Like many developers, I need to connect several android phones to my Wifi. My WiFi password is 30 characters of pure entropy. As you might imagine, I absolutely hate to type that password. First, I tried to resolve this problem using Qr codes. It worked some much better, but I still had 2 problems.
I needed to find a way to store and retrieve an image with the Qr code, and very often I needed to update it. I thought that if an app could save the appropriate QR code automatically (after use it to connect), it would be really nice.
So that was the concept, and here's the result: https://play.google.com/store/apps/details?id=com.EasyWifiAccess
I hope you guys will give it a try and let me know what you think (and particularly let me know if anything breaks). I also hope you like the concept and the app!
This is a real life example:
