A WPA2 key is a type of encryption for a wireless Internet connection. You can set your own password when you first set up your router, but you need to follow certain steps. Having a secure password on your router will allow you and anyone else with the password to surf the web using your Wi-Fi connection, but no one else can. If you don’t set a password on your connection, hackers are able to get into your computer, so it’s important that you set a good password right from the start. Tips Writer Bio
