Recent Plasma Desktop lets you show a network QR code right from the right-click context menu.

Can I also put my networks with Emoji SSIDs into the QR code?

Yes, I've been doing this for years with QR codes for WiFi.

Works for emoji in both the SSID and Password.

My last phone, LG Nexus 5X, couldn't do this. My current phone, Unihertz Jelly 2, also can't do this. Guess I have to buy the "premium" brand Androids for this feature.

You're not missing out. My moto g power (2020) can sometimes manage the feature, but only sometimes. Sometimes it just won't scan with the regular camera and you've got to open a dedicated qr scanner... So you're really better off starting with the dedicated qr scanner... except I have a button on the home screen for the camera and have to dig for the dedicated app.

I have the same model - amazing phone for the price btw. - and have the same intermittent issue. But, I can switch to Lens which will always work - just not as seamlessly.

That is actually quite cool. I wonder how many command line tools could take advantage of such a feature. Like, I don't know, upload a file somewhere and show a one-time QR code to transfer that file into your phone or something.

This 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…

In the suburban/rural southeast US I see lots of QR codes and lots of old people using them. Especially since 2020

"oh, I have to get up from my table, carry my laptop over to your fridge and attempt to type in the password without dropping anything?" (I have a horrible short term memory and struggle with short phrases)

You don’t talk like this when you are invited somewhere? You do ?

I internally think this every time I bring my laptop to a cafe and the barista points at a 'cute' wifi password sign (or bathroom unlock code).

Vistor: Ok, I took a picture of it. Now what? Do I send it to you? Me: Is it doing anything? What did you do? Vistor: No. I pointed my phone at it like you said. Then I took a picture. Me: What app are you using? Visitor: The photo app I always use. Me: Can you be more specific? Visitor (showing where the icon is): That one. I always use it. Me: That one sucks. Do you have any others? Visitor: I don't know. There's p…

Has this really happened to you? I got the WiFi QR printed and hanged in my living room, and to this day nobody has ever had a problem. QR might seem too techie, but they are so pervasive that everyone knows how to use them.

> but they are so pervasive that everyone knows how to use them.

Nope. I know people first-hand who don't. Hell, even I don't know how the average person does it. My own phone's camera app doesn't detect them so I had to find a random 3rd party app and trust that it's not stealing the info. In fact I'm not sure I've ever used the stock camera app on any phone to scan a QR code before. For some folks it might be "press Camera and scan", but for others it's way harder than it looks.
