InstaWifi For Android Lets You Share Your Wi-Fi Network’s Key Using QR Codes Or NFC

I am pretty sure we have all been in the position of going from one house to another, or from the house to the office and attempting to join a wireless network only to find out that no-one can remember the security password. Although it may fall under the category of being a first-world-problem, it is actually rather infuriating to have a wireless network dangled in front of your face knowing that you don’t have the security credentials to get access to it.

The InstaWifi app for Android offers one solution to that issue by allowing users to connect to and share Wi-Fi networks pretty much instantly with other people. Let’s face it, at one point or another we – probably – all needed to share our home or office wireless network details with friends or family members only to be flummoxed by not being able to find the flimsy piece of paper that has the code written on it. Or even worse still, telling the enquirer to look at the bottom of the router for the passcode that was provided when the hardware was installed.


It may not be the perfect solution, but the purpose of InstaWifi is to allow users to connect and share networks with those around us using technologies available on the handset. The app makes use of either QR codes or Near Field Communication (NFC) technology to share the information of the network, allowing the receiving party to connect to it pretty much instantly. Gone are the days of handing over a scrappy piece of paper or attempting to remember if the password contains lowercase and uppercase letters.

Although it’s a pretty nifty little piece of kit, it is worth heeding the developers warnings on the Google Play Store. The QR code that is created by the device contains the password for the relevant wireless network and should therefore never be shared with random people. It is also an added bonus that no rooting is actually required to use this app, although if the device is rooted then the app will request root permissions on startup in order to capture the current Wi-Fi network and password details.
