How to Hack Wi-Fi Passwords on your any smartphone or computer Your intensions when cracking a Wi-Fi password are no doubt noble—we trust you—so here's how to do it. Chances are you have a Wi-Fi network at home, or live close to one (or more) that tantalizingly pops up in a list whenever you boot up the laptop. The problem is, if there's a lock next to the network name (AKA the SSID, or service set identifier), that indicates security is activated.
