php - Laravel Passport Multiauth -

i working on api 2 frontend apps (vue2/mobile). 1 uses user model , other uses admin model (laravel api)

i using laravel passport authenticating users , admins, provided access token users i'm facing problem admins

so did

1-> created admin model

<?php  namespace app;  use laravel\passport\hasapitokens; use illuminate\notifications\notifiable; use illuminate\foundation\auth\user authenticatable;  class admin extends authenticatable {     use hasapitokens, notifiable;      /**      * attributes mass assignable.      *      * @var array      */     protected $fillable = [         'name', 'email', 'password','role',     ];      /**      * attributes should hidden arrays.      *      * @var array      */     protected $hidden = [         'password', 'remember_token',     ]; } 

2-> created admins guard uses passport

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

3-> created route , controller granting access token admins

route::post('/oauth/token/admin', [     'uses' => 'auth\customaccesstokencontroller@issueusertoken' ]);  <?php  namespace app\http\controllers\auth;  use illuminate\http\request; use psr\http\message\serverrequestinterface; use laravel\passport\http\controllers\accesstokencontroller;  class customaccesstokencontroller extends accesstokencontroller {     /**      * hooks in before accesstokencontroller issues token      *      *      * @param  serverrequestinterface $request      * @return mixed      */     public function issueusertoken(serverrequestinterface $request)     {         $httprequest = request();          if ($httprequest->grant_type == 'password') {              $admin = \app\admin::where('email', $httprequest->username)                                ->where('password', $httprequest->password)                                ->first();             //dd($admin);              return $this->issuetoken($request);         }     } } 

4-> tested postman

http://localhost:8000/api/oauth/token/admin  client_id:4 client_secret:m4qklqhpkj4pgl52429ripassq3bojktjze3uowk grant_type:password username:admin@gmail.com password:secret  //i'm getting {   "error": "invalid_credentials",   "message": "the user credentials incorrect." }  //if use user model credentials  username:user@gmail.com password:secret  //i'm getting access token  {   "token_type": "bearer",   "expires_in": 31536000,   "access_token": "eyj0exaioijkv1qi....",   "refresh_token": "ui354efjlvdmoho...." }
