My web.php

<?php

| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!

*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('verifyotp', function () {
    return view('verifyotp');
});


Route::post('/verifyotp','verifyotpcontroller@verify'); 
Route::post('/resendotp','verifyotpcontroller@resendotp');  
Auth::routes();

 

Route::group(['middleware'=>'verifyotp'],function(){
Route::get('/home', 'HomeController@index')->name('home');

});

my login controller

<?php

namespace App\Http\Controllers\Auth;

    {
        
     $result= $this->guard()->attempt(
        $this->credentials($request), $request->filled('remember')
    );
     if ($result && auth()->user()->verifyotp==0) {
