What is a Network Security Key

The network security key is better known as the Wifi or Wireless network password. This is the password that you use to connect to a wireless network. Each access point or router comes with a preset network security key that you can change in the settings page of the device.

Now it’s pretty common to forget the security key of your wireless network. Most default keys are not easy to remember and you only enter them ones or twice a year.

In this article, I will explain where you can find your network security key on your router, access point or computer (if you already have a connection) and how you can change it.

Finding your Network Security Key

There are different scenarios when you are looking for the key for the wireless network. You just bought a new router or access point or you want to give another device (mobile phone or computer) access to an existing wireless network but you don’t remember you key any more.

If you have a device that is already connected to the wireless network then you can find the key in the network settings. Each device that is connected to a wireless networks stores the key so it can reconnect automatically when the network comes into range.

Finding the key on a new Router or Access Point

If you have a new router or access point then the preset wireless network key can most of the time be found on a label on the bottom or back of the device.
