Wi-Fi Protected Setup (WPS) is a network security standard designed to simplify the process of connecting devices to a wireless network. It allows users to easily add devices, such as printers or smartphones, to their Wi-Fi without needing to enter a long password. WPS can be activated using a physical button on the router or by entering a PIN. When WPS is enabled, users can connect their devices by pressing the WPS button on the router and the device they want to connect. This process establishes a secure connection automatically, making it user-friendly for those who may not be tech-savvy.
