Apply Auth Middleware To All Laravel Routes

What is the correct way to authenticate all routes except login and register when I apply auth middleware in all controllers? Is there a way to apply auth middleware in one place and exclude login, register routes?

you can apply middlewares in the routes.php file, what you need to do is to put all your routes on a group, and add the middleware 'auth' ( except the Auth::routes() which are already configured), for example :

Route::middleware(['first', 'second'])->group(function () {
    Route::get('/', function () {
        // Uses first & second Middleware
    });

    Route::get('user/profile', function () {
        // Uses first & second Middleware
    });
});
