Staff have mentioned many times on this forum (as have many community members) that port forwarding your Hubitat is a bad idea. So many times that, yes, each one of those words is a different hyperlink that will take you to someone saying so. 
Anyone who is doing this anyway should know better than to leave it open if they do, but it's not recommended in any case.
Great advice for you to share as a reminder! Anyone looking to do this should consider a VPN instead (you can host one yourself on something as simple as a Raspberry Pi with PiVPN, or many home routers have such a feature built-in).
