WiFi networks are incredibly commonplace in our modern world. We expect networks to be available in hotels, restaurants, and even trains. But most of the time, these networks are well protected with extremely long passwords. It’s okay when only one person wants to use the network, but what do you do when many are to use the network on their own devices?
Smartphones are pretty good QR code readers. All you need is a camera and application capable of decoding the message. XDA Senior Member Stevenator21 created an application to generate a QR code for your currently connected wireless network, which can be easily shared with your friends. You might wonder about WPS, but not every device supports this technology.
The QR code generated by WiFiQR can be shared with other devices, so the result might be printed or displayed on a screen. In future releases, the developer plans to add an option to show the QR code of networks stored on the device in addition to the corrently connected network—hopefully with password already enabled. Of course, you can type the password manually.
