Symfony2 Need to send password to API - symfony

Question

how do i get the password eneterd via a costum user provider. I found this question:
Symfony Security / Custom User Provider : How to get the login password within the custom User Provider?
Which says i would have to overrise the loadUserByName method, and add the password as a parameter, the issue is that i cannot find the file he overrides:
security_listeners.xml
Where is this file located?
I found the:
$user = $this->userProvider->loadUserByUsername($username);
call in the DOAAuthenticationProvider, and i see that the method takes:
protected function retrieveUser($username, UsernamePasswordToken $token)
as augments, i asume i need to pass the password there, and then pass it to loadUserByName, which calls my costum userprovider method.
Any help on how to achieve this is appreciated.

You can create an AuthenticationHandler on your bundle. and the on successful login fetch the password from the token.
in services.yml:
security.authentication.success_handler:
class: Wix\UserBundle\EventListener\AuthenticationHandler
arguments: ["#security.http_utils", {}]
tags:
- { name: 'monolog.logger', channel: 'security' }
And sample class:
class AuthenticationHandler extends DefaultAuthenticationSuccessHandler
{
/**
* This is called when an interactive authentication attempt succeeds. This
* is called by authentication listeners inheriting from
* AbstractAuthenticationListener.
*
* #param Request $request
* #param TokenInterface $token
*
* #return Response never null
*/
public function onAuthenticationSuccess(Request $request, TokenInterface $token)
{
$response = new RedirectResponse('/');
$response->setStatusCode(200);
return $response;
}
}
