What is the network security key?

A network security key, often referred to as a Wi-Fi password, is a password that secures access to a wireless network. It encrypts the data transmitted between a device and a router, preventing unauthorized users from accessing the network. This key protects a Wi-Fi network from snooping and unauthorized access.
