Cara setting Lupa password di script toko online CI.

Assalamualaikum,.. Mungkin maksudnya disini email konfirmasi untuk lupa password tidak masuk pada inbox alamat emailnya? benar begitu? jika benar maka untuk konfigurasi pengiriman email bisa ganti ke SMTP Gmail saja, karena beberapa hosting tidak mengizinkan pengiriman email dengan fungsi mail secara lansung.
 
Berikut tahapan mengubah ke SMTP Gmail :
buka file : C:\xampp\htdocs\toko_onlinemu\application\controllers\Auth.php
pada baris 120 cari : 
$this->email->from($identitas['email'], $identitas['nama_website']);
$this->email->to($email_tujuan);
$this->email->cc('');
$this->email->bcc('');
 
$this->email->subject($subject);
$this->email->message($message);
$this->email->set_mailtype("html");
$this->email->send();
 
$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'utf-8';
$config['wordwrap'] = TRUE;
$config['mailtype'] = 'html';
$this->email->initialize($config);
 
Ubah menjadi :
$config['protocol']    = 'smtp';
$config['smtp_host']    = 'ssl://smtp.googlemail.com';
$config['smtp_port']    = '465';
$config['smtp_timeout'] = '7';
$config['smtp_user']    = "alamat_email@gmail.com";
$config['smtp_pass']    = "password gmail disini...";
$config['charset']    = 'utf-8';
$config['newline']    = "\r\n";
$config['mailtype'] = 'html'; 
$config['validation'] = TRUE; 
$this->email->initialize($config);
$this->email->from("$identitas[email]", "$identitas[nama_website]");
$this->email->to($email_tujuan);
$this->email->cc('');
$this->email->bcc('');
$this->email->subject($subject);
$this->email->message($message);
$this->email->send();
