Descriptions :The WPS protocol is a simple way to connect a device to a router by exchanging a PIN. Instead of knowing the WEP, WPA, or WPA2 key, which can be tedious and complicated, we only need the WPS protocol. Send the router a PIN that consists of only eight digits. When the router receives this PIN, it sends the device all the necessary data to connect to the network. If you know the key of the Wi-Fi network, the device connects.
