You're in the midst of a groggy fever-dream while waiting for your delayed flight, struggling to pass the time while inexplicably sipping down on multiple coffees.

Naturally, you turn to the universal safe-haven of free Wi-Fi to pull yourself up from the dark hole. Maybe you'll watch some YouTube, or maybe you'll go on a tour through Google Street View.

All seems to be looking up until you're met with the inevitable password prompt, threatening to spoil your fun before you fail to guess the code numerous times.

Well, thanks to a new map created by travel blogger and computer security engineer Anil Polat, this whole scenario just got a whole lot easier to navigate.

The map, which Polat updates regularly, includes the Wi-Fi passwords and locations of dozens of airports around the world.

Need relief after a rough weekend away in Prague? There's a password for that.

Catching up with the world after a spot of travelling in Kenya? You better believe there's a password for that.

By clicking on an airport, users receive tips and directions on where to sit to access the Wi-Fi, along with instructions for inputting the password. Sometimes you'll require a certain departure lounge, while sometimes you'll even have to be armed with the date.

So, along with waving a goodbye to a place you prefer to your home, you can now bury any potential additional charges. Just remember to use this omnipotent power wisely, and always for good.
