    Authenticator && authenticator

Description

Parameters

Name	Description
authenticator	Object that will be stored (move-constructed or by reference) and used for authentication. It needs to satisfy `is_authenticator` concept.

	Important
	This function takes action when the client is in a non-operational state, meaning the `mqtt_client::async_run` function has not been invoked. Furthermore, you can use this function after the `mqtt_client::cancel` function has been called, before the `mqtt_client::async_run` function is invoked again.
