This map reveals Wi-Fi passwords at airports around the world

Is there anything more annoying than having to pay for Wi-Fi, that basic of human rights?

Anil Polat, a travel blogger and computer security engineer, is doing the world a solid by creating an interactive map - which he regularly updates - that reveals the Wi-Fi passwords of dozens of airports around the world.

Polat, who hopes to visit every country in the world, has a blog called foXoMad, which aims to help people "travel smarter." His WiFox map is updated regularly, based on verified information submitted by travelers.

It's available in iOS, Android, and Google Play.
