What Is a Network Security Key and How Is It Keeping Your Network Secure?

If you’ve ever snooped around in your Wi-Fi settings or tried to connect a new device to your home network, you’ve likely stumbled upon the term "network security key."

It may sound technical and a bit scary, but don’t worry—this Mysterium VPN blog post will break it down in a way that even your grandma could understand (assuming she’s not already a tech wizard).

The Basics: What Is a Network Security Key?

Is the network security key the same as the password? Yes, yes it is!

A network security key, or put simply, your Wi-Fi password, is a type of password used to protect your Wi-Fi network. It encrypts the data that travels between your connected devices and the router, ensuring that your wireless network and internet connection remain private and secure.

This encryption prevents unwanted strangers from accessing your network and data.

Types of Network Security Keys

There are several types of network security keys, each offering different levels of security:

1. Wired Equivalent Privacy (WEP): One of the oldest security protocols. It’s not very secure by today’s standards and is mostly obsolete for that same reason.
2. Wi-Fi Protected Access (WPA): A better and safer version of WEP. WPA uses the Temporal Key Integrity Protocol to boost your security by creating a new encryption key for each new message sent over the network.
3. Wi-Fi Protected Access II (WPA2): Currently the most common and secure protocol for most Wi-Fi networks, using Advanced Encryption Standard encryption.
4. Wi-Fi Protected Access III (WPA3): The latest security protocol, providing even stronger encryption and protection.

How Does a Network Security Key Work?

When you connect to a Wi-Fi network and enter the network security key, your device and the router are essentially greeting by shaking hands.

During this "handshake", the correct password (or key) is verified, and an encrypted connection is established.

The encrypted connection ensures that any data transmitted over the network is scrambled and can only be decoded by devices with the correct key.

Common Security Protocols

• WPA2 and AES Encryption: Almost all Wi-Fi networks today use WPA2 with AES encryption. AES is a robust encryption standard that secures your data from unwanted access. It’s like having a super-strong lock on your front door—only those with the correct key can come inside.
• WPA3: This newer protocol enhances security with more complex encryption techniques and better protection against brute-force attacks. It’s gradually becoming the standard for newer devices and networks.

What Is Network Security Key for Hotspot?

A network security key for a hotspot is the password that you set up to secure your mobile or portable hotspot connection. This key ensures that only authorized users can connect to your hotspot and use your internet connection.

When you create a hotspot on your smartphone, tablet, or dedicated mobile hotspot device, you typically configure a network security key, often referred to as the Wi-Fi password. To find or set the network security key for a hotspot:

On an Android Device:
