Can you actually point your phone camera at a QR code and have it connect automatically, as the website says? I generally avoid QR codes as they obfuscate the target URL, but I thought you needed an app for reading them on Android and possibly also iOS.

Most phone cameras nowadays have a built in qr-code reader.

But does it automatically recognise it as an SSID and password and connect as the website suggests?

It’s definitely built into iOS, just point the camera app at it and it’ll tell you what the domain behind the qr is, then just touch to follow the link.

Something like wifi will have a custom prompt that says “Connect to WiFi network MyNetwork.”

I am sure that this is not what this site is for. But... For a moment I thought: What a great attack vector. Collect WiFi passwords from around the globe.

My first though was "Why would I ever enter my wifi credentials into a web form?", but perhaps there are people who would...

To be fair it’s fairly easy to check that it didn’t send any data over the wire

At first I was like "OMG, this is going to be awesome, this person has a QR generator which will magically connect me to the WiFi with my password embedded in the QR somehow. I am going to have to read the source... This is gonna be great... but then, disappointment. It is just a card with my password in plain text. Why the heck would I ever print this out?

Wifi passwords aren’t supposed to be secure. Really they’re only to keep people off the network that you want to keep, well, off the network. The current method of connecting someone to wifi is usually just telling them the password. If the guest has a computer on the network (or a mac signed into the same apple ID as an apple device on the network), it’s trivial to figure out a network password that was entered for you.

If you’re wanting a _really_ secure network, WPA2 isn’t the way to go. You’d want to credential every user using 802.1X or WPA2 Enterprise.

On iOS, you get a banner notification with the name of the wifi network, for you to tap to connect to. It does the rest from there, yes.

This has been the case for quite some time. I assume Android can do it too (and if so, probably did it first).

A lot of developers only know the new, needlessly complicated ways of doing things. I have met professional software engineers who have never heard of shared web hosting, for example. It's also surprisingly possible to learn enough about programming to get a job without understanding basic computing concepts. I've met professional software engineers, with multiple years of experience and promotions under their belt,…

No, how can you not know the difference between RAM and disk in a server context? What sort of programmers are these?

I know the different between RAM and disk in a server context (what sort of programmer wouldn't?!), but I've worked pretty exclusively in no-persisted-storage environments (mostly Heroku) for ~5 years now, where referring to "saving" files/data outside of a DB context almost exclusively means "save to memory" and I routinely run into problems whenever my stack requires downloading any sort of third-party library that would have to persist outside of RAM (e.g. downloading NLP libs).

When you abstract "storage" into "my library/tools save state somewhere" (and god forbid you include localStorage into the mix!) and don't deal with the hardware itself, I could see how a lot of new-ish coders wouldn't be able to differentiate RAM and disk.

Why would you trust a random page on the internet and go paste your wifi password on it?

Is your threat model really so severe that it includes someone driving to your house and connecting to your wifi network? Of all passwords, a wifi password is one you should _never_ reuse.

You could also inspect the source, it’s open source, or network requests.
