How to show and hide Password in ReactJS?

Password can be shown to the user by adding a feature of the eye icon so that the user can see the password. Material UI for React has this component available for us and it is very easy to integrate. We can use some core material Component in ReactJS using the following approach.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command:

cd foldername

Step 3: After creating the ReactJS application, Install the material-ui modules using the following command:

npm install @material-ui/core
npm install @material-ui/icons

Project Structure: It will look like the following.

Project Structure

App.js: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Javascript

import React from "react";
import IconButton from "@material-ui/core/IconButton";
import InputLabel from "@material-ui/core/InputLabel";
import Visibility from "@material-ui/icons/Visibility";
import InputAdornment from "@material-ui/core/InputAdornment";
import VisibilityOff from "@material-ui/icons/VisibilityOff";
import Input from "@material-ui/core/Input";

const App = () => {
  const [values, setValues] = React.useState({
    password: "",
    showPassword: false,
  });

  const handleClickShowPassword = () => {
    setValues({ ...values, showPassword: !values.showPassword });
  };

  const handleMouseDownPassword = (event) => {
    event.preventDefault();
  };

  const handlePasswordChange = (prop) => (event) => {
    setValues({ ...values, [prop]: event.target.value });
  };

  return (
    <div
      style={{
        marginLeft: "30%",
      }}
    >
      <h4>How to show and hide password in ReactJS?</h4>
      <InputLabel htmlFor="standard-adornment-password">
        Enter your Password
      </InputLabel>
      <Input
        type={values.showPassword ? "text" : "password"}
        onChange={handlePasswordChange("password")}
        value={values.password}
        endAdornment={
          <InputAdornment position="end">
            <IconButton
              onClick={handleClickShowPassword}
              onMouseDown={handleMouseDownPassword}
            >
              {values.showPassword ? <Visibility /> : <VisibilityOff />}
            </IconButton>
          </InputAdornment>
        }
      />
    </div>
  );
};

export default App;

Step to Run Application: Run the application using the following command from the root directory of the project.
