Making an online wifi QR code generator seems like a nifty way to make a good password dictionary. Just saying.

The one featured seems fairly legit, I believe it pre-dates the wifi spec.

I've done this for years, quite convenient. I also have an NFC tag with the WiFi which works quicker (no need to open a QR scanner and no need to focus on the image for a sec) but I'm not sure if iOS supports it. I've put the tag behind the wifi "frame" so that you can just tap it instead of scanning it. Android also has the option to "share" wifi via a QR code from the WiFi settings menu. It is quick and much easier…

iOS lets you share wifi passwords with someone else around you if they are trying to connect. I _think_ it uses your AirDrop privacy settings so for most reasonable people it would only work for people in their contact list.

I've suggested this to every AirBnB I have stayed in. Sadly I am up to about 75-100 of them and have come across this a grand total of zero times.

Yeah we use this for our AirBnB, print a page and put it in the guest book. Super convenient and clients like it.

Call me paranoid, but I've taken to not scanning "public" QR codes any longer [1]. [1] https://www.washingtonpost.com/technology/2021/10/07/are-qr-...

There is way too much human interest to that article and way too little substance on the problems. Tl;dr - there’s no security risk unique to QR codes are that aren’t simply present on the Internet at-large.

What do you need, to produce (or rather program) nfc tags...? I guess they don't have usb ports, lol.

That's a great idea! Of course, it has potential security issues; but no more than your standard sign in a store or boardroom.

The risk is small if you isolate clients from everything on LAN and limit bandwidth.

For Wi-Fi though? Seems relatively low risk to me. Concerns over password security can be mitigated by those that care by using unique, randomly-generates strings per service.

Bit of a self-plug I know, but this reminds me of something I had made a while back (https://github.com/kmanc/wifi_qr). Nice work! Always fun to see others' take on neat projects
