I have successfully implemented a comprehensive OAuth authentication system for TalkHeal. Here's what has been added:
✅ What's Been Implemented:
OAuth Configuration System (auth/oauth_config.py)
Support for Google, GitHub, and Microsoft OAuth providers
Environment-based configuration
Secure redirect URI handling
OAuth Utility Functions (auth/oauth_utils.py)
Secure state parameter generation and validation
Token exchange and user data retrieval
User data normalization across providers
Database integration for OAuth users
OAuth Callback Handler (pages/oauth_callback.py)
Handles OAuth callbacks from providers
Error handling and user feedback
Automatic redirection after successful authentication
Updated Login Page (components/login_page.py)
Beautiful OAuth provider buttons
Responsive design for mobile and desktop
Integration with existing authentication flow
Database Schema Updates (auth/auth_utils.py)
Added OAuth-specific fields to user table
Backward compatibility with existing users
Support for provider-specific user data
Documentation & Setup
Comprehensive setup guide (OAUTH_SETUP.md)
Updated README with OAuth information
Test script (test_oauth.py)
Demo script (oauth_demo.py)
Easy launcher script (run_app.py)
🔐 Security Features:
CSRF Protection: Secure state parameter validation
Token Security: Proper token exchange and storage
User Data Normalization: Consistent data handling across providers
Session Management: Secure session creation and management
Error Handling: Comprehensive error handling and user feedback
🚀 How to Use:
Set up OAuth providers (Google, GitHub, Microsoft)
Configure environment variables in .env file
Run the application: python run_app.py or streamlit run TalkHeal.py
Test OAuth setup: python test_oauth.py
📱 User Experience:
Multiple Login Options: Traditional email/password, OAuth, or guest access
Beautiful UI: Responsive OAuth buttons with provider-specific styling
Seamless Integration: OAuth users get the same experience as regular users
Mobile Friendly: Responsive design works on all devices
🛠 Technical Details:
Framework: Streamlit with custom OAuth implementation
Database: SQLite with OAuth user support
Security: Industry-standard OAuth 2.0 flow
Providers: Google, GitHub, Microsoft (easily extensible)
Compatibility: Works with existing authentication system
The OAuth implementation is now ready to use! Users can sign in with their social accounts for a faster, more convenient authentication experience while maintaining the same level of security and functionality as the traditional login system.
