Modify App\User.php file

<?php namespace App;
 use Laravel\Passport\HasApiTokens; 
use Illuminate\Notifications\Notifiable; 
use Illuminate\Foundation\Auth\User as Authenticatable; 

class User extends Authenticatable {    
 use HasApiTokens, Notifiable; 
}

Register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:

<?php namespace App\Providers; 
use Laravel\Passport\Passport;
 use Illuminate\Support\Facades\Gate;
 use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider; 

class AuthServiceProvider extends ServiceProvider {  
   /**      
    * The policy mappings for the application.      
    *     
    * @var array      
    */     
     protected $policies = [  
       'App\Model' => 'App\Policies\ModelPolicy',   
      ];    
 /**      
   * Register any authentication / authorization services.      
   *
   * @return void     
   */  
   public function boot()     
   {
      $this->registerPolicies();   
      Passport::routes();    
   } 
}

Configure config/auth.php

'guards' => [     
         'web' => [         
                   'driver' => 'session',
                   'provider' => 'users',
           ],
         'api' => [         
                   'driver' => 'passport',
                   'provider' => 'users',    
                ],
 ],

SET TO GO, now get access token to proceed

Use the generated key in initial step called Password grant client
