How do users connect IOT device to WiFi?
Kasper:
And the plot thickens... more good ideas. Thank you.

Electric Imp used a photodiode to allow an app to flash a pattern on the screen that conveys the credentials to the device. You could do something similar with an audio modem and the phone's speaker and a mic in the device.

That sounds pretty slick, specially since I'm thinking about adding an illumination sensor anyways.

ESP32 and ESP8266 support a feature called ESP Touch, it use only Wifi but it require an application running on a smartphone either Android or Ios, they have samples application if you want to edit it yourself. The idea is that this application will broadcast wifi credentials through the router on which the phone is already connected, while the module will be sniffing for those frames. You can connect multiple units at once using this method.
ESP32 support WPS as well, so a button on the device can be used, sample code can be found in ESP_IDF.

These sound like the easiest solutions for the users but would they be venerable to users' neighbors who are constantly sniffing or other hackers?

Didn't the ElectricImp gang manage to get a patent on the "flashing-light" method of setup?
IMHO, another example of something that is both obvious and very likely "prior-art" getting a patent.

I guess I'll have to use a blinking-light instead of flashing-light ;)

Very true. A method that is easy for the general public would be great to see. The flashing communication sounds pretty neat and much easier for Joe Public than editing text files and requiring a thumb drive (especially on a phone).
For me, the only drawback is that it requires an app. I'm so tired of the prevalence of apps and companies insisting that you must install their app to do rudimentary (and often, duplicate) things. A web page could probably do the flashing transmission.
Wouldn't the Timex Datalink watch be prior art for ElectricImp's patent? Maybe they worked around it.
