Question

Здравствуйте. Я пытаюсь войти в систему с правами администратора, и после выполнения всего, что я знаю, во время входа в систему я получаю сообщение об ошибке «Учетные данные не соответствуют нашим записям». Вот мой код. auth. php

        'web' => [
            'driver' => 'session',

        'admin' => [
            'driver' => 'session',

        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
    ],

            'driver' => 'eloquent',
            'model' => App\admin::class,
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],
