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 pop up in a list whenever you boot up the laptop. The problem is, if there’s a lock next to the name, that indicates security for the Wi-Fi network is turned on. Without the password or passphrase, you’re not going to get access to that network, or that sweet, sweet Internet that goes with it.
Perhaps you forgot the password on your own network, or don’t have neighbors willing to share the Wi-Fi goodness. You could just go to a café and buy a latte and use the “free” Wi-Fi there. Download an app for your phone like WiFi-Map, and you’ll have a list of over 2 million hotspots with free Wi-Fi for the taking (including some passwords for locked Wi-Fi connections, if they’re shared by any of the app’s 7 million users).
But there are other ways to get back on the wireless, though some of them require such extreme patience and waiting, that café idea is going to look pretty good.
