The network security key: what it is and where to find it 

Indice dei argomenti

The security of our Wi-Fi networks is essential to protect personal and business data. A key component of this security is the network security key.

We have already addressed network security keys in previous articles, but we have received further questions that we will answer in this article. 

What exactly is a network security key? Where to find it and how to use it? This article will explore these questions in detail.

What is a network security key? 

The network security key is a password or code that allows access to a Wi-Fi network. This key is crucial to ensure that only authorized users can connect to the network.

The network security key can be of various types, including WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access), each offering different levels of protection. 

Where to find the network security key 

The network security key can be found in different ways depending on the device and operating system used.

For most routers, the key is usually printed on a label attached to the device itself. If it is not visible, it can be retrieved by accessing the router’s settings via a web browser. 

For Windows devices, the key can be found by accessing the “Wireless Properties” of the network connection and selecting the “Security” tab.

After selecting “Show characters,” the network password will be visible.

On a Mac, the network security key can be found in the Airport Utility or by accessing system preferences and selecting Wi-Fi network settings. 

Importance of the network security key 

Using a strong network security key is essential to protect your Wi-Fi connection from unauthorized access. A weak key can be easily breached, putting personal and business data at risk.

For this reason, it is important to create a complex key that includes a combination of uppercase and lowercase letters, numbers, and symbols. 

How to create a complex network security key 

Here is a step-by-step guide to creating a strong security key: 

• Use a password generator
  Use an online password generator to create a complex and random security key. Make sure it is at least 16 characters long. 
  
• Include various types of characters 
  A complex security key should include a combination of: 

ppercase letters (A-Z) 

Lowercase letters (a-z) 

Numbers (0-9) 

Special characters (@ # $ % & *)

• Avoid personal information
  Do not use personal information like names, birthdates, or common words. This makes the key harder to guess. 
• Use a password management system 
  Use password management software to store your security key. This will help you remember it and keep it secure. 
• Change the key periodically
  To maintain high security, change your security key every 6 to 12 months. 

Steps to set the key on your router 

• Access your router
  Connect your computer to the router via an Ethernet cable and open a web browser. Type the router’s IP address (usually 192.168.1.1 or 192.168.0.1) into the address bar. 

• Login
  Log in with the router’s username and password. This information is often found on the router’s label or in the user manual. 

• Configure Wi-Fi security
  Find the wireless security settings, usually under “Wireless Settings” or “Security.” 

• Set WPA3 or WPA2
  Make sure to use WPA3 (if available) or WPA2 as the encryption method. Avoid WEP as it is less secure. 

• Enter the new security key
  In the “Passphrase” or “Pre-Shared Key” section, enter the complex security key you created. 

• Save the changes
  Apply and save the changes. The router may reboot to apply the new settings.

Additional tips 

• Hide the SSID
  Consider hiding your network’s SSID to make it less visible to others. 

• MAC filtering
  Configure MAC address filtering to allow only specific devices to connect to the network. 

Types of network security keys 

There are different types of network security keys, each with varying levels of protection: 

• WEP (Wired Equivalent Privacy)
  This is an older wireless network security technology that offers basic protection. However, it is considered less secure than newer technologies and is no longer recommended for use. 

• WPA (Wi-Fi Protected Access)
  Offers better security than WEP. WPA2, an advanced version, is currently the most commonly used standard for protecting Wi-Fi networks. 

How to view the network security key 

Sometimes, it may be necessary to view the network security key, for example, to connect a new device. Here’s how: 

On Windows

Go to "Control Panel" 

Select "Network and Internet" 

Go to "Network and Sharing Center" 

Select the Wi-Fi network you are connected to 

Click on "Wireless Properties" 

Select the "Security" tab

Check "Show characters" to view the password

On Mac

Go to "System Preferences" 

Select "Network" 

Select the desired Wi-Fi connection 

Click on "Advanced" 

Go to the "Wi-Fi" tab and select the network

Click "Show password" (you may be prompted to enter the administrator password)

In conclusion, we can say that the network security key is a crucial element for keeping your Wi-Fi connection secure. Knowing where to find it and how to use it can make the difference between a protected network and a vulnerable one. Remember to update your Wi-Fi password regularly and use the most advanced security settings available on your router.
