What is a Network Security Key and where to Find it

The network security key is better known as the WiFi or Wireless Network Password. This is the password that you use to connect to a wireless network. Each access point or router comes with a preset network security key that you can change on the settings page of the device.

The network security key is important because it protects your network from intruders. Without the key, you can’t connect to the wireless network. So keeping your network security strong is important.

Now it’s pretty common to forget the security key of your wireless network. Most default keys are not easy to remember and you only enter them once or twice a year.

In this article, I will explain where you can find your network security key on your router, access point, or computer (if you already have a connection) and how you can change it.

What is a Network Security Key?

A network security key is a password that protects your wireless network. The network security key is protected with encryption using one of the following standards, WEP, WPA, WPA2, or WPA3. To connect to a wireless network you will need to know the password of the network and which encryption method is used.

New routers or access points always come we a preset network security key, existing of random numbers and letters. These passwords are often hard to remember, but you can most of the time change them in the settings of the device.

When you don’t have a network security key set for your wireless network, then everybody within the range of your network can access your internet connection and home network devices (computers, printers, etc).

Different types of Network Security Keys

So let’s first start with some background info on the different types of security keys that can be used to protect your wireless network. In short, always use at least WPA2 to secure your wireless network, and don’t use WEP anymore.

WEP – Wired Equivalent Privacy

The WEP security key is one of the older types of keys that are used for wireless networks. It uses a 40-bit key for encrypting the data between your router and computer.

WEP keys shouldn’t be used anymore. The encryption can be cracked within a minutes, exposing your network to hackers. Most modern access points and routers don’t support WEP anymore.

WPA – WiFi Protected Access

These days we use mainly WPA2, and soon WPA3, to protect our wireless network. WPA was the first version of the WiFi Protected Access protocol. It uses a temporary key (TKIP) to set up the connection. Each packet is protected with a new 128-bit key, preventing unauthorized access to the data.

WPA2 (WiFi Protected Access 2)

WPA2 is the successor of the WPA protocol. It’s better protected with strong AES encryption, making it a secure wireless protocol to use. WPA2 was introduced in 2006, so pretty much all devices that you use these days support it.

Atleast use WPA2 to protect your home and office network. Starting in 2018, you might see the first devices that support WPA3, but it may take a couple of years before it’s fully supported.

WPA3 (WiFi Protected Access 3)

WPA3 is the latest wireless network encryption standard that we can use. All devices from 2020 support WPA3. The difference with WPA2 is a new and better encryption method (AES-256) and a more secure initial key exchange method.

Besides the security, with WPA3 it’s also easier to connect wireless devices that don’t have a display (screen), and even with a weak wireless network password, the new protocol will still be able to secure your connection.

How to Find your Network Security Key

There are different scenarios when you are looking for the key to the wireless network. You just bought a new router or access point or you want to give another device (mobile phone or computer) access to an existing wireless network but you don’t remember your key anymore.

If you have a device that is already connected to the wireless network then you can find the key in the network settings. Each device that is connected to wireless network stores the key so it can reconnect automatically when the network comes into range.

Network Security Key WiFi

If you have a new router or access point then the default wireless network key for your wifi can be found on a label on the bottom or back of the device. Unfortunately, each manufacturer is using a different label for it, but look for a key that is labeled with one of the following (similar) phases:

• Password (key)
• Wireless password
• WPA(2) key

You will find it close to the (Wireless) Network Name (SSID). Use this keyphrase to connect to your wireless network. Now it’s important to change the default key, so make sure you continue reading this article.

If you have ever changed the key of your wireless network and you don’t have a device that is connected to the network, then your only option is to look the password up in the router or access point self. Follow these steps to recover the key.

Network Security Key on Windows 10

If you have a Windows 10 device that is already connected to the wireless network, then you can relatively easily find the network security key in Windows 10

1. Right-click on the Start Menu (a context menu will appear)
2. Click on Network Connections
3. Scroll down and click on Network and Sharing Center
4. Click on your Wireless network (starting with Wi-Fi)
5. Click on the Wireless Properties button
6. Go to the Security Tab. You will see that your password is masked
7. Select the “Show characters” checkbox, your network security key will be revealed.

Finding the wifi password on a Mac

Also on a Mac, you can find the key pretty easily:

1. Click on the search icon (magnifying glass)
2. Search for Keychain Access
3. In the Keychain Access screen search in the top right corner for your Wifi network
4. Double-click on your network
5. Select the Show Password checkbox
6. You need to enter the password of your Mac

Change your WiFi password

It is important that you change the default WiFi Password (Network Security Key) when you get a new Router or Access Point. Your wireless network is broadcasted to everyone that is in range of your device, so a strong password is important.

Now every router or access point is different. But I will provide you with some of the first steps to log in to your router and give you a general direction.

First, we need to know the IP Address of the router. 90% of the routers have the following address: 192.168.1.1 or 192.168.0.1. You can look it up in the manual or find it on your computer.

Right-click on start > select run and type cmd .

In the black command box type ipconfig and press . You will see a couple of lines, we are looking for the line Default Gateway and the address behind it.

1. Open your browser and type 192.168.0.1 (or the address that you found with ipconfig ) in the address bar and press enter
2. You will see the login page of the router. Find the login credentials in the manual (links below)
3. Find a page with Wireless, Wireless Security or Wireless Settings
4. Select WPA atleast, but the best encryption is WPA2.
5. Change the passphrase, key or password of the wireless network to something strong (atleast 10 characters, a symbol and number)
6. Reconnect your devices with the new password.

Network Security Key Mismatch

When you try to connect to a wireless network and you get the error, Network Security Key Mismatch, then the key/password that you are using is incorrect.

There are a couple of common reasons why you might get the error about the mismatch:

• Wrong password – The most common reason is that you simply entered the wrong password. Double-check the password, keep in mind that it’s case-sensitive. Sometimes it helps to type the password first in Notepad or Word so you can see what you type. Then copy-paste it into the wireless network password field.
• Incompatible device – Some older devices don’t support the new WPA2 network passwords. So you may see the network, but your device can’t connect to it because it doesn’t support the same network security key protocol.
• Router or access points hang – Not often, but sometimes a router or access point simply hangs. A quick reboot of the router (pull the plug) may solve the issue.

If nothing works then you will have to reset the wireless network. Now you have two options here, you can create only a new wireless network or reset the whole router/access point.

To create a new wireless network, log in to your router or access point and go to the wireless network tab. Remove the old network and create a new one. Make sure you choose a strong password, I recommend using a password manager to keep your passwords safe.

The other option is to reset the whole router. Make sure you look up the default router login credentials and make sure you keep the internet settings at hand. With some routers, you can create a backup of the configuration, if possible, do that before resetting the device.

Conclusion

I hope this article helped to find your network security key. Always make sure you use a strong and unique password for you r wireless network. If you want to know more about setting up your home network, make sure you check this article.
