            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');

        });
    }

    /**

    {
        Schema::dropIfExists('members');
    }
}

Change in SigninController.php File:

app/Http/Controllers/Auth/SigninController.php

namespace AppHttpControllersAuth;

use AppHttpControllersController;
use IlluminateFoundationAuthAuthenticatesMembers;
use IlluminateHttpRequest;
use AppHttpRequests;
use AppUser;
use DB;

class SigninController extends Controller
{

    use AuthenticatesMembers;

    /**
     * Where to redirect members after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    public function login(Request $request)
    {
        $this->validate($request, [
            'email' => 'required',
            'password' => 'required',
        ]);

        $member = DB::table('members')->where('email', $request->input('email'))->first();

        if (auth()->guard('web')->attempt(['email' => $request->input('email'), 'password' => $request->input('password')])) {

            $new_sessid   = Session::getId(); //get new session_id after member sign in

            if($member->session_id != '') {
                $last_session = Session::getHandler()->read($member->session_id); 

                if ($last_session) {
                    if (Session::getHandler()->destroy($member->session_id)) {
                        
                    }
                }
            }

            DB::table('members')->where('id', $member->id)->update(['session_id' => $new_sessid]);
            
            $member = auth()->guard('web')->member();
            
            return redirect($this->redirectTo);
        }   
        Session::put('login_error', 'Sorry, Your email and password wrong!!');
        return back();

    }

    public function logout(Request $request)
    {
        Session::flush();
        Session::put('success','Good Lcuk, you are logout Successfully');
        return redirect()->to('/login');
    }
}

Include in app.blade.php File:

resources/views/layouts/app.blade.php

<script src="https://www.gstatic.com/firebasejs/4.9.1/firebase.js"></script>
<script type="text/javascript">
var session_id = "{!! (Session::getId())?Session::getId():'' !!}";
var member_id = "{!! (Auth::member())?Auth::member()->id:'' !!}";

// Initialize Firebase
var config = {
    apiKey: "firebase.api_key",
    authDomain: "firebase.auth_domain",
    databaseURL: "firebase.database_url",
    storageBucket: "firebase.storage_bucket",
};
firebase.initializeApp(config);

var database = firebase.database();

if({!! Auth::member() !!}) {
    firebase.database().ref('/members/' + member_id + '/session_id').set(session_id);
}

firebase.database().ref('/members/' + member_id).on('value', function(myssval) {
    var v = myssval.val();

    if(v.session_id != session_id) {
        toastr.warning('Your Member account login from another device!!', 'Warning Alert', {timeOut: 3000});
        setTimeout(function() {
           window.location = '/login';
        }, 4000);
    } 
});
