Account piracy? - eviltoast

I know this sounds fucking stupid and it probably us but I’ll ask anyway. Is there any way to pirate an account? Specifically a mc have account, mainly for multiplayer. Any other workarounds can be used for piracy?

Mainly asking cos some of my IRL friends suggested we should play mc and while I have an account I dislike playing on PC and don’t want to sync a personal account to an unsecured device.

Is this whole thing impossible and dumb? Is this the wrong community? I need advice
