want to give the user the option to either show or hide the password they have entered. This can be achieved by using the Material-UI library to create a toggle button for password visibility. In this article, we will walk through the steps on how to implement this feature in a React.js application using Material-UI.

Setting up the project

Before we can begin implementing the show and hide password feature, we need to set up a new React.js project with Material-UI. If you haven’t already installed Material-UI, you can do so by running the following command in your terminal:

    npm install @mui/material @emotion/react @emotion/styled
  

Once you have Material-UI installed, you can create a new React.js project by running the following command:

    npx create-react-app toggle-password-visibility
  

Implementing the toggle button

Now that we have our project set up, we can start implementing the show and hide password feature. First, we need to create a new component for our password input with a toggle button for password visibility. Here’s an example of what the component might look like:

    
      import React, { useState } from 'react';
      import { TextField, IconButton, InputAdornment } from '@mui/material';
      import { Visibility, VisibilityOff } from '@mui/icons-material';

      function PasswordInput() {
        const [showPassword, setShowPassword] = useState(false);

        const handleTogglePassword = () => {
          setShowPassword(!showPassword);
        };

        return (
          <TextField
            type={showPassword ? 'text' : 'password'}
            label="Password"
            InputProps={{
              endAdornment: (
                
                  
                    {showPassword ?  : }
                  
                
              )
            }}
          />
        );
      }

      export default PasswordInput;
    
  

In this example, we use the useState hook to keep track of the password visibility state. We then use the IconButton and InputAdornment components from Material-UI to create a toggle button for the password input field. When the user clicks on the toggle button, the handleTogglePassword function is called, which toggles the showPassword state between true and false, thus showing or hiding the password accordingly.

Using the PasswordInput component

Now that we have our PasswordInput component, we can use it in our form wherever we need a password input field. Here’s an example of how we might use the PasswordInput in a login form:

    
      import React from 'react';
      import PasswordInput from './PasswordInput';

      function LoginForm() {
        return (
          
            

              Email
              
            
            

              
            
            Login
          
        );
      }

      export default LoginForm;
    
  

Now, when the user types a password into the input field, they will have the option to show or hide the password using the toggle button. This provides a more user-friendly experience and can help prevent input errors when entering a password.

Conclusion

In this article, we have walked through the process of implementing a show and hide password feature in a React.js application using Material-UI. By using the IconButton and InputAdornment components from Material-UI, we were able to create a toggle button for password visibility, providing a more user-friendly experience for the form users. By following these steps, you can easily implement this feature in your own React.js applications.
