World wifi airport map

A computer security engineer and blogger, Anil Polat, has done the world a huge favor by creating an interactive map (which goes by the name of WiFox) that contains WiFi passwords to free networks in most large airports around the world.

This is what it looks like: the little plane symbols on the map indicate airports, and to the left is a list of the names of all the Wi-Fi networks and their passwords.

The service’s information is constantly being updated, with new information on new airports and cities often added — so it’s worth remembering when you next go on a trip.
