What is a Network Security Key? How do I locate it?

Safeguarding your Wi-Fi network is paramount in the increasingly connected world. But What is a Network Security Key, and why is it crucial for your online safety? A Network Security Key, often referred to as a Wi-Fi password, is a code that protects your wireless network from unauthorised access. Without it, anyone within range could potentially connect to your network, compromising your personal data and slowing down your internet speed.  

Have you ever wondered how to locate this essential key on your devices? Be it using a Mac, Windows, Android, or iPhone, finding your Network Security Key is simpler than you might think. In this blog, we’ll guide you through the steps to retrieve your key, ensuring your network remains secure. Ready to take control of your Wi-Fi security? Let’s dive in and explore the answers to these critical questions.

What is a Network Security key?  

A Network Security Key functions as the password for a Wi-Fi network. It typically comprises 8-12 characters, biometric data, or a digital signature, serving as a crucial layer of cyber protection to ensure a secure connection between the network and connected gadgets. Without this security key, a private network is susceptible to unauthorised access. 

Just like account passwords, it’s essential to use a strong Network Security Key to safeguard against malicious activities on your business network, prevent unauthorised access to your devices, and minimise the risk of data breaches.
 

Types of Network Security Keys  

Most Wi-Fi networks utilise one of four types of Network Security Keys. These security keys are often listed on routers to indicate the type of encryption available. Each protocol is designed to protect Wi-Fi networks from hackers, but they differ in their encryption standards. Here’s a wider look at the four types of Network Security Keys: 

1) WEP (Wired Equivalent Privacy) 

This is the first Wi-Fi security protocol. It used a static encryption code, which is now outdated and easily cracked with downloadable decryption software. As a result, WEP provides very limited security and is not recommended for use. In 2003, the Wi-Fi Alliance declared that WPA had superseded WEP. 

2) WPA (Wi-Fi Protected Access) 

WPA succeeded WEP and provided enhanced security. It employs a dynamic message integrity check algorithm known as Temporal Key Integrity Protocol (TKIP), which generates a unique encryption key for each packet transmitted across the network. Despite its improvements over WEP, WPA is still vulnerable to increasing cyberattacks. 

3) WPA2 (Wi-Fi Protected Access 2) 

Wi-Fi Protected Access 2 (WPA2) is the successor to WPA, incorporating the Advanced Encryption Standard (AES) to enhance security and replace the less secure TKIP system. AES provides strong encryption for all data transmitted over a Wi-Fi network. While WPA2 can still be compromised, it offers better protection against unauthorised access compared to previous protocols. 

4) WPA3 (Wi-Fi Protected Access 3) 

Wi-Fi Protected Access 3 (WPA3) is the recent protocol, designed to replace WPA2, though WPA2 remains widely used. WPA3 offers superior Network Security, allowing devices to join a network without transmitting a password. Instead, users sign in using a QR code or NFC tag. Most routers certified post-2018 are compatible with WPA3, and every router certified after July 1, 2020, are required to support it.

How do you find the Network Security Key on a router/modem?  

Locating the Network Security Key on your router or modem is simple. Here’s how you can find it: 

a) Check the Router or Modem: Most devices have a sticker or label displaying the default Network Security Key, usually found on the bottom or back. Look for terms like “WPA Key,” “WPA2 Key,” “Wireless Key,” or “Password.” 

b) Access the Router’s Settings Page: If the default key has been changed or the sticker is missing, access the router’s settings page via a web browser. Connect your device to the router, open a browser, and enter the router’s IP address (commonly 192.168.1.1 or 192.168.0.1). Log in with the router’s username and password. Later, you can navigate to the wireless settings section to find the Network Security Key. 

c) Check Router Documentation: If you still can’t find the key, refer to the router’s user manual or the manufacturer’s website for specific instructions. 

How do you look up the Network Security Key on a Mac or Windows device?   

If you’re connected to a network but can’t recall the Network Security Key, you can find it on a device that’s already connected. 

1) On a Mac 

a) Open “Applications,” then go to “Utilities,” and choose “Keychain Access”
 

b) Look for your Wi-Fi network name, and double-click it
 

c) Select “Show Password”

d) Enter your Mac password, and the Network Security Key will be revealed
