- FerdSlav 5y agoPAF can be thought of as basically a broadcast message to any and all WiFi devices in the area, regardless of if they are connected to the same access point or IP network. In the case of someone like Amazon, a device when it is first powered on can broadcast out looking for other Amazon WiFi devices in the home and receive the credentials from them.
