@SouKBit per the docs, you need to adjust your auth.php like so:

'defaults' => [
    'guard' => 'api',
    'passwords' => 'users',
],

[alagoroVigo]

From the docs:

Multiple Guards
If the newly created 'api' guard is not set as a default guard 
or you have defined multiple guards to handle authentication, 
you should specify the guard when calling auth().

  $token = auth('api')->attempt($credentials);

Add "implements JWTSubject" in your user class.

class User extends Authenticatable implements JWTSubject

[webeleven-tbarbosa]

Solved for me, trying for this example:

'api' => [ 'driver' => 'jwt', 'provider' => 'users', ],

That line is the problem for the laravel 5.8 ^.

'hash' => false,

Method Illuminate\Auth\SessionGuard::factory does not exist.

If you confirm there are no wrong on your project to implement jwt that time you can do it...

php artisan config:cache
php artisan cache:clear
php artisan route:clear

.. it's work for me...

implements JWTSubject

and use Tymon\JWTAuth\Contracts\JWTSubject;

eg

...
use Tymon\JWTAuth\Contracts\JWTSubject;

class User extends Authenticatable implements JWTSubject
{
...
