How to Implement Sign in with Apple for Your Firebase Web App

In today’s digital age, user authentication has become a vital aspect of application development. Among the various authentication methods, Sign in with Apple has gained popularity since its introduction in 2019. This feature allows users to log into web or mobile applications effortlessly using their Apple ID, mirroring one-click sign-in options found in services like Google or Facebook. In this article, we will explore how to integrate Sign in with Apple into your Firebase web application, simplifying the user experience while enhancing security.

Why Use Sign in with Apple?

  • Enhanced Privacy: Users can choose to hide their email addresses, providing an added layer of privacy.
  • Streamlined Access: Logging in with a single click simplifies the user’s entry into your app, reducing friction.
  • Apple Ecosystem Integration: Users within the Apple ecosystem may prefer this method, increasing user satisfaction.

Prerequisites for Integration

Before diving into the implementation process, there are a few requirements you need to satisfy:

  1. Apple Developer Account: You need to have an Apple Developer account, which costs about $99 per year.
  2. Firebase Project: Set up a Firebase project if you haven’t already.

Step-by-Step Guide to Implementing Sign in with Apple

Follow these detailed steps to successfully integrate Sign in with Apple into your Firebase web app:

Step 1: Configure Your App ID

  1. Access Apple Developer Portal: Log in to your Apple Developer Portal.
  2. Create or Update App ID: Create a new app ID or update an existing one to include the Sign in with Apple capability.

Step 2: Set Up a Service ID

  1. Create a Service ID: Navigate to the Identifiers section and create a new Service ID.
  2. Enter Hosting URLs: Configure the Service ID and input the hosting URLs from your Firebase project.
  3. Register Service ID: After entering all necessary information, register the Service ID.

Step 3: Domain Verification

  1. Download Verification File: Go back to the Service ID configuration and download the verification file provided by Apple.
  2. Upload to Firebase: Save this file in the well-known directory of your public hosting folder. Then, run the command firebase deploy from your terminal to upload the file to Firebase Hosting.
  3. Verify Ownership: Click on the verification button and ensure you receive a green checkmark, indicating that the domain has been verified successfully.

Step 4: Generate a Private Key

  1. Access Keys Section: Navigate to the Keys section on the Apple Developer Portal.
  2. Generate New Key: Create a new key dedicated to Apple sign-in and download the relevant file. Store this file securely as it contains sensitive information.

Step 5: Configure Firebase for Apple Sign-in

  1. Go to Firebase Console: Open the Firebase console and navigate to the Authentication tab.
  2. Enable Apple Sign-in: Click on the option to enable Apple sign-in, and fill in your Team ID along with the information from your private key.

Step 6: Add JavaScript Code

  1. Initialize Firebase: In your front-end app, ensure Firebase is initialized.
  2. Create Sign-in Function: Define an async function called signInWithApple.
const provider = new firebase.auth.AppleAuthProvider();

async function signInWithApple() {
    try {
        const result = await firebase.auth().signInWithPopup(provider);
        // User is signed in, and you now have access to the user data.
        console.log("User signed in: ", result.user);
    } catch (error) {
        console.error("Error during sign-in: ", error);
    }
}
  1. Prompt User to Sign-in: This function will open a popup prompting the user to log in with their Apple ID.

Conclusion

By implementing the Sign in with Apple feature in your Firebase web application, you not only provide an enhanced user experience but also make your application more secure by leveraging Apple’s solid privacy features. This guide offers a streamlined approach to authentication, ensuring that your app adheres to modern standards while remaining appealing to users.
