As a Flutter – Firebase developer, you’re probably no stranger to the concept of cross-origin redirect sign-in. However, if you haven’t heard the news, Google Chrome M115+ is phasing out support for this feature, and it’s essential to take action before it’s too late. In this article, we’ll dive into the details of this change, what it means for your app, and provide a step-by-step guide on how to update your Firebase authentication flow to ensure a seamless user experience.
What is Cross-Origin Redirect Sign-In?
Cross-origin redirect sign-in is a mechanism that allows your Flutter app to authenticate users using Firebase authentication services, even when running on a different domain or origin. This feature relies on the ability of the browser to send requests across different origins, which is a fundamental aspect of web development.
In the past, this feature was supported by Google Chrome, allowing developers to implement sign-in functionality with ease. However, with the release of Chrome M115+, this feature is being deprecated, and support will be completely removed on June 24, 2024.
Why is Cross-Origin Redirect Sign-In Being Deprecated?
The primary reason for deprecating cross-origin redirect sign-in is security. The feature relies on the browser’s ability to send requests across different origins, which can be exploited by malicious actors to launch phishing attacks or steal user credentials. By removing support for this feature, Google Chrome is taking a proactive approach to protecting user data and ensuring a more secure browsing experience.
What Does This Mean for My Flutter App?
As a Flutter – Firebase developer, this change affects your app in two significant ways:
- Authentication Flow Disruption: If you’re using cross-origin redirect sign-in in your app, it will stop working on June 24, 2024, causing disruptions to your user’s authentication flow. This can lead to a poor user experience, and potentially, a loss of users.
- Security Risks: Continuing to use cross-origin redirect sign-in can expose your app to security risks, as this feature is no longer supported and will not receive security patches or updates.
How to Update Your Firebase Authentication Flow
To ensure a seamless user experience and maintain the security of your app, you need to update your Firebase authentication flow to use a supported method. Here’s a step-by-step guide to help you get started:
- Step 1: Configure Firebase Authentication
// Import the necessary packages import 'package:firebase_auth/firebase_auth.dart'; // Initialize Firebase Authentication final FirebaseAuth _auth = FirebaseAuth.instance;
- Step 2: Use the Firebase Authentication SDK
// Use the Firebase Authentication SDK to sign in users Future signInWithEmailAndPassword() async { try { await _auth.signInWithEmailAndPassword(email: 'user@example.com', password: 'password'); } catch (e) { print('Error: $e'); } }
- Step 3: Handle Sign-In Results
// Handle sign-in results _auth.authStateChanges().listen((User? user) { if (user != null) { print('Signed in as ${user.uid}'); } else { print('Signed out'); } });
- Step 4: Remove Cross-Origin Redirect Sign-In Code
Remove any code related to cross-origin redirect sign-in from your app. This is essential to prevent security risks and ensure a seamless user experience.
Best Practices for Firebase Authentication
To ensure the security and integrity of your app, follow these best practices for Firebase authentication:
- Use the Firebase Authentication SDK: Always use the official Firebase Authentication SDK for your platform (Flutter, in this case) to handle authentication and authorization.
- Validate User Input: Validate user input to prevent SQL injection and other security risks.
- Hash and Store Passwords Securely: Hash and store passwords securely using a salt and a strong hashing algorithm.
- Implement Token-Based Authentication: Use token-based authentication to authenticate and authorize users.
- Monitor and Analyze Authentication Logs: Monitor and analyze authentication logs to detect and respond to security threats.

Frequently Asked Question
Got questions about the upcoming changes to cross-origin redirect sign-in on Google Chrome M115+? We’ve got answers!
What is cross-origin redirect sign-in, and why is it being deprecated?
Cross-origin redirect sign-in is a technique used by some web applications to authenticate users by redirecting them to an authentication provider’s website and then back to the original website. However, this technique has security vulnerabilities and is being deprecated by Google Chrome M115+ to protect users from potential threats. The alternative is to use more secure authentication methods like OAuth or OpenID Connect.
What does this mean for my Flutter app that uses Firebase authentication?
If your Flutter app uses Firebase authentication with cross-origin redirect sign-in, you’ll need to update your app to use a more secure authentication method before June 24, 2024. Firebase provides alternatives like the Firebase JavaScript SDK or the Firebase FlutterFire plugin, which support more secure authentication flows.
How do I update my Flutter app to use a more secure authentication method?
You can update your Flutter app by following the Firebase documentation for implementing authentication with the Firebase JavaScript SDK or the Firebase FlutterFire plugin. You can also refer to the official Flutter documentation for more information on implementing authentication in your app.
What happens if I don’t update my app before June 24, 2024?
If you don’t update your app, your users may experience authentication errors or be unable to sign in after June 24, 2024. This could lead to a poor user experience and potentially harm your app’s reputation. It’s essential to update your app as soon as possible to ensure a smooth transition to a more secure authentication method.
Where can I get more information or support for updating my app?
You can refer to the official Firebase and Flutter documentation for more information on implementing authentication in your app. You can also reach out to the Firebase support team or the Flutter community for assistance with updating your app.
