How devices such as smart Wi-Fi power plugs and Wi-Fi ip cameras connect to a private Wi-Fi network ?
The usual steps are the following :
You buy the device
You install the maker application on your smartphone
You discover the device trough the application
You set up your private Wi-Fi password network on the device trough the application
The device reboot
Then the device appears on your private network.
What are the technologies/protocol behind that steps ?
Let's say that in 10 years the maker application will not exists anymore. How I will be able to connect my device to my network ? What about password security during step 4?
