Usage

Include the HasOTPToken trait into your model

<?php
 
namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Jefte\OTPGenerator\Traits\HasOTPToken;

class User extends Authenticatable
{
  use HasFactory, Notifiable, HasOTPToken;
  
  
}

To Generate an OTP Token, use the createOtpToken method from the model

class HomeController extends Controller
{
   public function requestOtpToken(Request $request)
   {
      $user = $request->user();
      
      // Creating Token
      $token = $user->createOtpToken();
      
      
      // Accessing the created token
      $token->getGeneratedToken();
      
      // Sample Use Case
      $user->notify(new SendOtpNotification($token));
      
      
   }
   
   public function verifyOtpToken(Request $request)
   {
      
      $user = $request->user();
      
      // To Verify Token
      $token = $request->input('otp_token');
      
      if(! $user->verifyToken($myToken))
      {
          return response()->json([
              'message' => 'Invalid OTP'
          ], 422);
      }
      
   }
