Hello

I set up some Middleware before my controller ( and have to change the controller to PSR handler ), I start work on the login handler Instead login controller and I don’t have access to MVC plugins in the handler.

DO you have any examples of Authentication in handler and Authentication adaptor?

I want to make sure I am in true way in this part

Best

In a controller the [`identity` plugin](https://docs.laminas.dev/laminas-mvc-plugin-identity/) can be used. This plugin uses the [`AuthenticationService` of laminas-authentication](https://docs.laminas.dev/laminas-authentication/intro/#introduction):

> <https://github.com/laminas/laminas-mvc-plugin-identity/blob/d22e7fb74f0395828df5cd42ed55d23a98569ed1/src/Identity.php#L56-L60>

So inject the `AuthenticationService` directly into your handler and you can work with it.
