The fact you don't do it means you actually don't care at all about your privacy. It takes 5 minutes to bring every member in an household in the living room or kitchen and assist them to change the wifi password on their device.

You can even prepare for it by printing the details + qrcode beforehand.

Connecting to a wifi network is one of those things every terminally connected non tech savy people are able to do these days.
