📅 Completion Date: August 26, 2025

🎯 Story 3.2: Frontend Authentication Integration - COMPLETE

Summary

The YouTube Summarizer now has a fully functional, production-ready authentication system integrating both backend (Story 3.1) and frontend (Story 3.2) components. Users can register, login, manage their sessions, and access protected features with a seamless experience.

✅ Completed Implementation

Backend (Story 3.1)

JWT Authentication: Access and refresh token system
User Management: Registration, login, logout endpoints
Email Verification: Verification flow with secure tokens
Password Reset: Secure password recovery system
Database Models: User, RefreshToken, APIKey models
Security: bcrypt hashing, token rotation, secure sessions

Frontend (Story 3.2)

AuthContext: Global authentication state management
Protected Routes: Route protection with authentication checks
Authentication Forms: Login, Register, Password Reset forms
Token Management: Automatic refresh before expiry
User Interface: UserMenu with logout, profile navigation
Error Handling: Comprehensive error states and user feedback

🏗️ Architecture

Frontend                          Backend
