Laravel 5: How to store extra attributes to user login session

Question

I'm actually implementing 2-factor auth into the project. What I did was

Auth::user()->google2fa_passed = 1;

In fact it doesn't really store, when navigate to another page, the value is missing.

I also don't want to keep in another session, because when user logout (or users remove the session cookie from their browser), then will show a login page, and go through the 2 factor auth again.

Any idea how to save 1 more attribute to user session?

Eventually, I use session to store.

After key in the 6-digits code, store a flag into session

\Session::put('totp_passed', 1);

In app/Http/Middleware/Authenticate.php, remove the 2FA session if session expired

public function handle($request, Closure $next)
{   
    if ($this->auth->guest()) {
        // remove the 2-factor auth if the user session expired
        \Session::forget('totp_passed'); // <------- add this line

        if ($request->ajax()) {
            return response('Unauthorized.', 401);
        } else {
            return redirect()->route('auth.login');
        }   
    }
    return $next($request);
}

Then create another middleware, e.g. app/Http/Middleware/TwoFactorAuth.php

namespace App\Http\Middleware;

use Closure;

class TwoFactorAuth
{
    /** 
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {   
        if (!\Session::has('totp_passed')) {
            return redirect()->route('auth.2fa');
        }   

        return $next($request);
    }   
}

In app/Http/Kernel.php

protected $routeMiddleware = [ 
    'auth'       => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest'      => \App\Http\Middleware\RedirectIfAuthenticated::class,
    '2fa'        => \App\Http\Middleware\TwoFactorAuth::class, // <------ add this line
];

How to use

Route::group(['middleware' => 'auth'], function () {
    // must be login first only can access this page
    Route::get('2fa', ['as' => 'auth.2fa', 'uses' => 'Auth\AuthController@get2FactorAuthentication']);
    Route::post('2fa', ['uses' => 'Auth\AuthController@post2FactorAuthentication']);

    // add 2-factor auth middleware
    Route::group(['middleware' => '2fa'], function () {
        // all routes that required login
    }); 
});
