How can I implement authentication in my React Native app using Firebase?

To implement authentication in your React Native app using Firebase, you'll need to set up Firebase in your project and use the Firebase Authentication module. Have you already created a Firebase project?

Yes, I have a Firebase project set up. What are the next steps?

Great! Next, install the Firebase SDK in your React Native app. You can do this by running npm install @react-native-firebase/app @react-native-firebase/auth. After that, you can start implementing authentication methods like email/password or Google sign-in.

How do I set up email/password authentication?

To set up email/password authentication, use the createUserWithEmailAndPassword method from Firebase Auth. Here's a quick example:

import auth from '@react-native-firebase/auth';

const signUp = async (email, password) => {
  try {
    await auth().createUserWithEmailAndPassword(email, password);
    console.log('User account created & signed in!');
  } catch (error) {
    console.error(error);
  }
};
