Did something similar for my roommates recently. We have no printer in our flat, so I grabbed a piece of graph paper, redrew the QR code and taped it onto the fridge. Now our guests can simply scan the picture instead of strenuously rewriting the complicated password.

What's the problem with using a long but humanly readable password, like several concatenated words? It's not like you are trying to protect against large scale attacks.

Scanning it is easier than typing it into your phone.

Every tesla car has a sim card and data connection that is used to connect to a vpn that high enough level engineers can use to run ssh commands directly on every tesla car at once or even target certain ones. You know nothing john snow.

California is thankfully neutering that sort of backdoor access.

Really? Neutering it how?

Tesla already has a “Allow remote access” toggle, which defaults to OFF, that prevents you from connecting to it via the app etc.

(Whether this fully prevents Tesla connecting to it remotely, I’m not so sure...)

Most 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…

>All legal documents and forms should have one.

The ones you download from e-government in Turkey have QR codes. I think other e-documents have QR code too. You can validate them by using https://play.google.com/store/apps/details?id=tr.gov.turkiye...

Seems like the obvious thing would be to have the QR code contain a "receipt ID" (UUID?) in a URL. When the QR code is scanned, the browser opens to the URL, the remote side takes your "receipt ID", and presents you with a list of all the items you purchased. I can't imagine any decent-sized retailer isn't already maintaining records like this.

See, one of the useful properties of a paper receipt is that, once you receive it, you can be fairly confident about the ~one way you're going to lose it

Two ways. Receipts fade, sometimes very quickly.

Or when you setup a new apple computer, you have to enter the wifi password without being able to see what you type, without being sure it is the right casing, and if you are not in the US without being sure you are using the right keyboard layout in the first place (the is no opportunity to type something else in a clear text box before that step).

When a friend tried to connect to a new network on their MacBook, a second friend with an iPad got a pop-up that such-and-such was attempting to connect to their network, and if they wanted to share connection details. One click and they were in. Creepy, but convenient.

I don't buy iPhones but if Apple produces ADSL modems and splitters I am definatly going to buy.

Remember bitly, AMP, CDNs? Also, as to something like a javascript exploit in a URL itself, QRs can hold a surprising amount of data, enough to max out most URL browser limits around 2,048 bytes.

You've described some of the scenarios that would result in me not clicking the link. The feature works well, doesn't it. This is functionally the same as hovering over links in emails, which is the context in which I made my comment.

Ok, explain those to my mom.

I have an old Kindle it would be fun to put the QR code on that. And maybe somehow a script that rotates the password updating the Kindle.

I setup a raspberry pi with a small display showing the weather forecast, next 5 calendar events and a QR code for the WIFI using this:

https://github.com/TeraTech/MMM-WiFiPassword

weather:

https://github.com/jclarke0000/MMM-DarkSkyForecast

Sits on the kitchen counter. Guest password is rotated and the display is auto-updated.

The raspberrypi is running MagicMirror, but I just have it outputting to a small display (7"). Looks great.

I use a Ubiquiti wifi AP and it has an API to change the guest password.

I 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.

Which devices support this?
