I obviously don’t have many folks visiting my home this year, but I do like the idea of having a handy QR code ready for guests when they do visit. QiFi.com provides the pure JS WiFi QR Code Generator tool, which securely generates a QR code in a browser that can be scanned to give a phone or other device quick access to a WiFi network without having to type in complicated SSID and key combos.
Ever wanted to create a cool QR code for your guests? But never wanted to type in your WiFi credentials into a form that submits them to a remote webserver to render the QR code? QiFi for the rescue! It will render the code in your browser, on your machine, so the WiFi stays as secure as it was before (read the code if you do not trust text on the internet :-))!
If you use the Save-button to store a code, this is still secure, as the data is stored in HTML5 localStorage and is never transmitted to the server (in contrast to cookie-based solutions).
