Backend changes (Action 5.1.1.1):
- Set access_token cookie in Login, Register, and Refresh handlers
- Cookie uses same configuration as refresh_token (httpOnly, Secure, SameSite)
- Expiry matches AccessTokenTTL (5 minutes)
- Update logout handler to clear access_token cookie
Backend middleware (Action 5.1.1.1):
- Update auth middleware to read access token from cookie first
- Fallback to Authorization header for backward compatibility
- Update OptionalAuth with same cookie-first logic
Frontend changes (Actions 5.1.1.2 & 5.1.1.3):
- Remove localStorage token storage from TokenStorage service
- TokenStorage now returns null for getAccessToken/getRefreshToken (httpOnly cookies not accessible)
- Remove Authorization header logic from API client
- Remove token expiration checks (can't check httpOnly cookies from JS)
- Update AuthContext to remove localStorage usage
- Update tokenRefresh to work without reading tokens from JS
- Simplify refresh logic: periodic refresh every 4 minutes (no expiration checks)
Security improvements:
- Access tokens no longer exposed to XSS attacks (httpOnly cookies)
- Tokens automatically sent with requests via withCredentials: true
- Backend reads tokens from cookies, not Authorization headers
- All users will need to re-login after deployment (breaking change)
Breaking change: All users must re-login after deployment
