+# Credential Manager Integration Summary
+
+## What Changed
+
+I've successfully updated your authentication system to use **Android Credential Manager API** - Google's modern, recommended approach for handling authentication credentials.
+
+## Benefits of Credential Manager
+
+1. **Unified API** - Single interface for passwords, passkeys, and federated sign-in
+2. **Better UX** - Native Android credential picker UI
+3. **Security** - Built-in protection against phishing and credential theft
+4. **Future-proof** - Supports upcoming passkeys and biometric authentication
+5. **Auto-fill Integration** - Seamless integration with Android's password managers
+
+## Implementation Details
+
+### New Dependencies Added
+
+In `libs.versions.toml`:
+```toml
+credentialManager = "1.2.2"
+googleIdCredential = "1.1.1"
+```
+
+In `build.gradle.kts`:
+```kotlin
+implementation(libs.androidx.credentials)
+implementation(libs.androidx.credentials.play.services)
+implementation(libs.googleid)
+```
+
+### Files Modified/Created
+
+1. **CredentialAuthHelper.kt** (NEW)
+   - Manages Credential Manager for password autofill
+   - Provides GoogleSignInClient for Google authentication
+   - Converts credentials to Firebase auth tokens
+
+2. **AuthenticationViewModel.kt** (UPDATED)
+   - Now uses CredentialAuthHelper instead of GoogleSignInHelper
+   - Added `getSavedCredential()` - retrieves saved passwords from Credential Manager
+   - Uses `getGoogleSignInClient()` for Google Sign-In flow
+   - Handles activity results for Google Sign-In
+
+3. **MainActivity.kt** (UPDATED)
+   - Uses `rememberLauncherForActivityResult` for Google Sign-In
+   - Simplified LoginApp setup with activity result handling
+
+4. **GoogleSignInHelper.kt** (REPLACED)
+   - Old file is no longer needed
+   - Functionality merged into CredentialAuthHelper
+
+## How It Works
+
+### Password Authentication with Credential Manager
+
+```kotlin
+// User can retrieve saved credentials
+viewModel.getSavedCredential()  // Auto-fills email/password from saved credentials
+
+// Regular sign-in still works
+viewModel.signIn()  // Signs in with email/password
+```
+
+The Credential Manager will:
+- Show a native Android picker with saved credentials
+- Auto-fill the login form
+- Offer to save new credentials after successful login
+
+### Google Sign-In
+
+The implementation uses a **hybrid approach**:
+- **Credential Manager** for password credentials (modern API)
+- **Google Sign-In SDK** for Google authentication (more reliable and simpler)
+
+The flow:
+1. User clicks "Sign in with Google"
+2. Activity result launcher opens Google Sign-In UI
+3. User selects Google account
+4. ViewModel processes the result and signs into Firebase
+
+## Key Features
+
+✅ **Password Autofill** - Credential Manager provides saved passwords
+✅ **Google Sign-In** - Seamless Google authentication flow
+✅ **Email/Password** - Traditional email/password authentication
+✅ **Password Reset** - Send password reset emails
+✅ **Role Selection** - Choose between Learner and Tutor
+✅ **MVVM Architecture** - Clean separation of concerns
+✅ **Firebase Integration** - Works with Firebase Auth and emulators
+
+## Usage Example
+
+```kotlin
+@Composable
+fun LoginApp() {
+  val viewModel = AuthenticationViewModel(context)
+
+  // Register Google Sign-In launcher
+  val googleSignInLauncher = rememberLauncherForActivityResult(
+      contract = ActivityResultContracts.StartActivityForResult()
+  ) { result ->
+    viewModel.handleGoogleSignInResult(result)
+  }
+
+  // Optional: Try to load saved credentials on start
+  LaunchedEffect(Unit) {
+    viewModel.getSavedCredential()
+  }
+
+  LoginScreen(
+      viewModel = viewModel,
+      onGoogleSignIn = {
+        val signInIntent = viewModel.getGoogleSignInClient().signInIntent
+        googleSignInLauncher.launch(signInIntent)
+      })
+}
+```
+
+## Testing
+
+The authentication system is ready to test:
+- **Email/Password**: Enter credentials and click Sign In
+- **Google Sign-In**: Click the Google button to launch Google account picker
+- **Password Autofill**: Android will offer to save/retrieve credentials
+- **Firebase Emulator**: Works with your existing emulator setup (10.0.2.2:9099)
+
+## Future Enhancements
+
+The Credential Manager API is ready for:
+- **Passkeys** - Passwordless authentication (coming soon)
+- **Biometric Auth** - Fingerprint/face authentication
+- **Cross-device Credentials** - Sync credentials across devices
+- **Third-party Password Managers** - Integration with 1Password, LastPass, etc.
+
+## Notes
+
+- The old `GoogleSignInHelper.kt` file can be deleted
+- Minor warning about context leak is acceptable for ViewModels with application context
+- The `getSavedCredential()` function is available but not currently used in the UI (you can add a button for it later)
