+### Google Authentication
+
+To configure Google Sign-In for your app, follow these steps:
+
+#### 1. Enable Google Authentication in Firebase Console
+
+In the **Firebase Console**, go to **Authentication > Sign-in method**, select **Google**, and enable it. Click **Save** to confirm.
+
+#### 2. Add SHA-1 Key for Android
+
+For Android apps, generate your SHA-1 key by following the instructions in the [Google Developer Guide](https://developers.google.com/android/guides/client-auth). Then, open the **Firebase Console > Project Settings**, scroll to **Your Apps** section, select your Android app, and under **SHA certificate fingerprints**, click **Add fingerprint**. Paste the SHA-1 key and click **Save**.

+![add-sha-1-key.avif](imgs/add-sha-1-key.avif)
+
+#### 3. Update Firebase Configuration Files
+
+After enabling Google Authentication, download the latest Firebase configuration files, i.e., `google-services.json` for Android and `GoogleService-Info.plist` for iOS, from the Firebase Console, and then upload these files to your Dreamflow app at the following location:
+
+- Place the `google-services.json` file inside your project at `android/app/`.
+- Place the `GoogleService-Info.plist` file inside `ios/Runner/`.
+
+![update-firebase-configuration-file.avif](imgs/update-firebase-configuration-file.avif)
+
+#### 4. Add Google Authentication Code
+
+You can add the Google sign-in code manually or let the Dreamflow Agent generate it for you. Here’s the **sample agent prompt** you can try:
+
+```jsx
+Generate Google Sign-In authentication code for both mobile and web using the latest versions of firebase_auth and google_sign_in Dart packages.
+```
+#### 5. Add Authorized Domain
+
+If you’re building for the web and want to test authentication while running your app in Dreamflow, follow the steps in the [Add Authorized Domain](#add-authorized-domain) section to add your Dreamflow preview domain to the Authorized Domains list in the Firebase Console.
+
+### Facebook Authentication
+
+To enable Facebook login in your app, follow the steps below:
+
+#### 1. Set Up a Facebook Developer App
+
+Before getting started, create and configure your [**Facebook Developer App**](https://developers.facebook.com/apps/). During setup, enable the **Facebook Login** product and complete the basic configuration.
+
+#### 2. Enable Facebook Authentication in Firebase Console
+
+1. In the **Firebase Console**, go to **Authentication > Sign-in method**. Select **Facebook** and enable it.
+2. You’ll be prompted to enter your **App ID** and **App Secret**, which you can find in your Facebook Developer App Dashboard under **App** **Settings > Basic**.
+
+    ![add-app-details.avif](imgs/add-app-details.avif)
+
+3. Copy the **OAuth Redirect URI** displayed in Firebase and add it to your Facebook app settings under **Facebook Login > Settings > Valid OAuth Redirect URIs**.
+
+    ![add-facebook-uri.avif](imgs/add-facebook-uri.avif)
+
+4. Click **Save** in Firebase once everything is configured.
+
+#### 3. Add Facebook Authentication Code
+
+You can add the Facebook sign-in code manually or let the Dreamflow Agent generate it for you. Here’s the **sample agent prompt** you can try:
+
+```jsx
+Generate Facebook authentication code for both mobile and web using the latest versions of firebase_auth and flutter_facebook_auth Dart packages.
+```
+
+#### 4. Configure Platform-Specific Code
+
+Once the authentication code is added, you’ll need to configure your project for **Android** and **iOS** to ensure the Facebook sign-in works properly.
+
+- **For Android:** Follow the setup guide in the [Facebook Android configuration documentation](https://facebook.meedu.app/docs/7.x.x/android).
+- **For iOS:** Refer to the [Facebook iOS configuration guide](https://facebook.meedu.app/docs/7.x.x/ios).
+
+#### 5. Add Authorized Domain
+
+If you’re building for the web and want to test authentication while running your app in Dreamflow, follow the steps in the [Add Authorized Domain](#add-authorized-domain) section to add your Dreamflow preview domain to the **Authorized Domains** list in the Firebase Console.
+
+### Add Authorized Domain
+
+If you’re building for the web and want to test authentication while running your app in Dreamflow, you must add your Dreamflow preview domain to the **Authorized Domains** list in the Firebase Console.
+
+To add authorized domain:
+
+1. Open **Developer Tools** in your browser; press **`Ctrl + Shift + J`** (Windows/Linux) or **`Cmd + Option + J`** (Mac) to open it directly in **Google Chrome**.
+2. In the **Console** tab, press **Ctrl + F** (or **Cmd + F** on Mac) and search for `dreamflow.cloud`.
+Locate the log entry that contains a URL like: `wss://summer-firefly-vuh34ynj.mum0.dreamflow.cloud`
+3. Copy the domain part — for example: `summer-firefly-vuh34ynj.mum0.dreamflow.cloud`
+4. Go to the **Firebase Console** → **Authentication** → **Settings** → **Authorized Domains**. Click **Add Domain**, paste the copied Dreamflow domain, and click **Save**.
+5. Reload and test your app.

 ## Add Sample Data to Firebase
 
 Dreamflow lets you add sample data to your Firebase project for easier development and testing. The generated data follows your app’s schema, so you can quickly check how your app works with populated users, collections, and documents.
