If you've ever found yourself bored out of your mind at an airport and locked out of all the wifi hotspots, this app could be a godsend.
A handy Google Map created by travel blogger and computery security engineer Anil Polat reveals wifi passwords from airports all around the world and is constantly updated with tips from travellers.
As the list has grown in popularity, Polat has turned it into an app called WiFox.
By clicking on the planes on the map, you'll discover that the passwords for various airline lounges are revealed.
And if you're feeling like sharing the knowledge the next time you're travelling - send on that password.
