Two or more VerificationController for email

Hi, anyone know how send email verify depends on the user, i have three type of user, student, teacher, and user->like visitor, of course i've add two guards and providers to auth.php. Now when i try to register i watch if i change the VerificationController:

$this->middleware('auth');
$this->middleware('signed')->only('verify');
$this->middleware('throttle:6,1')->only('verify', 'resend');

like:

$this->middleware('auth:student');   //It's fine, works good. but if i write one by one
$this->middleware('signed')->only('verify');
$this->middleware('throttle:6,1')->only('verify', 'resend');

but when i write, something like this:

$this->middleware('auth','auth:student', 'auth:teacher');  //failed
$this->middleware('signed')->only('verify');
$this->middleware('throttle:6,1')->only('verify', 'resend');

$this->middleware('auth'); //falied
$this->middleware('auth:student'); //failed
$this->middleware('auth:teacher'); //failed
$this->middleware('signed')->only('verify');
$this->middleware('throttle:6,1')->only('verify', 'resend');

or

$this->middleware(['auth', 'auth:student','auth:teacher']); //failed

but, it doesn't work. Help.

Regards.
