+# Instructions 
+Here are special rules you must follow:
+1. All forms should use regular form url encoding.
+2. All routes should return html.
+3. Use htmx for all dynamic content, when possible.
+4. Use alpinejs for other dynamic content. For example, hiding or showing an element.
+5. Prefer using daisyui over raw tailwind where possible.
+6. Prefer using alpinejs over raw javascript. Raw javascript should almost never be needed.
+7. Always print unhandled exceptions to the console.
+8. Follow best practices for jinja template partials. That is, separate out components where appropriate.
+9. Ask the user when there is something unclear.
+10. I always run the server locally on port 5000, so you can use curl to test. No need to start it yourself.
+11. Design docs go into docs/design/*.md. These docs are always kept up to date.
+12. Before completing work, ensure that no design docs are left out of sync
+13. Plans go into docs/plans/*.md. These may not be kept in sync, as they are just for brainstorming.
+
+# Conventions
+1. modals are rendered server-side, by targeting #modal-holder, and using an hx-trigger response attribute for open-modal.
+2. modals are closed by adding the close-modal hx-trigger response attribute.
+3. modals can be closed by triggering a close-modal event anywhere in the dom.
+4. validation is done server-side. On modals, an error should cause the button to shake, and the invalid fields to be highlighted in red using normal daisyui paradigms. When relevant, there should be a notification banner inside the dialog-box to show the details of the error.
+5. When validation is done outside of a modal, it should cause a notification banner with the details.
+6. Testing is done with pytest.
+7. Testing is done with beautifulsoup4

+# Authentication System Implementation Plan
+
+## Current State Analysis
+
+The application is a Flask-based email organizer with the following current state:
+
+- **Models**: [`User`](app/models.py:10) and [`Folder`](app/models.py:18) models exist, but User model only has `id`, `email`, `password_hash`, and `imap_config` fields
+- **Routes**: Currently uses a hardcoded [`MOCK_USER_ID`](app/routes.py:10) for all operations
+- **UI**: Shows "User Name" as a placeholder in the top-right corner
+- **Authentication**: No authentication system currently implemented
+- **Tests**: Basic tests exist but don't account for authentication
+
+## Authentication System Architecture
+
+### System Overview
+
+```mermaid
+graph TD
+    A[User Request] --> B{Authenticated?}
+    B -->|No| C[Redirect to Login]
+    B -->|Yes| D[Process Request]
+    C --> E[Login Page]
+    F[New User] --> G[Signup Page]
+    G --> H[Create User]
+    H --> I[Login]
+    I --> D
+    E --> J[Validate Credentials]
+    J -->|Valid| K[Create Session]
+    K --> D
+    J -->|Invalid| E
+```
+
+### Key Components
+
+1. **Authentication Blueprint**: Separate blueprint for auth routes
+2. **Session Management**: Flask-Login for session handling
+3. **Password Hashing**: Werkzeug security utilities
+4. **Route Protection**: Decorators for requiring authentication
+5. **User Context**: Current user available in all templates
+
+### Database Schema Updates
+
+The [`User`](app/models.py:10) model needs the following changes:
+
+```python
+class User(Base):
+    __tablename__ = 'users'
+    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
+    first_name = db.Column(db.String(255), nullable=False)
+    last_name = db.Column(db.String(255), nullable=False)
+    email = db.Column(db.String(255), unique=True, nullable=False)
+    password_hash = db.Column(db.LargeBinary, nullable=False)
+    imap_config = db.Column(db.JSON)
+    created_at = db.Column(db.DateTime, default=datetime.utcnow)
+    updated_at = db.Column(db.DateTime, default=datetime.utcnow, onupdate=datetime.utcnow)
+```
+
+### Authentication Flow
+
+```mermaid
+sequenceDiagram
+    participant U as User
+    participant L as Login Page
+    participant S as Server
+    participant DB as Database
+    
+    U->>L: Navigate to /login
+    L->>U: Show login form
+    U->>S: POST /login with credentials
+    S->>DB: Query user by email
+    DB-->>S: Return user if found
+    S->>S: Verify password hash
+    S->>S: Create user session
+    S-->>U: Redirect to / with session cookie
+```
+
+## Implementation Plan
+
+### Phase 1: Core Authentication Infrastructure
+
+1. **Update Dependencies** ([`requirements.txt`](requirements.txt:1))
+   - Add Flask-Login for session management
+   - Add Werkzeug for password hashing (already included with Flask)
+
+2. **Update User Model** ([`app/models.py`](app/models.py:10))
+   - Add `first_name` and `last_name` fields
+   - Add `created_at` and `updated_at` timestamps
+   - Add password hashing methods
+   - Implement `__repr__` method for better debugging
+
+3. **Create Authentication Blueprint** ([`app/auth.py`](app/auth.py:1))
+   - Login route (`/login`)
+   - Signup route (`/signup`)
+   - Logout route (`/logout`)
+   - Authentication utilities
+
+4. **Update Application Factory** ([`app/__init__.py`](app/__init__.py:9))
+   - Initialize Flask-Login
+   - Register authentication blueprint
+   - Configure user loader callback
+
+### Phase 2: User Interface
+
+1. **Create Login Template** ([`app/templates/auth/login.html`](app/templates/auth/login.html:1))
+   - Email and password fields
+   - Remember me checkbox
+   - Links to signup and password reset
+   - Error message display
+
+2. **Create Signup Template** ([`app/templates/auth/signup.html`](app/templates/auth/signup.html:1))
+   - First name, last name, email, password fields
+   - Password confirmation field
+   - Terms of service checkbox
+   - Error message display
+
+3. **Update Main Layout** ([`app/templates/base.html`](app/templates/base.html:1))
+   - Conditional authentication links
+   - User display in top-right corner
+   - Flash message support
+
+4. **Update Index Template** ([`app/templates/index.html`](app/templates/index.html:1))
+   - Show actual user name instead of "User Name"
+   - Update logout functionality
+   - Add user dropdown menu
+
+### Phase 3: Route Protection and Integration
+
+1. **Create Authentication Middleware** ([`app/auth.py`](app/auth.py:1))
+   - `@login_required` decorator
+   - Anonymous user handling
+   - Session validation
+
+2. **Update Main Routes** ([`app/routes.py`](app/routes.py:1))
+   - Replace `MOCK_USER_ID` with authenticated user
+   - Add user context to all routes
+   - Update folder operations to use real user
+
+3. **Create Database Migration** ([`migrations/`](migrations/:1))
+   - Generate migration for User model changes
+   - Apply migration to database
+
+### Phase 4: Testing
+
+1. **Update Test Configuration** ([`tests/conftest.py`](tests/conftest.py:1))
+   - Add authentication fixtures
+   - Create test users with hashed passwords
+   - Session management for tests
+
+2. **Create Authentication Tests** ([`tests/test_auth.py`](tests/test_auth.py:1))
+   - User registration tests
+   - Login/logout tests
+   - Password validation tests
+   - Session management tests
+
+3. **Update Existing Tests** ([`tests/test_routes.py`](tests/test_routes.py:1))
+   - Add authentication requirements
+   - Update to use authenticated test users
+   - Test route protection
+
+### Phase 5: Security and Error Handling
+
+1. **Password Security** ([`app/auth.py`](app/auth.py:1))
+   - Password strength validation
+   - Secure password hashing
+   - Password reset functionality (future)
+
+2. **Error Handling** ([`app/errors.py`](app/errors.py:1))
+   - Authentication error handlers
+   - Validation error responses
+   - Security-related error logging
+
+3. **Session Security** ([`app/__init__.py`](app/__init__.py:1))
+   - Secure session configuration
+   - CSRF protection
+   - Session timeout handling

+
+## Acceptance Criteria
+
+1. **User Registration**: Users can create accounts with first name, last name, email, and password
+2. **User Login**: Users can log in using email and password
+3. **Session Management**: Users remain logged across requests
+4. **Route Protection**: Only authenticated users can access the main application
+5. **User Display**: User's name is displayed in the top-right corner
+6. **Logout**: Users can log out and clear their session
+7. **Password Security**: Passwords are properly hashed and verified
+8. **Test Coverage**: All authentication flows are tested
+9. **Integration**: Existing functionality works with authenticated users
+
+## Implementation Dependencies
+
+- Flask-Login: Session management
+- Werkzeug: Password hashing utilities
+- Flask-WTF: Form validation (optional but recommended)
+- pytest: Testing framework
+
+## Risk Assessment
+
+**Low Risk Items:**
+- Basic authentication implementation
+- Template updates for user display
+- Test updates for authenticated users
+
+**Medium Risk Items:**
+- Database migration for existing data
+- Session management configuration
+- Route protection integration
+
+**High Risk Items:**
+- Password security implementation
+- Session security configuration
+- Cross-site scripting protection
+
+## Success Metrics
+
+1. **Functional**: All authentication features work as specified
+2. **Security**: Passwords are properly hashed and sessions are secure
+3. **Performance**: Authentication adds minimal overhead to application
+4. **Maintainability**: Code is well-structured and easy to extend
+5. **Test Coverage**: 90%+ test coverage for authentication features
+
+## Requirements Fulfillment
+
+This plan addresses all the specified requirements:
+
+1. ✅ **A user can only view the current app if they are logged in**
+   - Route protection middleware ensures only authenticated users can access the main application
+
+2. ✅ **The user's name is shown in the top right instead of the temporary name that is visible**
+   - User templates will display `{{ current_user.first_name }} {{ current_user.last_name }}` instead of "User Name"
+
+3. ✅ **A user can logout**
+   - Logout route will clear the session and redirect to login page
+
+4. ✅ **Only the following are required to create an account: first name, last name, email, password**
+   - Signup form will collect exactly these four fields with proper validation
+
+5. ✅ **The password should be hashed when it's stored**
+   - Werkzeug's `generate_password_hash` and `check_password_hash` will be used for secure password handling
+
+6. ✅ **A user can log back in using their email and password**
+   - Login form will accept email and password, with proper verification against the hashed password
+
+7. ✅ **Tests are updated to be signed in as a user**
+   - Test fixtures will create authenticated users for all existing tests
+
+8. ✅ **Tests are updated to test creating a user**
+   - New test suite will cover user registration, login, and session management
+
+This plan provides a comprehensive approach to implementing authentication in the email organizer application while maintaining the existing functionality and ensuring security best practices.
