Step 1: Create a React project with Bootstrap
Open your terminal and run the following command to scaffold your React project using Create React App with Bootstrap template:

npx create-react-app my-project
cd my-project
npm install bootstrap@5.0.0

Step 2: Install FaceIO library
Create a FaceIO account and get the required credentials, such as the FaceIO CDN link and public ID, from the FaceIO console.
Open the index.html file in your project and add the FaceIO CDN link:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>FaceIO Authentication</title>
  <!-- Add Bootstrap CSS -->
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0/dist/css/bootstrap.min.css">
  <!-- Add FaceIO CDN -->
  <script src="https://cdn.face.io/faceio.js"></script>
</head>
<body>
  <div id="root"></div>
  <script src="./src/index.js"></script>
</body>
</html>

Step 3: Create a React component for authentication
Replace the contents of src/App.js with the following code:

import React, { useEffect } from 'react';

const App = () => {
  useEffect(() => {
    const initFaceIO = async () => {
      try {
        const faceIO = new FaceIO('YOUR_FACEIO_ID');
        await faceIO.init();
        console.log('FaceIO initialized successfully');
      } catch (error) {
        console.error('Failed to initialize FaceIO:', error);
      }
    };
    initFaceIO();
  }, []);

  const handleRegister = async () => {
    try {
      const faceIO = new FaceIO('YOUR_FACEIO_ID');
      const enrollOptions = {
        locale: 'auto',
        payload: { email: 'user@example.com' }
      };
      const userInfo = await faceIO.enroll(enrollOptions);
      console.log('User registered successfully:', userInfo);
    } catch (error) {
      console.error('Failed to register user:', error);
    }
  };

  const handleLogin = async () => {
    try {
      const faceIO = new FaceIO('YOUR_FACEIO_ID');
      const userData = await faceIO.authenticate();
      console.log('User authenticated successfully:', userData);
    } catch (error) {
      console.error('Failed to authenticate user:', error);
    }
  };

  return (
    <div className="container">
      <h1 className="my-4">FaceIO Authentication</h1>
      <div className="d-grid gap-2 col-6 mx-auto my-4">
        <button className="btn btn-primary" onClick={handleRegister}>
          Register
        </button>
        <button className="btn btn-success" onClick={handleLogin}>
          Log In
        </button>
      </div>
    </div>
  );
};

export default App;

Step 4: Style the application using Bootstrap
Open the src/index.js file and replace its contents with the following code:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

import 'bootstrap/dist/css/bootstrap.min.css';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

Step 5: Start the development server
Save all the changes and start the development server:
npm start
Now, you can open your browser and access the application at http://localhost:3000. The page will display buttons for user registration and login. When clicked, the respective functions will be triggered, calling FaceIO functions to perform enrollment and authentication.
Remember to replace 'YOUR_FACEIO_ID' in the code with your actual FaceIO ID obtained from the FaceIO console.
Note: This tutorial assumes you have the necessary FaceIO library and credentials. Please refer to the official FaceIO documentation for more details on the library and its usage.
Managing FACEIO application after implementation

- Addressing security

FACEIO offers a range of core security features to enhance the security of your applications. These features include rejecting weak PIN codes during enrollment, preventing duplicate enrollments, detecting face spoofing attempts, forbidding minors from enrolling, asking for PIN codes during authentication, enforcing PIN code uniqueness, handling obscured and partially masked faces, and verifying HTTP request headers. Additional security measures include restricting widget instantiation to authorized domain names and countries, enabling webhooks for real-time event notifications, and configuring specific security settings through the Application Manager.
