Hey There, I am Sofia Carter. The WPS stands for the Wi-Fi protected setup. It is a Wi-Fi network security standard used for establishing a successful connection between the Wi-Fi devices and router easier and faster. The WPS pin only works with a Wi-Fi network that uses the password encrypted with WPA/WPA2 security protocol. To know more about what is a wps pin, you can contact the internet service provider. Also. You can refer to the user manual of your router. In the user manual, you can find all the details about the WPS pin, connection, and other set up related information.
