Surely every time you have guests at home, one of them asks for the credentials to be able to use your Internet connection through their mobile, tablet or computer. If you are one of those who do not like to share your passwords, even with family, friends, etc., We suggest you do it through a QR code.
Sharing your WiFi connection through a QR code is very simple. What's more, this will allow you to always carry it with you - with a screenshot - or by printing it on paper and leaving it anywhere in the room where guests are going to connect. Of course, they must have a QR code reader downloaded to their devices - these will be somewhat more complicated if it is a laptop. However, we will continue with the explanation and create our particular QR code with the data to connect to the WiFi network of our home.
First of all, you should know that this is also viable when we want to share the internet connection generated by our smartphone — be it Android or iPhone. All you have to do is take a screenshot of the generated code and voila: every time you are asked to use your connection, show the code through the screen.
But, the important thing is to know where to generate that code with our data. Thanks to the portal iDownloadBlog, we echo the page qifi.org. Once inside you will see that you are asked to enter all the access data to your WiFi connection. In other words: you must enter the SSID —network name—, the type of encryption it uses (WEP, WPA, WPA2, etc.) and the password you use. In addition, you are instructed to check if your SSID is hidden - that when a scan of available WiFi networks is made, it does not appear in the list that is generated. If so, check the last box "Hidden". Once you enter all these data, you just have to click the "Generate" button and a QR code will be created.
If you are wondering if everything you enter through the browser is safe, the web application developer indicates that everything remains on your computer. Nothing is sent to any server. And if you don't believe his words through the text, he invites you to visit the repository at Github.
