+# Customer Authentication Implementation
+
+**Date**: 2025-11-24
+**Status**: Completed
+
+## Overview
+
+This document describes the implementation of customer authentication for the shop frontend, including login, registration, and account management pages. This work creates a complete separation between customer authentication and admin/vendor authentication systems.
+
+## Problem Statement
+
+The shop frontend needed proper authentication pages (login, registration, forgot password) and a working customer authentication system. The initial implementation had several issues:
+
+1. No styled authentication pages for customers
+2. Customer authentication was incorrectly trying to use the User model (admins/vendors)
+3. Cookie paths were hardcoded and didn't work with multi-access routing (domain, subdomain, path-based)
+4. Vendor detection method was inconsistent between direct path access and API calls via referer
+
+## Solution Architecture
+
+### 1. Customer vs User Separation
+
+**Key Insight**: Customers are NOT users. They are a separate entity in the system.
+
+- **Users** (`models/database/user.py`): Admin and vendor accounts
+  - Have `role` field (admin/vendor)
+  - Have `username` field
+  - Managed via `app/services/auth_service.py`
+
+- **Customers** (`models/database/customer.py`): Shop customers
+  - Vendor-scoped (each vendor has independent customers)
+  - No `role` or `username` fields
+  - Have `customer_number`, `total_orders`, vendor relationship
+  - Managed via `app/services/customer_service.py`
+
+### 2. JWT Token Structure
+
+Customer tokens have a distinct structure:
+
+```python
+{
+    "sub": str(customer.id),           # Customer ID
+    "email": customer.email,
+    "vendor_id": vendor_id,            # Important: Vendor isolation
+    "type": "customer",                # CRITICAL: Distinguishes from User tokens
+    "exp": expire_timestamp,
+    "iat": issued_at_timestamp,
+}
+```
+
+User tokens have `type` implicitly set to user role (admin/vendor) and different payload structure.
+
+### 3. Cookie Path Management
+
+Cookies must be set with paths that match how the vendor is accessed:
+
+| Access Method | Example URL | Cookie Path |
+|--------------|-------------|-------------|
+| Domain | `wizamart.com/shop/account/login` | `/shop` |
+| Subdomain | `wizamart.localhost/shop/account/login` | `/shop` |
+| Path-based | `localhost/vendors/wizamart/shop/account/login` | `/vendors/wizamart/shop` |
+
+This ensures cookies are only sent to the correct vendor's routes.
+

+
+### Important Schema Change
+
+#### `models/schema/auth.py` - Unified Login Schema
+
+Changed the `UserLogin` schema to use `email_or_username` instead of `username` to support both username and email login across all contexts (admin, vendor, and customer).
+
+**Before**:
+```python
+class UserLogin(BaseModel):
+    username: str
+    password: str
+```
+
+**After**:
+```python
+class UserLogin(BaseModel):
+    email_or_username: str = Field(..., description="Username or email address")
+    password: str
+    vendor_code: Optional[str] = Field(None, description="Optional vendor code for context")
+```
+
+**Impact**: This change affects all login endpoints:
+- Admin login: `/api/v1/admin/auth/login`
+- Vendor login: `/api/v1/vendor/auth/login`
+- Customer login: `/api/v1/shop/auth/login`
+
+**Updated Files**:
+- `app/services/auth_service.py` - Changed `user_credentials.username` to `user_credentials.email_or_username`
+- `app/api/v1/admin/auth.py` - Updated logging to use `email_or_username`
+- `static/admin/js/login.js` - Send `email_or_username` in payload
+- `static/vendor/js/login.js` - Send `email_or_username` in payload
+
+### Files Modified
+
+#### 1. `app/api/v1/shop/auth.py`
+
+**Changes**:
+- Added `CustomerLoginResponse` model (uses `CustomerResponse` instead of `UserResponse`)
+- Updated `customer_login` endpoint to:
+  - Calculate cookie path dynamically based on vendor access method
+  - Set cookie with correct path for multi-access support
+  - Return `CustomerLoginResponse` with proper customer data
+- Updated `customer_logout` endpoint to calculate cookie path dynamically
+
+**Key Code**:
+```python
+# Calculate cookie path based on vendor access method
+vendor_context = getattr(request.state, 'vendor_context', None)
+access_method = vendor_context.get('detection_method', 'unknown') if vendor_context else 'unknown'
+
+cookie_path = "/shop"  # Default for domain/subdomain access
+if access_method == "path":
+    # For path-based access like /vendors/wizamart/shop
+    full_prefix = vendor_context.get('full_prefix', '/vendor/') if vendor_context else '/vendor/'
+    cookie_path = f"{full_prefix}{vendor.subdomain}/shop"
+
+response.set_cookie(
+    key="customer_token",
+    value=token,
+    httponly=True,
+    secure=should_use_secure_cookies(),
+    samesite="lax",
+    max_age=expires_in,
+    path=cookie_path,  # Dynamic path
+)
+```
+
+#### 2. `app/services/customer_service.py`
+
+**Changes**:
+- Updated `login_customer` to create JWT tokens directly using `auth_manager`
+- No longer tries to use `auth_service.create_access_token()` (that's for Users only)
+- Directly uses `jose.jwt.encode()` with custom customer payload
+
+**Key Code**:
+```python
+from jose import jwt
+from datetime import datetime, timedelta, timezone
+
+auth_manager = self.auth_service.auth_manager
+expires_delta = timedelta(minutes=auth_manager.token_expire_minutes)
+expire = datetime.now(timezone.utc) + expires_delta
+
+payload = {
+    "sub": str(customer.id),
+    "email": customer.email,
+    "vendor_id": vendor_id,
+    "type": "customer",  # Critical distinction
+    "exp": expire,
+    "iat": datetime.now(timezone.utc),
+}
+
+token = jwt.encode(payload, auth_manager.secret_key, algorithm=auth_manager.algorithm)
+```
+
+#### 3. `app/api/deps.py`
+
+**Major Rewrite**: `get_current_customer_from_cookie_or_header`
+
+**Before**: Tried to validate customer tokens as User tokens, expected `role` field
+
+**After**:
+- Decodes JWT manually
+- Validates `type == "customer"` in payload
+- Loads Customer from database (not User)
+- Returns Customer object
+
+**Key Code**:
+```python
+def get_current_customer_from_cookie_or_header(
+        request: Request,
+        credentials: Optional[HTTPAuthorizationCredentials] = Depends(security),
+        customer_token: Optional[str] = Cookie(None),
+        db: Session = Depends(get_db),
+):
+    from models.database.customer import Customer
+    from jose import jwt, JWTError
+
+    token, source = _get_token_from_request(...)
+
+    if not token:
+        raise InvalidTokenException("Customer authentication required")
+
+    # Decode and validate customer JWT token
+    payload = jwt.decode(token, auth_manager.secret_key, algorithms=[auth_manager.algorithm])
+
+    # Verify this is a customer token
+    if payload.get("type") != "customer":
+        raise InvalidTokenException("Customer authentication required")
+
+    customer_id = payload.get("sub")
+    customer = db.query(Customer).filter(Customer.id == int(customer_id)).first()
+
+    if not customer or not customer.is_active:
+        raise InvalidTokenException("Customer not found or inactive")
+
+    return customer  # Returns Customer, not User
+```
+
+#### 4. `app/routes/shop_pages.py`
+
+**Changes**:
+- Changed import from `User` to `Customer`
+- Updated all protected route handlers:
+  - Changed parameter type from `current_user: User` to `current_customer: Customer`
+  - Updated function calls from `user=current_user` to `user=current_customer`
+
+**Affected Routes**:
+- `/account/dashboard`
+- `/account/orders`
+- `/account/orders/{order_id}`
+- `/account/profile`
+- `/account/addresses`
+- `/account/wishlist`
+- `/account/reviews`
+
+#### 5. `middleware/vendor_context.py`
+
+**Critical Fix**: Harmonized vendor detection methods
+
+**Problem**:
+- Direct page access: `detection_method = "path"`
+- API call via referer: `detection_method = "referer_path"`
+- This inconsistency broke cookie path calculation
+
+**Solution**:
+When detecting vendor from referer path, use the same `detection_method = "path"` and include the same fields (`full_prefix`, `path_prefix`) as direct path detection.
+
+**Key Code**:
+```python
+# Method 1: Path-based detection from referer path
+if referer_path.startswith("/vendors/") or referer_path.startswith("/vendor/"):
+    prefix = "/vendors/" if referer_path.startswith("/vendors/") else "/vendor/"
+    path_parts = referer_path[len(prefix):].split("/")
+    if len(path_parts) >= 1 and path_parts[0]:
+        vendor_code = path_parts[0]
+        prefix_len = len(prefix)
+
+        # Use "path" as detection_method to be consistent with direct path detection
+        return {
+            "subdomain": vendor_code,
+            "detection_method": "path",  # Consistent!
+            "path_prefix": referer_path[:prefix_len + len(vendor_code)],
+            "full_prefix": prefix,
+            "host": referer_host,
+            "referer": referer,
+        }
+```
+
+#### 6. `app/exceptions/handler.py`
+
+**Changes**:
+- Password sanitization in validation error logging
+- Already had proper redirect logic for customer login (no changes needed)
+
+#### 7. `models/schema/auth.py`
+
+**Changes**:
+- Updated `UserLogin` schema to accept `email_or_username` instead of `username`
+- This allows customers to login with email (they don't have usernames)
+
+### Multi-Access Routing Support
+
+The implementation properly supports all three vendor access methods:
+
+#### Domain-based Access
+```
+URL: https://wizamart.com/shop/account/login
+Cookie Path: /shop
+Cookie Sent To: https://wizamart.com/shop/*
+```
+
+#### Subdomain-based Access
+```
+URL: https://wizamart.myplatform.com/shop/account/login
+Cookie Path: /shop
+Cookie Sent To: https://wizamart.myplatform.com/shop/*
+```
+
+#### Path-based Access
+```
+URL: https://myplatform.com/vendors/wizamart/shop/account/login
+Cookie Path: /vendors/wizamart/shop
+Cookie Sent To: https://myplatform.com/vendors/wizamart/shop/*
+```
+
+## Authentication Flow
+
+### Login Flow
+
+1. **User loads login page** → `GET /vendors/wizamart/shop/account/login`
+   - Middleware detects vendor from path
+   - Sets `detection_method = "path"` in vendor_context
+   - Renders login template
+
+2. **User submits credentials** → `POST /api/v1/shop/auth/login`
+   - Middleware detects vendor from Referer header
+   - Sets `detection_method = "path"` (harmonized!)
+   - Validates credentials via `customer_service.login_customer()`
+   - Creates JWT token with `type: "customer"`
+   - Calculates cookie path based on access method
+   - Sets `customer_token` cookie with correct path
+   - Returns token + customer data
+
+3. **Browser redirects to dashboard** → `GET /vendors/wizamart/shop/account/dashboard`
+   - Browser sends `customer_token` cookie (path matches!)
+   - Dependency `get_current_customer_from_cookie_or_header` extracts token
+   - Decodes JWT, validates `type == "customer"`
+   - Loads Customer from database
+   - Renders dashboard with customer data
+
+### Logout Flow
+
+1. **User clicks logout button** → Shows Tailwind modal confirmation
+   - Custom modal (not browser confirm dialog)
+   - Alpine.js state management
+   - Smooth animations with transitions
+   - Dark mode support
+
+2. **User confirms logout** → `POST /api/v1/shop/auth/logout`
+   - Calculates cookie path (same logic as login)
+   - Deletes cookie with matching path
+   - Returns success message
+
+3. **Frontend redirects to login page**
+   - Shows success toast notification
+   - Clears localStorage token
+   - Redirects after 500ms delay
+
+## Security Features
+
+### Cookie Security
+
+```python
+response.set_cookie(
+    key="customer_token",
+    value=token,
+    httponly=True,        # JavaScript cannot access (XSS protection)
+    secure=True,          # HTTPS only (production/staging)
+    samesite="lax",       # CSRF protection
+    max_age=1800,         # 30 minutes (matches JWT expiry)
+    path=cookie_path,     # Restricted to vendor's shop routes
+)
+```
+
+### Token Validation
+
+- JWT expiration checked
+- Customer active status verified
+- Token type validated (`type == "customer"`)
+- Vendor isolation enforced (customer must belong to vendor)
+
+### Password Security
+
+- Bcrypt hashing via `auth_manager.hash_password()`
+- Validation errors sanitized (passwords never logged)
+- Minimum password length enforced
+
+## Design Patterns Followed
+
+### Frontend Templates
+
+All authentication pages follow the shop template pattern:
+
+```jinja2
+{% extends "shop/base.html" %}
+
+{% block title %}Page Title{% endblock %}
+
+{% block alpine_data %}componentName(){% endblock %}
+
+{% block content %}
+<!-- Page content -->
+{% endblock %}
+
+{% block extra_scripts %}
+<script>
+function componentName() {
+    return {
+        ...shopLayoutData(),
+        // Component-specific data/methods
+    }
+}
+</script>
+{% endblock %}
+```
+
+**Benefits**:
+- Consistent header/footer/navigation
+- Theme CSS variables automatically injected
+- Dark mode support
+- Mobile responsive
+- Alpine.js component pattern
+
+### Service Layer
+
+- Customer operations in `customer_service.py`
+- Auth operations in `auth_service.py`
+- Clear separation of concerns
+- Database operations via SQLAlchemy ORM
+
+### Exception Handling
+
+- Custom exceptions for customer-specific errors
+- Consistent error responses (JSON for API, HTML for pages)
+- Automatic redirect to login on 401 for HTML page requests
+
+### UI Components
+
+#### Logout Confirmation Modal
+
+Custom Tailwind CSS modal for logout confirmation instead of browser's native `confirm()` dialog.
+
+**Features**:
+- Beautiful animated modal with backdrop overlay
+- Warning icon (red triangle with exclamation mark)
+- Clear confirmation message
+- Two action buttons: "Logout" (red) and "Cancel" (gray)
+- Dark mode support
+- Mobile responsive
+- Keyboard accessible (ARIA attributes)
+- Click backdrop to dismiss
+
+**Implementation**:
+```html
+<!-- Modal trigger -->
+<button @click="showLogoutModal = true">Logout</button>
+
+<!-- Modal component -->
+<div x-show="showLogoutModal" x-cloak class="fixed inset-0 z-50">
+    <!-- Backdrop with fade animation -->
+    <div x-show="showLogoutModal"
+         x-transition:enter="ease-out duration-300"
+         x-transition:enter-start="opacity-0"
+         x-transition:enter-end="opacity-100"
+         @click="showLogoutModal = false"
+         class="fixed inset-0 bg-gray-500 bg-opacity-75">
+    </div>
+
+    <!-- Modal panel with slide+scale animation -->
+    <div x-show="showLogoutModal"
+         x-transition:enter="ease-out duration-300"
+         x-transition:enter-start="opacity-0 scale-95"
+         x-transition:enter-end="opacity-100 scale-100"
+         class="bg-white dark:bg-gray-800 rounded-lg">
+        <!-- Modal content -->
+    </div>
+</div>
+```
+
+**Alpine.js Component**:
+```javascript
+function accountDashboard() {
+    return {
+        ...shopLayoutData(),
+        showLogoutModal: false,  // Modal state
+
+        confirmLogout() {
+            this.showLogoutModal = false;
+            // Perform logout API call
+            // Show toast notification
+            // Redirect to login
+        }
+    }
+}
+```
+
+**Why Custom Modal vs Browser Confirm**:
+- ✅ Consistent with design system
+- ✅ Customizable styling and animations
+- ✅ Dark mode support
+- ✅ Better mobile experience
+- ✅ More professional appearance
+- ✅ Accessible (ARIA labels, keyboard navigation)
+- ❌ Browser confirm: Cannot be styled, looks dated, poor mobile UX

+## Known Limitations
+
+1. **Password Reset Not Implemented**: `forgot-password` and `reset-password` endpoints are placeholders (TODO comments in code)
+
+2. **Email Verification Not Implemented**: Customers are immediately active after registration
+
+3. **Session Management**: No refresh tokens, single JWT with 30-minute expiry
+
+4. **Account Pages Are Placeholders**:
+   - `/account/orders` - needs order history implementation
+   - `/account/profile` - needs profile editing implementation
+   - `/account/addresses` - needs address management implementation
+
+## Future Enhancements
+
+1. **Password Reset Flow**:
+   - Generate secure reset tokens
+   - Send password reset emails
+   - Token expiry and validation
+   - Password reset form
+
+2. **Email Verification**:
+   - Send verification email on registration
+   - Verification token validation
+   - Resend verification email
+
+3. **Account Management**:
+   - Edit profile (name, email, phone)
+   - Change password
+   - Manage addresses (CRUD)
+   - View order history with filtering/search
+   - Order tracking
+
+4. **Security Enhancements**:
+   - Refresh tokens for longer sessions
+   - Rate limiting on login/registration
+   - Account lockout after failed attempts
+   - 2FA/MFA support
+
+5. **User Experience**:
+   - Remember me functionality
+   - Social login (OAuth)
+   - Progressive disclosure of forms
+   - Better error messages

+## Deployment Notes
+
+### Environment Variables
+
+No new environment variables required. Uses existing:
+- `JWT_SECRET_KEY` - for token signing
+- `JWT_EXPIRE_MINUTES` - token expiry (default: 30)
+- `ENVIRONMENT` - for secure cookie setting
+
+### Database
+
+No migrations required. Uses existing `customer` table.
+
+### Static Files
+
+Ensure these files exist:
+- `static/shared/js/log-config.js`
+- `static/shared/js/icons.js`
+- `static/shop/js/shop-layout.js`
+- `static/shared/js/utils.js`
+- `static/shared/js/api-client.js`
+- `static/shop/css/shop.css`
+
+## Troubleshooting
+
+### Issue: "No token for path"
+
+**Cause**: Cookie path doesn't match request path
+
+**Solution**:
+- Check vendor context middleware is running
+- Verify `detection_method` is set correctly
+- Confirm cookie path calculation includes vendor subdomain for path-based access
+
+### Issue: "Invalid token type"
+
+**Cause**: Trying to use User token for customer route or vice versa
+
+**Solution**:
+- Ensure customer login creates token with `type: "customer"`
+- Verify dependency checks `type == "customer"`
+
+### Issue: Cookie not sent by browser
+
+**Cause**: Cookie path doesn't match or cookie expired
+
+**Solution**:
+- Check browser DevTools → Application → Cookies
+- Verify cookie path matches request URL
+- Check cookie expiry timestamp
+
+## Summary
+
+This implementation establishes a complete customer authentication system that is:
+
+✅ **Secure**: HTTP-only cookies, CSRF protection, password hashing
+✅ **Scalable**: Multi-tenant with vendor isolation
+✅ **Flexible**: Supports domain, subdomain, and path-based access
+✅ **Maintainable**: Clear separation of concerns, follows established patterns
+✅ **User-Friendly**: Responsive design, theme integration, proper UX flows
+
+The key architectural decision was recognizing that customers and users are fundamentally different entities requiring separate authentication flows, token structures, and database models.

+## Key Files
+
+### Created
+- `app/templates/shop/account/login.html`
+- `app/templates/shop/account/register.html`
+- `app/templates/shop/account/forgot-password.html`
+- `app/templates/shop/account/dashboard.html`
+
+### Modified
+- `app/api/v1/shop/auth.py` - Dynamic cookie paths
+- `app/api/deps.py` - Customer authentication dependency
+- `app/services/customer_service.py` - Direct JWT token creation
+- `app/routes/shop_pages.py` - Customer type hints
+- `middleware/vendor_context.py` - Harmonized detection methods
+
+## Critical Architecture Decision
+
+**Customers ≠ Users**
+
+- **Users** (admin/vendor): Have `role`, `username`, managed by `auth_service`
+- **Customers**: Vendor-scoped, have `customer_number`, managed by `customer_service`
+
+JWT tokens have `type: "customer"` to distinguish them.
+
+## Cookie Path Logic
+
+```python
+# Domain/Subdomain access
+cookie_path = "/shop"
+
+# Path-based access (/vendors/wizamart/shop)
+cookie_path = f"/vendors/{vendor_code}/shop"
+```
+
+## Authentication Flow
+
+1. Login → Create JWT with `type: "customer"`
+2. Set cookie with vendor-aware path
+3. Dashboard request → Cookie sent (path matches!)
+4. Dependency decodes JWT, validates type, loads Customer
+5. Render dashboard with customer data
+
+## Logout Flow
+
+1. User clicks "Logout" button → Custom Tailwind modal appears
+2. User confirms → API call to `/api/v1/shop/auth/logout`
+3. Cookie deleted, localStorage cleared
+4. Success toast shown, redirect to login page
+
+**Note**: Uses custom modal instead of browser's `confirm()` for better UX and styling consistency.
+
+## Testing URLs
+
+```
+# Path-based access
+http://localhost:8000/vendors/wizamart/shop/account/login
+http://localhost:8000/vendors/wizamart/shop/account/register
+http://localhost:8000/vendors/wizamart/shop/account/dashboard
+```

+
+## 🎨 Theme Integration
+
+All authentication pages inject the vendor's theme CSS variables for consistent branding:
+
+```html
+<style id="vendor-theme-variables">
+    :root {
+        {% for key, value in theme.css_variables.items() %}
+        {{ key }}: {{ value }};
+        {% endfor %}
+    }
+
+    /* Theme-aware button and focus colors */
+    .btn-primary-theme {
+        background-color: var(--color-primary);
+    }
+    .btn-primary-theme:hover:not(:disabled) {
+        background-color: var(--color-primary-dark, var(--color-primary));
+        filter: brightness(0.9);
+    }
+    .focus-primary:focus {
+        border-color: var(--color-primary);
+        box-shadow: 0 0 0 3px rgba(var(--color-primary-rgb, 124, 58, 237), 0.1);
+    }
+</style>
+```
+
+### Themed Elements
+
+| Element | CSS Variable | Usage |
+|---------|-------------|--------|
+| Left panel background | `var(--color-primary)` | Brand color fills entire left column |
+| Submit buttons | `var(--color-primary)` | Primary action buttons |
+| Links | `var(--color-primary)` | Forgot password, register, login links |
+| Checkboxes | `var(--color-primary)` | Remember me, marketing consent |
+| Focus states | `var(--color-primary)` | Input field focus rings |
+| Vendor logo | `theme.branding.logo` | Displayed in left column |
+
+### Benefits
+- ✅ Each vendor's auth pages automatically match their brand
+- ✅ Consistent with main shop design
+- ✅ Dark mode adapts to vendor colors
+- ✅ Professional, polished appearance
+- ✅ No custom CSS needed per vendor

+## 🔗 Navigation Flow
+
+```
+Shop Homepage
+    ↓
+Login Page ←→ Register Page
+    ↓              ↓
+Forgot Password    |
+    ↓              ↓
+Check Email   Account/Cart
+```
+
+### Link Structure
+- **Login Page:**
+  - "Forgot password?" → `/shop/account/forgot-password`
+  - "Create an account" → `/shop/account/register`
+  - "← Continue shopping" → `/shop/`
+
+- **Register Page:**
+  - "Already have an account? Sign in instead" → `/shop/account/login`
+
+- **Forgot Password Page:**
+  - "Remember your password? Sign in" → `/shop/account/login`
+  - "← Continue shopping" → `/shop/`
+
+All links use `{{ base_url }}` for multi-access routing support.
+

+
+## 🛠️ Customization Guide
+
+### For Developers
+
+#### Adding New Fields
+1. Add field to HTML form
+2. Add field to Alpine.js data
+3. Update validation logic
+4. Update API request body
+5. Update backend endpoint
+
+#### Changing Validation Rules
+Edit the `validateForm()` method in Alpine.js component:
+
+```javascript
+validateForm() {
+    this.clearAllErrors();
+    let isValid = true;
+
+    // Add/modify validation rules
+    if (!this.formData.field_name.trim()) {
+        this.errors.field_name = 'Field is required';
+        isValid = false;
+    }
+
+    return isValid;
+}
+```
+
+#### Customizing Theme Variables
+Vendors can customize colors in their theme configuration:
+
+```python
+theme = {
+    "colors": {
+        "primary": "#6366f1",  # Changes all primary elements
+        "secondary": "#8b5cf6",
+        "accent": "#ec4899"
+    }
+}
+```
+
+### For Vendors
+Vendors can customize:
+- Primary brand color (buttons, links, left panel)
+- Logo (displayed in left column)
+- Custom CSS (additional styling)
+- Dark mode logo variant
+
+No code changes needed - all controlled via theme configuration.
