A QR code by itself is completely unreadable to a human. Can't this have the SSID / password too? All too often you see what should be simple textual data wrapped in this obtuse form which only specific machines can read. Text and a QR code can be read by everyone.

I print out a sheet with some text (including the network SSID and password) and a QR code to connect to the guest wifi using libre office writer. It has a built in qr code generator. The QR code text for a wifi password is here: https://en.m.wikipedia.org/wiki/QR_code#Joining_a_Wi%E2%80%9....

No need for any special third party tools.

I did a set of 3D printed QR codes with integrated NFC stickers used as drink coasters for a friend and myself. They're pretty neat and always a talking point.

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

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.

Don't know... Having an intruder in your home wifi seems pretty high risk to me. And I don't even live in a country with high chance to get killed upon a visit by your friendly neighbourhood SWAT team...

Here's what I do in my home: I've had the same easy-to-type WiFi password (it's a name and a four-digit year) since 2005 and I just tell my guests. It's not even a guest network. It's just my network. Free hugs in my house too.

I'd love a CLI version that just produces an image or pdf file

Such a cute idea! Definitely wouldn't work when my parents come over though

Please do not only offer qr codes. Some people might not have (working) cameras.

Or they could just be trying to connect from a laptop! Or a mobile device that doesn't understand how to parse this sort of WIFI connection code. Is this any sort of standard? Do Kindle devices support it?
