Why would I want to make it EASIER for people coming over to use my WiFi?
You don’t give your WiFi password to everyone that visits?
Not OP, but I've a guest network.

#12Combine this with some automatism which changes the password of your guest WiFi and putting it on a cheap e-ink display.
Re: Encoding your WiFi access point password into a QR code
#13Most ISP put this kind of QR code on the provided "modem" in France with the default Wifi password of the device.
I love QR code. I think it should be everywhere. All legal documents and forms should have one. All supermarket bills should have one.
It's a fantastic way to transition from paper to bits.
Unfortunately most users have no idea what it is. They don't know what a URL is, so a QR code is out of the question.
Plus they don't necessarily have a QR code scanner on their devices: not all phones have one by default, most laptops definitely don't. Not to mention some QRcode readers are sometimes just the regular camera app (E.G: modern iOS), which is very confusing. And even if all that is not a problem, your QRcode scanner may not be able to understand a particular format or will read the Wifi code but just display it while it's supposed to save it as a new access point.
It's definitely not a solved problem.

#14Is it only Android 10 that can do this with scanning a qr code, or also v9?
Was wondering the same. The author didn't mention the minimum required version for Android compared to IOS, so I assumed Android must have long supported it and I always just missed it. On another note I find it quite awkward that the feature is buried in that dialog on Android. You even need to tap on the network you want to connect to when that information is already in the qr code.

On my OnePlus 6T the scan QR code button [1] is next to 'Add network' so you don't have to select the Wi-Fi network first.

#15This is super helpful for mobile devices.
But it makes rather confusing on how to connect it on an e.g. laptop without having to scan the QR code with the mobile device first. If the password is 63-char length, typing it wouldn't be 'quick'.

To the replies, it was a joke >_>
Re: Encoding your WiFi access point password into a QR code
#17I have an NFC card that contains the connection information with the QR code and plain text credentials taped to it. Even less devices support that, but when they do you don't even have to open an app. Just tap and you're in.
Re: Encoding your WiFi access point password into a QR code
#18Very neat! However, IMHO 63 characters is a bit much for the password.
”If you use lower-case, upper-case, and digits, and if you generate it truly randomly, then a 16-character password has 95 bits of entropy. That is more than sufficient.”

The default camera app on my Moto G7 (Android 9) scans QR codes. When it detects this format inside a QR it offers a 'connect to wifi' button.
