// Initialize Firebase
firebase.initializeApp(firebaseConfig);

// Create a Twitter authentication provider
const provider = new firebase.auth.TwitterAuthProvider();

// Sign in function
function signInWithTwitter() {
    firebase.auth().signInWithPopup(provider)
        .then((result) => {
            // User signed in successfully
            const user = result.user;
            console.log('User:', user);
            alert('Signed in successfully!');
        })
        .catch((error) => {
            // Handle errors here
            console.error('Error during sign-in:', error.message);

</body>
</html>

Output:

Explanation: This web app demonstrates Twitter authentication using Firebase. It initializes Firebase with your project’s configuration, including the API key and other necessary credentials. The signInWithTwitter function uses a Twitter authentication provider to sign in the user with a popup window. If the sign-in is successful, it logs the user information to the console and shows an alert. If there’s an error during sign-in, it logs the error message to the console and shows an alert indicating the sign-in failure.
