### 2. Backend Components

#### Forms (`core/forms.py`)

**`UserSignupForm`** - Custom User Creation Form
- Extends Django's `UserCreationForm`
- Additional fields: email (required), first_name, last_name

### 3. Django Built-in Auth URLs

The project already includes Django's built-in authentication URLs via:
```python
path('accounts/', include('django.contrib.auth.urls'))
```

This provides the following URL patterns:
- `login/` - Login page
- `logout/` - Logout
- `password_change/` - Password change form
- `password_change/done/` - Password change success
- `password_reset/` - Password reset request

- `reset/<uidb64>/<token>/` - Password reset confirmation
- `reset/done/` - Password reset complete

### Security Features
- CSRF protection on all forms
- Password strength requirements displayed
- Password validators enforced (Django's built-in)

## Configuration Requirements

### Email Backend
Currently set to console backend for development:
```python
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
```

For production, configure SMTP settings in `settings.py`:
```python
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.example.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'your-email@example.com'
EMAIL_HOST_PASSWORD = 'your-password'
DEFAULT_FROM_EMAIL = 'noreply@agdarcentre.sa'
```

### Password Validators
Already configured in `settings.py`:
- UserAttributeSimilarityValidator
- MinimumLengthValidator (8 characters)
- CommonPasswordValidator
- NumericPasswordValidator

### Authentication Settings
Already configured:
```python
LOGIN_URL = 'login'
LOGIN_REDIRECT_URL = '/'
LOGOUT_REDIRECT_URL = 'login'
AUTH_USER_MODEL = 'core.User'
```

## URL Structure

### Public URLs (No Authentication Required)
- `/en/accounts/login/` - Login page
- `/en/signup/` - User registration
- `/en/accounts/password_reset/` - Request password reset
- `/en/accounts/password_reset/done/` - Reset email sent
- `/en/accounts/reset/<uidb64>/<token>/` - Reset password
- `/en/accounts/reset/done/` - Reset complete

### Protected URLs (Authentication Required)
- `/en/accounts/password_change/` - Change password
- `/en/accounts/password_change/done/` - Change complete

## Future Enhancements (Optional)

### Email Verification
- Add email confirmation step after signup
- Prevent login until email verified
- Resend verification email functionality

### Social Authentication
- Google OAuth integration
- Microsoft OAuth integration
- Apple Sign-In

### Two-Factor Authentication (2FA)
- SMS-based 2FA
- Authenticator app support (TOTP)
- Backup codes

### Password Strength Meter
- Visual password strength indicator
- Real-time feedback as user types
- Suggestions for stronger passwords

### Rate Limiting
- Prevent brute force attacks
- Limit password reset requests
- Account lockout after failed attempts

### Account Activation Workflow
- Admin approval for new accounts
- Role assignment during signup
- Tenant assignment logic

## Notes

1. **Tenant Assignment**: The current signup flow creates users without tenant assignment. You may need to add logic to:
   - Assign users to a default tenant
   - Allow tenant selection during signup
   - Require admin approval for tenant assignment

2. **Role Assignment**: New users are created without a specific role. Consider:
   - Default role assignment (e.g., FRONT_DESK)
   - Role selection during signup (if appropriate)
   - Admin role assignment workflow

3. **Auto-Login**: The SignupView has commented-out code for auto-login after signup. Uncomment if desired:
   ```python
   from django.contrib.auth import login
   login(self.request, self.object)
   return redirect('core:dashboard')
   ```

4. **Email Templates**: Consider creating HTML email templates for better presentation:
   - Create `password_reset_email.html` for HTML version
   - Use Django's `EmailMultiAlternatives` for both text and HTML

5. **Translations**: Run `python manage.py makemessages -l ar` to generate Arabic translation files for all new strings.

## Conclusion

This implementation provides a complete, production-ready user authentication system with all standard workflows. The templates are consistent with the existing Agdar design system, fully internationalized, and follow Django best practices.

All components are ready for immediate use in development and can be deployed to production after configuring the email backend and adding any desired optional enhancements.
