I once had an idea to generate "hidden" qr codes in art and photos. Initially I wanted to take a photo of a giraffe and replace one of its spots with a QR code, and hang it in my living room for guests to scan. It turned into this (broken) website: https://www.qraffe.com/. I don't have a lot of time right now to fix it. The pdf rendering is broken. If anyone likes this idea and wants to help with a PR, I'll be mighty appreciative. https://github.com/joeframbach/qraffe

Re: Guest WiFi using a QR code
#84This is super cool and would be awesome for situations where your guests are familiar with QR codes. But from my experience the process would go something like this: Visitor: What's your wifi password? Me: No password needed! We have a cool QR code you can scan that will auto-join you! Visitor: Oh cool, how do I use a QR code? Do I need an app? Me: Nope, just point your camera at it. Visitor: Like .. .take a picture…
I agree with scenario one but also think you went too simplistic on the second scenario. Even with a simple wifi password like you suggested, you still need to specify the uppercase letters and plenty of people might have trouble spelling tortoise correctly on the first try.
Nevermind the fact that my friends group tends to be about 50% passwords of the type you used and the other 50% of them use a randomly generated one from a pw generator or add enough random capitalization of things like family member names to make it awkward. More often than not, I end up handing them my device to type it themselves.
The QR code seems a much simpler solution once people know how to use them. Thanks to things like electronic menus at restaurants due to Covid more folks than you might realize actually do know what to do. If grandma can learn how to use a QR code to access the high school band concert program online (true story), then anyone can.

That might have been the case a few years ago (at least here in BC, Canada) but these days virtually every sit-down restaurant I go to has their menu available - often exclusively - via QR code.

Visitor: what's your wifi password?
Me: it's the entire alphabet in order.
Visitor: I don't want to type 20+ obnoxious letters.
Me: can I interest you in a QR code?
Re: Guest WiFi using a QR code
#87Here'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.
That seems fine until someone's compromised device joins your network, sniffs for open ports, and starts uploading or ransomware-encrypting your NAS.

#88I do this and it's great. Everyone enjoys scanning it and doesn't have to fiddle with the credential entry.

#89Earlier quoted context omitted.
Lol that's awesome EDIT - I had an idea that I'm currently working through that I like but am a little stuck so taking a break before I revisit. TLDR is to use an ATTINY85 to auto-"type" the password in for folks who bring a laptop and can't scan the QR code. I wrote the Python code to generate the .ino script that would actually do the writing, but I'm having a little bit of trouble getting micronucleus to write the…
Wouldn’t it be easier/maybe more practical to print the password to the e-ink screen as well? (QR code error correction is usually enough to let you just knock out part of it and put the text right there.)
Maybe! The problem I was trying to solve was that a 30 character password randomly generated is a pain to type out by hand haha. That said I think having the text would be a step in the right direction

#90I print wifi QR codes on wood signs and on cork coasters for Airbnb/VRBO hosts. It's a good little side business. https://www.etsy.com/shop/ligninandlight?section_id=28828952
I 3D printed a QR code puck for my house wi-fi. It's an easy demonstration of at-home fabrication that elicits some conversation, without having to hand over a password.
