- Rate limiting on authentication endpoints

## Testing

Run the admin functionality test:
```bash
node test-admin-enhanced.js
```

This will test all admin features including:
- User creation and management
- Role updates
- Bulk operations
- Statistics tracking
- Search and filtering

## Technical Implementation

## Future Enhancements

### Potential Improvements

### Scalability Considerations
