A network security key is essentially the password used to protect a wireless network, such as a Wi-Fi network. It acts as a security measure that controls who can connect to the network, preventing unauthorized access and helping to encrypt data transmitted over the network
. This key is often referred to by various names including Wi-Fi password, wireless password, network password, or WEP/WPA key, but they all mean the same thing: the code required to connect a device to a secured wireless network
. Network security keys work by authenticating devices trying to connect, ensuring only authorized users can access the network and its resources. Without the correct key, devices cannot join the network, keeping it safe from intruders and cyberattacks
. There are several types of network security keys based on encryption protocols:
- WEP (Wired Equivalent Privacy): An outdated and insecure protocol, no longer recommended.
- WPA (Wi-Fi Protected Access): An improvement over WEP but still vulnerable to some attacks.
- WPA2 (Wi-Fi Protected Access 2): Uses strong AES encryption and is widely used for secure networks.
- WPA3 (Wi-Fi Protected Access 3): The latest and most secure protocol, offering stronger encryption and easier device setup
Your network security key is usually found on your router (often on a sticker) or can be viewed and changed in your device’s network settings or router admin page
. In summary, the network security key is critical for securing your Wi-Fi network by controlling access and encrypting data, thereby protecting your network and connected devices from unauthorized use and cyber threats
