Laravel Passport use Different Model
<p>I want to add a custom guard to Laravel that uses Passport but with different model (not User), but when I try to set the user for this guard  it is not working.</p>

<p>config/auth.php:</p>

<pre><code>&lt;?php

return [

/*
|--------------------------------------------------------------------------
| Authentication Defaults
|--------------------------------------------------------------------------
|
| This option controls the default authentication "guard" and password
| reset options for your application. You may change these defaults
| as required, but they're a perfect start for most applications.
|
*/

'defaults' =&gt; [
    'guard' =&gt; 'web',
    'passwords' =&gt; 'users',
],

/*
|--------------------------------------------------------------------------
| Authentication Guards
|--------------------------------------------------------------------------
|
| Next, you may define every authentication guard for your application.
| Of course, a great default configuration has been defined for you
| here which uses session storage and the Eloquent user provider.
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| Supported: "session", "token"
|
*/

'guards' =&gt; [
    'web' =&gt; [
        'driver' =&gt; 'session',
        'provider' =&gt; 'users',
    ],

    'api' =&gt; [
        'driver' =&gt; 'passport',
        'provider' =&gt; 'users',
    ],

    'conference' =&gt; [
        'driver' =&gt; 'passport',
        'provider' =&gt; 'participants',
    ],
],

| mechanisms used by this application to persist your user's data.
|
| If you have multiple user tables or models you may configure multiple
| sources which represent each model / table. These sources may then
| be assigned to any extra authentication guards you have defined.
|
| Supported: "database", "eloquent"

'providers' =&gt; [
    'users' =&gt; [
        'driver' =&gt; 'eloquent',
        'model' =&gt; App\Models\User::class,

    'participants' =&gt; [

| Resetting Passwords
|--------------------------------------------------------------------------
|
| Here you may set the options for resetting passwords including the view
| that is your password reset e-mail. You may also set the name of the
| table that maintains all of the reset tokens for your application.
|
| You may specify multiple password reset configurations if you have more
| than one user table or model in the application and you want to have
| separate password reset settings based on the specific user types.
|
| The expire time is the number of minutes that the reset token should be
| considered valid. This security feature keeps tokens short-lived so
| they have less time to be guessed. You may change this as needed.

'passwords' =&gt; [
    'users' =&gt; [
        'provider' =&gt; 'users',
        'email' =&gt; 'spark::auth.emails.password',
        'table' =&gt; 'password_resets',
        'expire' =&gt; 60,
    ],
],

];
</code></pre>

<p>in the controller I am setting the user for the custom guard:</p>

<pre><code>    auth()-&gt;guard('conference')-&gt;setUser($participant);
</code></pre>

<p>api.php:</p>

<pre><code>Route::group(['prefix' =&gt; '{activity}', 'middleware' =&gt; ['auth:conference', 'api']], function () { //

    Route::group(['prefix' =&gt; 'participant/{participant}'], function () {
        Route::any('join', 'API\ConferenceController@join');

    });
});
</code></pre>

<p>Participant model:</p>

<pre><code>use Laravel\Passport\HasApiTokens;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Participant extends Authenticatable
{
    use Enums, SoftDeletes, RequiresUUID, HasApiTokens, Notifiable;
</code></pre>

<p>but I can't access the route I get 401. When I change the provider for the 'conference' guard to be 'users' it works without problem.</p>

<p>What I am missing?</p>
