 ## Technical Context
 
-**Language/Version**: Python 3.11  
-**Primary Dependencies**: FastAPI, uvicorn, garminconnect, garth, fitbit, SQLAlchemy, Jinja2, psycopg2  
-**Storage**: PostgreSQL database for all data including configuration, health metrics, activity files, and authentication status information  
-**Testing**: pytest for unit and integration tests, contract tests for API endpoints  
-**Target Platform**: Linux server (containerized with Docker)  
-**Project Type**: Web application (backend API + web UI)  
-**Performance Goals**: Process 1000 activity files within 2 hours, sync weight data with 95% success rate, API responses under 3 seconds  
-**Constraints**: All sensitive data stored locally, offline-capable operation, secure storage of OAuth tokens

+The application handles Garmin's MFA flow automatically:
+1. When prompted for MFA, enter your Garmin credentials on the setup page
+2. If MFA is required, you'll receive a code via SMS or email
+3. Enter the code on the MFA verification page to complete authentication
