Once you connect to a Wi-Fi network you probably never have to think about that password again, because once you're connected, you're connected. However, maybe a friend and family member comes over to your home and asks if they can connect to your network. Ah, what was that pesky password again? Is it that super long number on the back of your router? Or did you change it to something more personal?
Lucky for you, there's a way to find all your Wi-Fi passwords in a single place. Just check your computer.
