- Table renamed to `otp_tokens`
- Added `user_id` field as unsignedInteger, nullable
- Added index on `user_id` for faster queries
- Changed index strategy for better query performance

### 4. Updated Bootstrap (`bootstrap.php`)
- **Added imports**: 
  - `App\Models\User`
  - `App\Models\Otp`
  - `App\Services\OtpService`
  - `App\Services\TwoFactorService`

- **Registered Model Services as Singletons**:
  ```php
  $app->singleton(User::class, function (App $app) {
      return new User($app->resolve(Database::class));
  });

  $app->singleton(Otp::class, function (App $app) {
      return new Otp($app->resolve(Database::class));
  });
  ```

- **Registered Business Logic Services**:
  ```php
  $app->singleton(OtpService::class, function (App $app) {
      return new OtpService(
          $app->resolve(Otp::class),
          $app->resolve(Logger::class),
          $app->resolve(RateLimiter::class),
          $app->resolve(CacheInterface::class)
      );
  });

  $app->singleton(TwoFactorService::class, function (App $app) {
      return new TwoFactorService(
          new \App\Models\UserTwoFactor($app->resolve(Database::class)),
          $app->resolve(OtpService::class),
          $app->resolve(Logger::class)
      );
  });
  ```

## Usage

### In Controllers or Services:

```php
// Get OtpService from container
$otpService = $app->resolve(OtpService::class);

// Get User model from container
$userModel = $app->resolve(User::class);
$user = $userModel->findByEmail('user@example.com');

// Get Otp model from container
$otpModel = $app->resolve(Otp::class);
$activeOtp = $otpModel->findActive('user@example.com', 'authentication');

// From an OTP instance, get its associated user
$user = $otp->user();
```

## Migration Notes

If you've already run migrations before these changes:

```bash
# Reset and run fresh
php artisan migrate:reset
php artisan migrate

# Or just refresh
php artisan migrate:refresh
```

## What's Next

The system is now fully integrated:
- ✅ User model available
- ✅ OTP model references users via user_id
- ✅ All services registered in container
- ✅ Ready for authentication flows
