How to Find Your Network Security Key
by Usama Muneer
Have you ever tried to connect a new device to Wi-Fi but couldn’t remember the password? Or maybe a friend asks, “Hey, what’s your Wi-Fi?” and you completely blank out. We’ve all been there! That mysterious combination of letters and numbers, known as the network security key, is what keeps your wireless network safe and secure. But what exactly is it, and how do you find it?
A network security key is simply your Wi-Fi password—the code that allows devices to connect securely to your network. Think of it as a digital lock that prevents unauthorized users from accessing your internet. Without it, anyone could slow down your connection or even snoop on your data.
WPA (Wi-Fi Protected Access) and its variants are crucial knowledge for the Network+ and CCNA exams. There are different types of network security keys, including:
WPA: An older protocol, still in use but less secure.
WPA2: The most common and widely used, offering strong encryption and security.
WPA3: The latest version, providing enhanced protection against cyber threats.
In this article, we’ll walk you through a simple, step-by-step guide to help you find your network security key—whether you're at home or running a small business. If you've misplaced your Wi-Fi password or just need to locate it, here's what you need to know.
What are the Prerequisites to Finding a Network Security Key?
Before we get into the process of finding your Wi-Fi password, there’s one thing you’ll need: access to a device that’s already connected to your Wi-Fi network. Whether it’s a Windows PC, Mac, or mobile device, make sure you’re logged in and connected to the network you're trying to access. A quick heads-up—administrator privileges might be required on some systems. But once you have that, you’re good to go.
How to Find a Network Security Key on Windows
Step 1: Open Network and Internet Settings
First, click on the Wi-Fi icon in your system tray (bottom right corner of your screen).
Select Network & Internet Settings.
From there, head to Status and click on Network and Sharing Center. You’re one step closer.
Step 2: View Network Properties
Find the Wi-Fi network you’re connected to and click on its name.
Next, click Wireless Properties—you’ll find this under the Connection tab.
Now, head to the Security tab and check the box that says Show characters. Boom! Your network security key (Wi-Fi password) will be revealed.
How to Find a Network Security Key on macOS
Step 1: Open Keychain Access
First, open Spotlight (Command + Space) and type in “Keychain Access” or go to Finder > Applications > Utilities > Keychain Access.
Once you’re in Keychain Access, search for the name of your Wi-Fi network in the list of saved passwords.
Step 2: Show the Password
Click on your Wi-Fi network name and check the box next to Show Password.
A prompt will appear asking for your Mac administrator password—enter it, and just like that, your network security key will be uncovered.
How to Find a Network Security Key on a Router
Step 1: Locate the Router
Find your router (the physical box that makes your internet work). You’ll often spot a label on it with default login credentials like the username and password.
Step 2: Log into Router Settings
Open a web browser and type in your router’s IP address (usually 192.168.1.1 or 192.168.0.1) into the address bar.
Log in using the router’s default username and password (most likely admin for both, unless you’ve changed it).
Step 3: Find the Wireless Settings
Once you're in, look for the Wi-Fi settings or Wireless Settings section in the router's menu.
The network security key should be listed under the Wireless Security or Wi-Fi Settings tab—this is your key to unlocking your connection.
How to Find a Network Security Key on Mobile Devices
For Android
Step 1: Open the Settings app, then tap on Network & Internet and select Wi-Fi.
Step 2: Tap on the connected Wi-Fi network, and you should see an option like Share or QR Code.
Step 3: You can either scan the QR code or view the password if it's available.
For iOS (iPhone/iPad)
Go to Settings, tap on Wi-Fi, and find the network you're connected to.
Tap the ‘i’ icon next to the network name and select Password.
You may need to authenticate with Face ID, Touch ID, or your Apple ID password.
Once authenticated, your Wi-Fi password will be displayed.
Troubleshooting and Tips
If you run into issues, here are a few things that can help.
Can't Find the Key?
If you're stuck and can't access the router settings or Keychain Access, there’s a fix! You can always reset your router to its default settings. This will wipe the current settings and restore the original Wi-Fi password (it’s usually on a sticker on the router). Just remember, resetting might also mean you have to reconfigure your network settings, so be prepared.
Consider Using a Password Manager
Struggling to remember all those passwords? A password manager can be your best friend! By securely saving your network security key and other important passwords, you can easily access them whenever you need. No more scrambling to find the right one—just open your password manager, and voila!
Conclusion
So, whether you're a Windows wizard, a macOS pro, or a router reset enthusiast, finding your network security key is a breeze once you know where to look. We've covered all the steps—whether it's through your system settings, Keychain Access, or router admin panel—and each method is pretty straightforward as long as you follow the proper steps. With a little patience, you'll have your Wi-Fi password in no time!
