WiFox is a legitimate Android/iOS mobile app that includes indications of thousands of airport Wi-Fi networks and their passwords. The app was developed by computer security engineer Anil Polat, who first created a map of free internet and Wi-fi passwords at airports around the world. The map is available offline (when you download the appropriate Google Maps) so you dont need an Internet connection to use WiFox when youre traveling. WiFox costs just $2 and is continuously updated, including the passwords.”]
