Short answer: your network security key is your Wi-Fi password.
A network security key is the password used to connect to a Wi-Fi network. It encrypts the connection between your device and the router, preventing anyone nearby from intercepting your traffic or jumping on your wireless network without permission.
You might also see it called a Wi-Fi password, wireless password, WPA key, WPA2-PSK, or just network key. They all mean the same thing. Here's how to find your WiFi security key on any device, and what to do if you've forgotten it.
Quick Reference: Where to Find Your Network Security Key
| Device | Where to Look |
|---|---|
| Router (default key) | Sticker on back or bottom of router |
| Windows 10/11 | Settings → Network → Wi-Fi → Wireless Properties → Security tab |
| Mac | Keychain Access → search network name → Show password |
| iPhone / iPad | Settings → Wi-Fi → tap (ⓘ) next to network → Password |
| Android | Settings → Wi-Fi → tap network → Share (shows QR + password) |
| Router admin panel | 192.168.1.1 or 192.168.0.1 in browser → Wireless settings |
How to Find Your Network Security Key on Windows
There are two methods on Windows. Method 1 is easier, Method 2 works even if you're not currently connected.
Method 1: Through Settings (Windows 10 & 11)
Open Settings
Go to Network & Internet → Wi-Fi
Open Wireless Properties
Show the password
Method 2: Command Prompt
Open Command Prompt (search "cmd" in the Start menu) and run:
Replace "YourNetworkName" with your actual Wi-Fi network name. Look for Key Content in the output. That's your WiFi security key. This method works for any saved wireless network, even ones you're not currently connected to.
How to Find Your Network Security Key on a Mac
Open Keychain Access
Search for your network
View the password
On macOS Ventura and later, you can also go to System Settings → Wi-Fi, click the three dots next to your network, and select Copy Password.
How to Find Your Network Security Key on iPhone or iPad
Open Settings → Wi-Fi
Tap the info button
View the password
This feature requires iOS 16 or later. On older iPhones, you won't be able to view the saved password directly.
How to Find Your Network Security Key on Android
Open Settings → Wi-Fi
Tap your connected network
View the password
Steps vary slightly depending on your Android version and manufacturer. Samsung, Pixel, and other brands may have slightly different menu layouts.
Where Is the Network Security Key on My Router?
If you haven't changed your Wi-Fi password since setting up your router, the default network security key is printed on a sticker on the router itself, usually on the back or bottom. Look for labels like:
- Wi-Fi Password
- WPA Key or WPA2-PSK
- Wireless Key or Network Key
- Default Password
If you've changed the password and forgotten it, log into your router's admin panel by typing 192.168.1.1 or 192.168.0.1 into your browser (your router's IP may vary; check the sticker). Log in with your router's admin credentials and navigate to the Wireless or Wi-Fi settings section to view or change the password.
If you can't access the admin panel, a factory reset will restore the default network security key, but it will also reset all your other router settings, so use this as a last resort.
WPA2 vs WPA3 — What's the Difference?
When you connect to Wi-Fi, the connection is protected by a security protocol. The most common are WPA2 and WPA3. Here's what they mean:
| Protocol | Security Level | Notes |
|---|---|---|
| WEP | Insecure (avoid) | Outdated, crackable in minutes |
| WPA | Weak | Old standard, largely replaced |
| WPA2 | Good | Current standard, fine with a strong password |
| WPA3 | Best | Latest standard, stronger encryption, recommended |
For home users, WPA2 with a strong, unique password is sufficient. For businesses, WPA3 is recommended where hardware supports it. If your router is showing WEP or WPA (original), it's time to upgrade.

How to Keep Your Wireless Network Secure
Finding your network security key is one thing. Making sure it's actually secure is another. A few practices that matter:
- Use a strong, unique password. At least 12 characters, mixing letters, numbers, and symbols. Avoid dictionary words or anything easy to guess.
- Change the default password. Routers ship with default passwords that are publicly known or easily guessable. Change yours if you haven't.
- Use WPA3 if your router supports it. Check your router settings; if WPA3 is available, enable it.
- Separate guest and business networks. If you have a home office or business, never put guests on the same wireless network as your work devices.
- Keep your router firmware updated. Router manufacturers release security updates. Check for firmware updates in your router's admin panel every few months.
- Disable WPS. Wi-Fi Protected Setup is a convenience feature with known security vulnerabilities. Disable it in your router settings.
Common Questions

What is the difference between WPA2 and WPA3?
WPA3 is the newer, more secure Wi-Fi encryption standard. WPA2 is still widely used and secure with a strong password. Both are fine for most home users. Businesses should use WPA3 where available. Avoid WEP and original WPA; they're outdated and insecure.
