And at the end of the story there’s still an unlimited amount of devices that possess the key. So what is the gain?

- franga2000 6y agoThe key is only useful to the first device that gets it. It's generated for each transaction and only valid once. The devices (let's say two phones) communicate directly and once that's done, the connection closes. To add another device, the phone weill generate a new key and a new QR code.
- tinus_hn 6y agoYeah that’s great but at the end of the story each phone has the PSK because that’s what it uses to actually connect to the wireless network.
