keep user logged in after closing the browser

Firstly, Is it safe to keep users logged in using cookies? I tried to keep users logged in so they needn't login everytime they open the browser. I did some changes in the authenticatesUsers.php trait as follows but users still log out when they close the browser. How can I do that?

    /**
     * Send the response after the user was authenticated.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Http\JsonResponse
     */
    protected function sendLoginResponse(Request $request)
    {
        $request->session()->regenerate();

        $this->clearLoginAttempts($request);

        if ($response = $this->authenticated($request, $this->guard()->user())) {
            return $response;
        }

        $ID=auth()->user()->id;$NAME=auth()->user()->name;
        session()->put(['user_id'=>$ID,'user_name'=>$NAME]);
        $sess=session()->get('user_id');
        Cookie::queue('sessCook',$sess,3600*24*30*5);   
        
        return $request->wantsJson()
                    ? new JsonResponse([], 204)
                    : redirect()->intended($this->redirectPath());
    }
