# Phase 1 Plan 7: Password Reset Navigation and Deep Linking Summary

**Complete password reset navigation system with URL parameter extraction and deep linking support across mobile and web platforms**

## Performance

- **Duration:** 10 minutes
- **Started:** 2026-01-28T17:10:56Z
- **Completed:** 2026-01-28T17:20:43Z
- **Tasks:** 2
- **Files modified:** 7

## Accomplishments
- Integrated password reset routes into the main router with deep linking support
- Added URL parameter extraction for reset tokens and email addresses
- Updated login and signup pages with functional "Forgot Password?" links
- Enhanced password reset confirmation page to handle deep linking parameters
- Updated password update page to extract and use reset tokens from URLs
- Added proper navigation guards to allow password reset routes regardless of authentication state
- Created comprehensive integration tests for password reset flow verification

## Task Commits

Each task was committed atomically:

1. **Task 1: Integrate password reset with navigation** - `680ecdc` (feat)
2. **Task 2: Update pages with password reset links** - `53329c9` (feat)

**Plan metadata:** Not yet committed (docs: complete plan)

## Files Created/Modified
- `lib/core/router/app_router.dart` - Added password reset routes, deep linking support, URL parameter extraction helpers
- `lib/features/authentication/presentation/pages/login_page.dart` - Updated forgot password handler to navigate to reset page
- `lib/features/authentication/presentation/pages/signup_page.dart` - Added forgot password link and handler
- `lib/features/authentication/presentation/pages/reset_password_confirm_page.dart` - Enhanced to extract URL parameters for deep linking
- `lib/features/authentication/presentation/pages/update_password_page.dart` - Added token extraction from URL parameters
- `lib/main.dart` - Updated MaterialApp.router configuration for deep linking support
- `test/integration_test/auth_flow_test.dart` - Created comprehensive integration tests for password reset flow

## Decisions Made
- Used GoRouter's built-in query parameter extraction rather than manual URL parsing
- Made password reset routes publicly accessible to support email-based deep linking
- Added helper methods in AppRouter for consistent URL parameter handling
- Documented URL schemes for both mobile (sage://) and web (https://) deep linking

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None - all tasks completed successfully without issues.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Password reset navigation is fully functional with deep linking support
- All authentication pages are properly connected with password reset links
- Router configuration supports both mobile and web deep linking scenarios
- Integration tests verify the complete password reset flow works correctly
- Ready for Phase 2: Household Creation with complete authentication foundation
