Question

Are these generators safe to use?

Community Answer

If you mean do they keep your password secure, no. You are entering an unencrypted password that will be displayed to whoever scans the QR code. If you're wondering if they're malware/safe to use on your computer, yes, they are perfectly safe.

Question

When a device scans the code, it shows the SSID and the password together with the 'Connect' option. Is there any way to make the password invisible?

Community Answer

No, I'm afraid not. The information points within QR codes are, simply put, wide open. That is, after all, their primary purpose; the quick and simple dissemination of information. Indeed, more recent devices even automatically replicate the QR code on the phone's s screen so that others can easily scan it from your phone at a later time, long after the end of the party, BBQ, etc., where the original printed QR code was pinned up for visitors/guests.

Question

How do I ensure these generator websites do not keep the entered SSID and password?

Community Answer

The qifi.org site appears to be pure javascript, no server is needed to generate, so I recommend: 1) Visit qifi.org (don't enter anything). 2) Disconnect your computer from the internet. 3) Enter data, export results. 4) Close browser tab. 5) Reconnect computer to the internet.

Question

Has anyone checked the source to ensure that sites aren’t collecting geo data together with WiFi security information and sharing it?

Community Answer

No. Nor should it realistically matter as the websites provided are simply examples. If you are particularly paranoid about someone getting onto your WiFi then you shouldn't be giving your WiFi password out in the first place. If you are following this guide then one must assume that you are planning to set up a guest WiFi network with a guest password for guests. You could just change the password and SSID after an event. Alternatively, you can generate your own QR code with offline software by constructing an appropriate string according to the specification (linked on page recommended by the article).
