I am planning to purchase a program that comes with an App that allows you to control the program via phone. The developer told me that the connection will be done via an extra WIFI box connecting to my computer. I plan to give this WIFI's password to friends and family.
Questions:
Does this open my PC to attacks?
My pc connects to the home network via cable. Does opening up a WIFI like this expose my home network to attacks?
Is there a way to stop people from connecting to this WIFI network with devices other than a phone (I am mostly worried about infected laptops)
