To make it more secure: I would change following line: if($params['pin'] != $user->getPin()) {
to:
if($params['pin'] !== $user->getPin()) {
Or
$user_input = (string) $params['pin'];
if($user_input != $user->getPin()) {
note: getPin => must always return string.
Nice, thanks for the solutions! Never trust user input
