     $this->db->update($this->tables['users'], array('forgotten_password_code' => $key), array('email' => $email));

     return $this->db->affected_rows() == 1;
}

public function change_password($identity, $old, $new)
{

Code:

function forgot_password()
{
  $this->form_validation->set_rules('email', 'Email Address', 'required');
  if ($this->form_validation->run() == false)
  {
   //setup the input
   $data['email'] = $this->input->post('email');
  
  
   //set any errors and display the form
   $data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
   $this->load->view('auth/forgot_password', $data);
  }
  else
  {
   //run the forgotten password method to email an activation code to the user
   $email = $this->input->post('email');
   $forgotten = $this->ion_auth->forgotten_passwd($email);
   $salt    =

   if ($forgotten)
   { //if there were no errors
    $this->session->set_flashdata('message', $this->ion_auth->messages());
    redirect("auth/login", 'refresh'); //we should display a confirmation page here instead of the login page
   }
   else
   {
    $this->session->set_flashdata('message', $this->ion_auth->errors());
    redirect("auth/forgot_password", 'refresh');
   }
  }
}

//reset password - final step for forgotten password
public function reset_password($code)
{
  $reset = $this->ion_auth->forgotten_passwd_complete($code);

  if ($reset)
  {  //if the reset worked then send them to the login page  
   $this->session->set_flashdata('message', $this->ion_auth->messages());
   redirect("auth/login", 'refresh');
  }
  else
  { //if the reset didnt work then send them back to the forgot password page
   $this->session->set_flashdata('message', $this->ion_auth->errors());
   redirect("auth/forgot_password", 'refresh');
  }
