Whether you’re catching up with your family and friends after a year of travelling, submitting a very important report, or just want to update your Instagram, everyone needs a decent Wi-Fi signal when travelling, especially while waiting for boarding. But when your flight got delayed, you got stuck in the airport and so bored, it’s annoying when the connection requires a password or charges you for using it, and using your own data could be utterly wasteful.

So what should you do the next time you find yourselves sitting in the airport and needing a connection so bad? Just pull this amazing handy map called WiFox that contains the network and password details of the very terminal you’re lounging at.

Fortunately, the genius computer security engineer and travel blogger Anil Polat has came up with something after compiling the Wi-Fi information at different airports across the world and plugging the data into this handy interactive map. He gets the passwords for various airports and lounge Wi-Fi networks partly using tips from other travelers around the globe.

Polat adds information on the list and shares it on his Facebook page whenever there’s a new password shared. Luckily, he also makes it easy for mobiles; just download the app on App Store, Google Play, and Amazon.

Awesome right? So whenever you got stuck in an airport, just remember Polat’s map and enjoy surfing the net.
