Your network security key is the same as a password.
It is the password used to connect your devices (PC, Phone, tablet, etc…) to the WiFi on a router or a cellular hotspot device. And that in turn connects you to your ISP’s internet connection.
When you try connecting to WiFi, you’ll see a list of names (SSIDs) to select from. These are the WiFi networks that are near you (yours and neighbors).
If you enter a incorrect password when trying to connect to a wireless network, you will get a message like “Network security key mismatch issues”.
Try the methods below to find the proper password. You are able to find your network security key even without internet connectivity.
This will work for most routers, a retail router you purchased or the one leased to you by your ISP (like AT&T, Comcast, etc..).
If you have a computer or phone, you can use it to find the network security key from the Wireless Network Properties.
Follow the below steps to view your password.
Since I am not an expert on macOS, I’ll refer you to someone more knowledgeable.

Your out of luck here, you can’t lookup WiFi passwords directly on your iPhone.
Unless your iPhone is jailbroken and you run an app that exposes the passwords for you.
But that’s probably not the case for most users. Use one of the other methods mentioned in this post.
On Android 10 or newer, you can create a QR code to connect another device to your WiFi network.
If this device is a Google Pixel phone, the password will be shown just under the QR code.
Below are the steps.
Now you have a few ways to find your network security key.
Once you have it, save it somewhere that is safe and easy for you to access. I recommend using a password manager.
I’ll be talking more about this on my next post.
