Call me paranoid, but I've taken to not scanning "public" QR codes any longer [1].

Works for Text Messages too! (=

I made a QR Code for my contact info in a VCard and set it as the home screen of my phone -- when I go to conventions it makes it really easy to connect with people.

There's a lot of cool stuff you can do with QR Codes now. Most of this stuff is 5-10 years old even, but the pandemic really helped educated people to look for QR Codes. Yay, Covid! =P

I've done something similar, but didn't like the static passwords. My guest wifi password is the current date, in YYYY-MM-DD format, it's been a great way to keep my guests (mildly) satisfied. The format changes on occasion

I started with this quite a long back, way before a separate Guest Wi-Fi was commonplace and we were OK just sharing the Wi-Fi. My ideology with guest at home was to offer Water and Wi-Fi. Guest were happy when Mobile Phone signals were bad (slow) and costly.

I've forgotten the tool used but I had a QR-Code for the guest Wi-Fi for a very long time. These days, people don't really care as the Internet speed on their phones are pretty fast enough and the cost is very cheap (India).

Is this automated or do you need to change every time Guests are expected?

I do the same thing, I had some little wooden etched boards made up with the ssid and and password on, then on the back is the qrcode for it.

Super easy to hand to a visitor that can either scan or type in.

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

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 than reading out the password to someone else.

That's a great idea!

Of course, it has potential security issues; but no more than your standard sign in a store or boardroom.
