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. First, access and log into your home router as administrator. Menu systems vary between router brands, but most show your network SSID and network security key on the main page. 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. 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. 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. 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. 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. Access your iPhone Settings menu, tap iCloud, and tap on Keychain. This enables the keychain feature. Go back to the Settings menu and enable Personal Hotspot. On your Mac, connect to your iPhone's Personal Hotpot. Press the CMD and Space keys on your Mac to open the Searchlight utility. In the search field, type keychain access and press Enter. Type the name of your Wi-Fi network (the SSID), then double click on the SSID. Select the Show Password checkbox. You may need to type your Mac's admin password to allow the password to be displayed. Find the Network Security Key On Windows The easiest way to find your Wi-Fi password is if you've already connected to the network with your Windows 10 PC. Click the Start menu, and type Network Status. Select the Network status system settings utility. In the Network Status window, select Change adapter options. In the Network Connections window, right click on the active Wi-Fi network adapter and select Status. In the Wi-Fi Status window, select Wireless Properties. This will open the Wireless Network Properties window. Select the Security tab, and enable the Show characters checkbox under the Network security key field. This will reveal the network security key for your wireless network. 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. Select Go and select Utilities, then select Keychain Access. Select login, and scroll through the list of network connections to find your active network. If you don't see the active network, select System and find the active network there. On Mac OS X systems older than version 10.6.x, in the Keychains window, select All Items. Scroll through the list of network connections to find your active network. Under Name, select the Network Name for your active network. Under the Attributes tab, select the checkbox next to Show password. You will need to enter your Mac Administrator or Keychain password to see the network password. Enter it and select OK. You can find the network password in the Show password field. 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.
