authentication - Laravel 5.2 Auth::login($user) not working -

i writing laravel 5.2 application. need manually login user using \auth::login($user). doing in following way.

  if ($user = user::where('phone',session('phone'))->first())   {         \auth::login($user);          //   \auth::loginusingid($user->id);         //  auth::attempt(['email' => $user->email, 'password' => 'password']);          $data = \auth::user();  //returning correct results   }  

i have tried options namely auth::login($user), authh:loginusingid($user->id) , attempt method. these methods working fine $data variable storing object of correct user. problem when move other route '/home' user remain no more authenticated.

what might wrong here? how correctly?

since laravel 5.2, have attach routes need session the 'web' middleware. see app/http/kernel.php, 'web' middleware contains \illuminate\session\middleware\startsession.
