Hey There, I am Sofia carter. The answer to what is a WPS pin is WPS is short for Wi-Fi Protected Setup. To make the connection between routers and mobile devices as quick and easy as possible, this standard was developed. WPS only works with wireless networks that employ WPA Personal or WPA2 Personal security protocols to encrypt the password. WLANs using WEP security, which can be broken by anybody with a minimum set of tools and abilities, do not support WPS.
