What Is a Network Security Key and How Do You Find It?

Everything you need to know to find and use your network security key

A network security key is a code or passphrase that lets you connect your computer or mobile device to a private network.

What Is a Network Security Key?

Every secured network will have a network security key, but not every network uses the same kind of security.

  • WEP (Wired Equivalent Privacy): Encrypts data between clients using a static encryption code.
  • WPA (Wi-Fi Protected Access): Uses a unique "packet-mixing" function and integrity checks.
  • WPA2 (Wi-Fi Protected Access 2): Uses a security protocol with pre-shared key (PSK) authentication. In the case of enterprise users, WPA2 uses an enterprise authentication server. 

You can check which security method is currently enabled, and find your network security key, by accessing your router.

How Do You Find Your Network Security Key? 

The easiest way to find your network security key is through your router directly.

  1. First, access and log into your home router as administrator.

  2. Menu systems vary between router brands, but most show your network SSID and network security key on the main page.

  3. If it isn't displayed on the main screen, you can find the Wi-Fi password by finding Connection or Wi-Fi in the navigation menu. The Wi-Fi connection settings screen shows you the network security key.

  4. If you have access to the router, it's the fastest and easiest way to find the passphrase or encryption key.

Find the Network Security Key On Your Phone

If you want to save time, you can view the stored network security key on your Android or iPhone.

On Android

There are several ways to locate the saved network security key on your Android.

  1. Install ES File Explorer and access the Root Explorer feature. Tap Local and Device to see your device's root folder. You can access the root folder, and navigate to misc and wifi to see the Wi-Fi security key in the wpa_supplicant.conf file. This option requires root access, so it won't work for most users.

  2. Another option is to install an Android terminal emulator and issue the cat /data/misc/wifi/wpa_supplicant.conf command to view the file contents and see the network security key. Again, root access is required.

  3. The best option without root is to install and connect Minimal ADB and Fastboot on your PC. Once you're connected to your Android, you can access and view the contents of the wpa_supplicant.conf file to see your stored Wi-Fi password.

On iPhone or iPad

Finding your stored network security key on an iPhone is much easier, and doesn't require root access.

  1. Access your iPhone Settings menu, tap iCloud, and tap on Keychain. This enables the keychain feature.

  2. Go back to the Settings menu and enable Personal Hotspot.

  2. In the Network Status window, select Change adapter options.

Find the Network Security Key On Your Mac

Accessing the password for your network on your Mac is just as simple. On Mac, the network key is located in Keychain Access.

Here's how you can find it.

  1. Select Go and select Utilities, then select Keychain Access.

Keep Your Wi-Fi Password Safe

It's very easy to find your network security key from any device connected to your network. Most people do this to give the password to visitors. However, a more secure option is to create a guest wireless network for that purpose.
