Show HN: Print a WiFi Login Card

&gt; Your WiFi information is never sent to the server.<p>This makes me think that we could use some flag that identifies purely static websites. Like next to the green https lock there is a sign that this website can not send data to any server

I can also recommend drawing it instead of printing if you hate printers with the same passion as me. Record to beat for drawing a working QR code is 3 tries and I think about three hours (for an SSID of 13 bytes (5 unicode characters) and 19-character password). I did it mostly out of curiosity how hard it would actually be (spoiler: medium difficulty).

I do wish there was an option to safely disable all connectivity in a browser tab (forever) like with Javascript or camera access.<p>Yes, saving the page, disconnecting your network connection, then deleting the page would work, but it&#x27;s a real bother.

My iPhone has a pre-defined &quot;Make QR Code&quot; &quot;Starter Shortcut&quot; that you can invoke by typing &quot;Make QR Code&quot; in Home screen search. It basically generates a QR code of the same WIFI:S:$SSID;P:$PASSWORD;; format as wificard.io.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;QR_code#Joining_a_Wi%E2%80%91Fi_network" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;QR_code#Joining_a_Wi%E2%80%91F...</a>

<p><pre><code> qrencode -t utf8 &#x27;WIFI:T:WPA;S:network;P:password;;&#x27;</code></pre>

I know it says &quot;No tracking, analytics, or fingerprinting are used on this website&quot; but it calls out to Google fonts...

I just generate a QR code for my wifi login using libreoffice writer.<p>Edit: just use the built in QR code generator with a string in this format.<p>WIFI:T:WPA;S:$SSID;P:$PASSWORD

This is a nice idea! I once whipped up a shell script to do the same thing.<p>UX feedback - disable autocorrections on the input fields [1], you may want to trim white space as well.<p>[1] <a href="https:&#x2F;&#x2F;davidwalsh.name&#x2F;disable-autocorrect" rel="nofollow">https:&#x2F;&#x2F;davidwalsh.name&#x2F;disable-autocorrect</a>

Shameless (mostly) plug here, <a href="https:&#x2F;&#x2F;github.com&#x2F;kmanc&#x2F;wifi_qr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;kmanc&#x2F;wifi_qr</a>.<p>This repo of mine walks through how to use a raspberry pi with an eInk screen to automatically update passwords and the resulting QR code. Would love to see what y&#x27;all think!

iOS share password functionality has really simplified things for guests. This is a neat idea for an AirBNB or similar short term rentals.

Asking as a person who understands the fundamentals of all of the technologies involved but is horrified by much of what goes on in the minds of today&#x27;s web developers and designers, what motivates the decision to make this repo use make, docker, yarn, npx, nginx, react, and jest rather than a bit of static HTML and css and something like qrjs2.js or VanillaQR.js with a simple canvas or datauri update in onInput?

I got a QR code like this on the wall with the SSID and the password written on the paper as well as a NFC tag with the wifi credentials between the paper and the wall.<p>I think nobody ever has scanned the QR code.

Really neat! I whipped up a single file HTML version [1] with a demo [2] using only a CDN-hosted QR library. Thanks for the distraction!<p>[1] <a href="https:&#x2F;&#x2F;gist.github.com&#x2F;ianobermiller&#x2F;9f17f1022bc75c2228d742d97fe1f82d" rel="nofollow">https:&#x2F;&#x2F;gist.github.com&#x2F;ianobermiller&#x2F;9f17f1022bc75c2228d742...</a><p>[2] <a href="https:&#x2F;&#x2F;bl.ocks.org&#x2F;ianobermiller&#x2F;raw&#x2F;9f17f1022bc75c2228d742d97fe1f82d&#x2F;" rel="nofollow">https:&#x2F;&#x2F;bl.ocks.org&#x2F;ianobermiller&#x2F;raw&#x2F;9f17f1022bc75c2228d742...</a>

I am sure that this is not what this site is for. But...<p>For a moment I thought: What a great attack vector. Collect WiFi passwords from around the globe.

This can be done locally in the browser with qifi: <a href="https:&#x2F;&#x2F;github.com&#x2F;evgeni&#x2F;qifi" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;evgeni&#x2F;qifi</a>

A nice, friction reducing optimization for a home user.<p>Great work, OP. I&#x27;ll be printing one for my fridge later today.

This is cool. I whipped up a quick clone on CodePen using Shoelace web components for fun: <a href="https:&#x2F;&#x2F;codepen.io&#x2F;claviska&#x2F;pen&#x2F;NWjbdoK" rel="nofollow">https:&#x2F;&#x2F;codepen.io&#x2F;claviska&#x2F;pen&#x2F;NWjbdoK</a>

Looks like a great way to farm a list of commonly used passwords for users or just wifis.<p>I never trust anything online that generates anything with a password. I got burned from a crypto wallet scam once. but fool be twice...!!!

Love the source code, so clean. First time I see a makefile used like that with Docker and front commands.

Very cool and nicely executed! Love it

Can you actually point your phone camera at a QR code and have it connect automatically, as the website says? I generally avoid QR codes as they obfuscate the target URL, but I thought you needed an app for reading them on Android and possibly also iOS.

The format is:<p>WIFI:S:&lt;SSID&gt;;T:&lt;WPA|WPA3|WEP&gt;;P:&lt;password&gt;;;<p>And can be generated with any qrencode program.

Really cool, despite that some comments show that generating such QR codes can be done with a simple command; because using this service is faster for me as a person who is not familiar with QRs.

This is probably safe, but I really can&#x27;t bring myself to do it.

The magic here is that there&#x27;s a WiFi URL scheme. I never knew. Don&#x27;t know how well supported it is on old OSs but it&#x27;s pretty cool:<p>wifi: &#x2F;&#x2F; [username] : [password] @ ssid

I am not sure I understand the app. Is it 2 input fields one for name and one for password? Which you then print? Is that the functionality - or have I misunderstood?

So apparently navigating to a URL similar to this on iPhone connects you to the specified wifi [0]:<p><pre><code> WIFI:T:WPA;S:${ssid};P:${password};; </code></pre> [0] <a href="https:&#x2F;&#x2F;github.com&#x2F;bndw&#x2F;wifi-card&#x2F;blob&#x2F;master&#x2F;src&#x2F;components&#x2F;Card.js#L45" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bndw&#x2F;wifi-card&#x2F;blob&#x2F;master&#x2F;src&#x2F;components...</a>

On ios it works fine with the default camera app, but what about android? I&#x27;d guess support varies depending on vendor?

&quot;Tape it to the fridge&quot; Please don&#x27;t do this, at least keep it hidden from general viewing.

I almost gave my SSID and password over to this guy, that&#x27;s an interesting fishing technique.

Hey I almost gave my ssid and pw over to this guy. That&#x27;s an interesting phishing technique

A nice addition would be either (1) support other languages or (2 - simpler) the ability to edit the field titles (e.g. change from &quot;Network name&quot; to &quot;Nome da rede&quot;).

You can also set up an NFC tag for WiFi. It works basically the same but saves with fiddling with your QR reader, just tap the phone to the tag and click connect.

Just a FYI&#x2F;PSA: Fritz!Box routers by AVM do have that option right in their WiFi-settings page...<p>Also, there are lots of offline QR generator apps...

At first I was like &quot;OMG, this is going to be awesome, this person has a QR generator which will magically connect me to the WiFi with my password embedded in the QR somehow. I am going to have to read the source... This is gonna be great... but then, disappointment. It is just a card with my password in plain text. Why the heck would I ever print this out?

more QR meh -- how does one use this? Assuming everyone has native QR code ability that ties into Network setups? Sorry if I&#x27;m behind but is this standard in Android now? (who cares about iOS, let&#x27;s go with broader platform for now)

How convenient I asked myself this question about five hours ago!<p>There are chances out there, unbelievable.

Why would you trust a random page on the internet and go paste your wifi password on it?

On Android just go to Settings &gt; Wifi &gt; SSID &gt; Share<p>From there its up to you how you print.

Cool! I wonder if we can generate QR code for WPA2 Enterprise with EAP-TLS?

No password on my farm.<p>Why bother setting a password in a non-crowded area?

for this to work device-agnostically presumably there is a URL scheme such as &quot;wifi:&#x2F;&#x2F;&quot;, can anyone confirm?

This is a ridiculously good idea. Thank you.

The Shortcuts app on iPhone can do this.

I never had of cards how do you get it

Cool app, dude. Thanks for sharing.

This is really cool! Good work!

Thank you for this!

Nice try, lol. People, never enter your passwords on such pages.

Relevant xkcd: <a href="https:&#x2F;&#x2F;xkcd.com&#x2F;792&#x2F;" rel="nofollow">https:&#x2F;&#x2F;xkcd.com&#x2F;792&#x2F;</a>

This looks like a simple WiFi password generator, a cooler solution would be to generate one-time passwords for guests. When someone comes to you, they can click on the touch display to generate a password, each guest can then have a separate VLAN.

Neat. Works with Unicode!<p>Feature request: giant passwords like that one that was posted on the side of a building.<p>I ran it with network off and saw the code, so it looks safe.

I&#x27;m here for the top comment.
