Do you know your network security key? More commonly referred to as a Wi-Fi password, this login information keeps your personal internet connection secure. When you install a router in your home, the Wi-Fi signal can be picked up by anyone in the area, so a strong network key is the way to control who can access it.

There are three types of network keys. One of these will almost certainly be used to protect your home router:
When your network is installed, it will be protected by a complex string of randomized numbers and letters. Like most strong passwords, it can be easy to forget.
If you want to find out what your network key is or change it, here’s what you need to know.
If you have it on hand, you can look at your router itself. The password should be somewhere on its exterior, often printed on a small sticker. If the password isn’t visible on the router itself, check the box it came in or the manual that accompanied it.
To give the password to someone else, you can direct them to do the same, but it’s quite common to store your router somewhere out of the way where you won’t notice it. You don’t really want your visitor having to crawl behind the couch to find it.
There’s a better way. If your computer is already on the Wi-Fi, it will have the network key saved. That allows it to connect automatically as soon as it’s in range, and it also means you can find the information through your device.
The first thing that might trip you up is the terminology. Each ISP and manufacturer will use slightly different phrasing, so even if you find the sticker on your router, you might not know what you’re looking at.
If you’ve got the information in front of you, you’re probably going to see one of these:
Once you’ve found the router and identified the network key on the hardware, you can connect yourself and others right away.
If you’re unable to find the network key for any reason, but you have a computer connected to the Wi-Fi already, it’s a simple process to access the saved login data. For Windows 10 users, there are seven easy steps.
For anyone using a Mac, it’s a similar process. As long as you know the name of your Wi-Fi network, this should take less than a minute.
If you want to find your network security key on your computer, whether it’s Windows or iOS, you only need to be connected to the network. Even if there’s no actual internet connection, you will still be able to find the network security key by following the instructions listed above. If your computer is not connecting, you will just have to get under the couch, find your router, and look for the key there.
When your router is switched on, the default password will likely be a random collection of characters. It won’t be easy to remember, but you can actually change your Wi-Fi password yourself. It’s a relatively simple procedure, but one that will be essential if you think your network key might be compromised. Keeping your home Wi-Fi protected can prevent Wi-Fi eavesdropping and other hacks, so regularly changing your password will always improve safety.
A mismatch error is a common problem when connecting with your network security key for the first time. It can even occur after you’ve connected. There are three likely reasons for this problem.
Your device is incompatible
If you’re logging on for the first time and you're getting a mismatch error, it may be because your phone or laptop is out of date. Routers update and evolve like any other technology, and in the world of smart hardware and connected devices, it’s not uncommon for incompatibility issues to arise. Hopefully, this issue can be resolved by updating your device, or at least its network drivers. If not, you may have to contact your router's or devices' manufacturer tech support.
Your password is wrong
The most likely answer is that you’ve typed in the wrong password; we’ve all done it. Network keys are usually quite dense collections of numbers and letters, so it’s easy to miss one digit or character.
Most login details will be case-sensitive, so make sure you’re getting all upper- and lowercase letters in the right places. It can also be useful to type out your password in a note or word processing app so that you can see the text more clearly.
The router has crashed
Even if your device is up-to-date and your password is correct, you can still get an error of network security key mismatch if the router has crashed. This happens more than you’d think and will usually be flagged up by a flashing or unusual light on the router itself.
The best way to fix this is also the simplest. It’s a cliche for a reason: turning your router off and on again will probably resolve the issue.
