How to disable Laravel eloquent Auto Increment?

if you wish to use a non-incrementing or a non-numeric primary key you must set the public $incrementing property on your model to false.

eg :

class UserVerification extends Model
{
    protected $primaryKey = 'your_key_name'; // or null

    public $incrementing = false;
}

in case of migration :

$table->integer('id')->unsigned(); // to remove primary key 
$table->primary('id'); //to add primary key

refer : https://laravel.com/docs/5.3/eloquent#eloquent-model-conventions

Try public $incrementing = false;
