[FIXED] How to Prevent Multiple Login Of Same Credentials in Laravel 8?

Issue

I have a Laravel web app where multiple users login but I need to prevent login if the user has already logged.

I know that Laravel has a method (logoutOtherDevices) to logout the user when a second user (same credentials) is login.

Uncommented \Illuminate\Session\Middleware\AuthenticateSession::class, in app/Http/Kernel.php.

But I have doubt below mentioned code where to include?

use Illuminate\Support\Facades\Auth;

Auth::logoutOtherDevices($currentPassword);

Answer

 public function authenticated(Request $request)
    {
        Auth::logoutOtherDevices($request->password);
        if (Auth::check() && Auth::user()->role_id == 1) {
            return redirect('/admin/dashboard');
        }
        $config = DB::table('config')->get();
        /*starts*/
        $id = Session::get('selected_plan_id');

        if(empty($id))
        {
            return redirect('/user/dashboard');
        }
        else
        {
            $selected_plan = Plan::where('plan_id', $id)->where('status', 1)->first();
    
            if ($selected_plan == null) {
                alert()->error('Your current plan is not available. Choose another plan.');
                return redirect('/user/plans');
            } else {

                if ($selected_plan == null) {
                    return view('errors.404');
                } else {

                    return redirect('/user/rediretoCheckout');
                }
            }
        }   

    }

you need to include Auth::logoutOtherDevices($request->password); win authencication code

Solution

You may use the logoutOtherDevices method provided by the Auth facade. This method requires the user to confirm their current password, which your application should accept through an input form: Add in Controller-> Login Mehthod

use Illuminate\Support\Facades\Auth;

Auth::logoutOtherDevices($currentPassword);
