How can I implement authentication in a React app?

You can implement authentication in a React app using libraries like Firebase, Auth0, or by creating your own backend with JWT.

What are the steps to set up Firebase authentication?

First, create a Firebase project, then install Firebase SDK in your React app, and finally configure authentication methods in the Firebase console.

Can you show me a code example for using Firebase authentication?

Sure! Here's a simple example:

import firebase from 'firebase/app';
import 'firebase/auth';

const firebaseConfig = { /* your config */ };
firebase.initializeApp(firebaseConfig);

const signIn = async (email, password) => {
  try {
    const userCredential = await firebase.auth().signInWithEmailAndPassword(email, password);
    console.log('User signed in:', userCredential.user);
  } catch (error) {
    console.error('Error signing in:', error);
  }
};
