Create a strong password for your WiFi network.

To secure your network with WPA2, you’ll need to create a password. It’s important that you choose a unique password, with a long mix of numbers, letters and symbols so others can’t easily guess it. If you’re in a private space such as your home, it’s OK to write this password down so you can remember it, and keep it somewhere safe so you don’t lose it. You might also need it handy in case your friends come to visit and want to connect to the internet via your network. Just like you wouldn’t give a stranger a key to your house, you should only give your wifi password to people you trust.
