+# Zoho Authentication WebView
+
+This directory contains the Zoho authentication implementation using React Native WebView.
+
+## Files
+
+- `ZohoAuth.tsx` - Main WebView component for Zoho OAuth authentication
+- `ZohoAuthExample.tsx` - Example implementation showing how to use the ZohoAuth component
+- `LoginScreen.tsx` - Existing login screen (can be extended to include Zoho auth)
+
+## ZohoAuth Component
+
+The `ZohoAuth` component provides a WebView-based authentication flow for Zoho services.
+
+### Features
+
+- ✅ WebView-based OAuth flow
+- ✅ Error handling and retry functionality
+- ✅ Loading states and user feedback
+- ✅ Theme integration with the app's design system
+- ✅ TypeScript support with proper type definitions
+- ✅ Responsive design with proper styling
+
+### Usage
+
+```tsx
+import React, { useState } from 'react';
+import { Modal } from 'react-native';
+import ZohoAuth from './ZohoAuth';
+
+const MyComponent = () => {
+  const [showZohoAuth, setShowZohoAuth] = useState(false);
+
+  const handleAuthSuccess = (authData) => {
+    console.log('Auth successful:', authData);
+    // Handle successful authentication
+    setShowZohoAuth(false);
+  };
+
+  const handleAuthError = (error) => {
+    console.error('Auth failed:', error);
+    // Handle authentication error
+    setShowZohoAuth(false);
+  };
+
+  return (
+    <>
+      <Button title="Login with Zoho" onPress={() => setShowZohoAuth(true)} />
+      
+      <Modal visible={showZohoAuth} animationType="slide">
+        <ZohoAuth
+          onAuthSuccess={handleAuthSuccess}
+          onAuthError={handleAuthError}
+          onClose={() => setShowZohoAuth(false)}
+        />
+      </Modal>
+    </>
+  );
+};
+```
+
+### Configuration
+
+Before using the component, you need to configure your Zoho OAuth credentials:
+
+1. **Update the configuration in `ZohoAuth.tsx`:**
+
+```typescript
+const ZOHO_CONFIG = {
+  CLIENT_ID: 'YOUR_ZOHO_CLIENT_ID',           // Your Zoho OAuth app client ID
+  REDIRECT_URI: 'YOUR_REDIRECT_URI',          // Your app's redirect URI
+  SCOPE: 'ZohoProjects.projects.READ,ZohoProjects.tasks.READ,ZohoProjects.timesheets.READ',
+  RESPONSE_TYPE: 'code',
+  ACCESS_TYPE: 'offline',
+  PROMPT: 'consent',
+};
+```
+
+2. **Set up your Zoho OAuth application:**
+   - Go to [Zoho Developer Console](https://api-console.zoho.com/)
+   - Create a new OAuth application
+   - Set the redirect URI to match your app's scheme (e.g., `com.yourapp://oauth/callback`)
+   - Copy the Client ID to the configuration
+
+3. **Configure deep linking in your app:**
+   - Add URL scheme handling to your app's configuration
+   - Ensure the redirect URI matches your app's scheme
+
+### Props
+
+| Prop | Type | Required | Description |
+|------|------|----------|-------------|
+| `onAuthSuccess` | `(authData: ZohoAuthData) => void` | No | Callback when authentication succeeds |
+| `onAuthError` | `(error: string) => void` | No | Callback when authentication fails |
+| `onClose` | `() => void` | No | Callback when user closes the auth flow |
+
+### Auth Data Structure
+
+```typescript
+interface ZohoAuthData {
+  accessToken: string;      // OAuth access token
+  refreshToken?: string;    // OAuth refresh token (if available)
+  expiresIn?: number;       // Token expiration time in seconds
+  scope?: string;           // Granted scopes
+  tokenType?: string;       // Token type (usually 'Bearer')
+}
+```
+
+### Error Handling
+
+The component handles various error scenarios:
+
+- Network connectivity issues
+- Invalid OAuth configuration
+- User cancellation
+- Zoho API errors
+- WebView loading errors
+
+All errors are passed to the `onAuthError` callback with descriptive error messages.
+
+### Styling
+
+The component uses the app's theme system and automatically adapts to light/dark modes. It includes:
+
+- Consistent color scheme
+- Proper spacing and typography
+- Loading indicators
+- Error states with retry options
+- Responsive design
+
+### Security Considerations
+
+- The component uses OAuth 2.0 authorization code flow
+- Authorization codes should be exchanged for access tokens on your backend server
+- Never store sensitive tokens in the app's local storage without encryption
+- Use secure storage solutions for token persistence
+
+### Example Integration
+
+See `ZohoAuthExample.tsx` for a complete example of how to integrate the ZohoAuth component into your app, including:
+
+- Modal presentation
+- Success/error handling
+- UI state management
+- User feedback
+
+## Dependencies
+
+- `react-native-webview` - For the WebView component
+- `react-native-vector-icons` - For icons
+- `@shared/styles/useTheme` - For theme integration
+
+## Next Steps
+
+1. Configure your Zoho OAuth credentials
+2. Set up deep linking in your app
+3. Implement backend token exchange
+4. Add token storage and refresh logic
+5. Integrate with your app's authentication flow
