if( Auth::attempt(['mssv' => $username,'password' =>$password])) {
      $success = new MessageBag(['successlogin' => 'Login Success]);
      return redirect()->back()->withErrors($success);
}
elseif( Auth::guard('admins')->attempt(['manv' => $username,'password' =>$password])) {
      $success = new MessageBag(['successlogin' => 'Login Success]);
      return redirect()->back()->withErrors($success);
}
else {
      $errors = new MessageBag(['errorlogin' => 'Login Fail']);
      return redirect()->back()->withErrors($errors);
}

@guest
    <li class="nav-item">
        <a class="nav-link" href="#">Guest page</a>
      </li>
@endguest
