Having to spend long hours in an airport without internet access is one of the worst traveling experiences. Luckily, one clever guy came up with a solution to this problem.

Computer security engineer and travel blogger Anil Polat launched an interactive map which offers its users WI-FI passwords of networks in airports all over the world. Also, it’s really simple to use. You just have to click on a specific airport and the information about the available connections instantly pop up. Polat updates this map regularly and it already features more than 130 airports across the globe.

For those who will say that it’s useless because you need to have internet access to find the WI-FI passwords in the first place, the creator of the map also provides its downloadable offline version as well.
