Is there something called CID in MetaTrader?

[Random R]

I have an account with a prop firm.

The prop firm claims that MetaTrader stores an ID called CID on the company's server, and based on this ID, they claim I have logged into my account from multiple different systems. I wanted to ask if such an ID is indeed stored by MetaTrader on the server side? If it is stored, what is this ID derived from? For example, does this ID change if hardware components like the network card or hard drive are changed, or if Windows is reinstalled?

If they show you CID - it’s their private monitoring system, not something coming from MetaTrader.

They say that MetaTrader, in the mobile or desktop version, sends a hardware identifier to the server. Even if their own monitoring system generates this ID, MetaTrader definitely sends a hardware identifier to the server, because trading is only done through MetaTrader and there is no other system that can generate this ID. Are you sure that MetaTrader does not send anything to the server other than the login ID and password?"
