Print off a QR code for guests to join your WiFi network

&gt; Should you trust this tool with your WiFi password?<p>&gt; Of course not! You shouldn&#x27;t trust anything on the internet ever — but if it &gt; makes you feel better, I promise none of the information you enter on this page &gt; is saved anywhere.<p>I saw a theory on Reddit that you could safely use a tool like this by disconnecting from your internet before entering the information, then reconnecting after saving the QR code and having deleted it (thereby theoretically preventing your information from ever being sent to the website).<p>That sounds plausible, and the tool does seem to work while offline, but I don&#x27;t have the expertise to confidently state that this would 100% protect you. Anyone want to chime in with how hard this would make it for them to harvest your data (if they wanted to, which I&#x27;m inclined to believe they don&#x27;t, but just in terms of best practices)?

the little DSL format looks like this:<p><pre><code> WIFI:S:NETWORK-NAME;T:WEP;P:NETWORK-PASSWORD;H:false;; </code></pre> and i use the python tool `qr` to generate one: <a href="https:&#x2F;&#x2F;pypi.org&#x2F;project&#x2F;qrcode&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pypi.org&#x2F;project&#x2F;qrcode&#x2F;</a>

If you really want to overengineer things, take a look at <a href="https:&#x2F;&#x2F;kmanc.github.io&#x2F;be_my_guest&#x2F;" rel="nofollow">https:&#x2F;&#x2F;kmanc.github.io&#x2F;be_my_guest&#x2F;</a>! I only put in the effort to make this work for my own networking gear, but it could be pretty easily extended to work on other hardware :)

FYI this is a builtin feature on Android (maybe iPhone too?).<p>On Android, go to &quot;network details&quot; for a wifi that you&#x27;re logged into and click the &quot;share&quot; button and it will create a QR code for logging in.

What is this, the stone ages?<p>NFC tag is the way. <a href="https:&#x2F;&#x2F;lifehacker.com&#x2F;do-this-to-seamlessly-connect-guests-to-your-wifi-1849808406" rel="nofollow">https:&#x2F;&#x2F;lifehacker.com&#x2F;do-this-to-seamlessly-connect-guests-...</a>

Android gives you a QR code to share the network. Realistically you could just screenshot that, crop and print it out. Not have to rely on a third party QR service you aren&#x27;t sure about.

Beware of &quot;online QR code services&quot;, all of them insert some spam redirectons in the QR code. After trying a dozen founds from Google, I finally found a decent one from a german university.

My Frtzbox router will generate QR codes so I can just pint those. You could also save the QR code from Android device as an image and them print it. The same from a KDE desktop with the additional step of a screenshot of the active Window.

I reused a small CD jewel case to store the guest network WiFi QR code on the coffee table, and I also included a NFC tag with the same info that you can tap under the QR code, with a small NFC symbol carved out in the middle of the QR code (thanks to the error correction mecanism) to indicate the possibility.

Printing? In this day and age? Probably time for a weekend project with e-ink display which displays current guest wi-fi password. Or a simple LED matrix would be cheaper to build? As a bonus password is rotated on a daily basis.

This is awesome, I&#x27;ve always been to lazy to set this up and regret it every time someone is over and I have to tell them my wifi password is tacokissies456

What a delightful site! I really enjoy the writing style, and it does have a few nice tips. Kinda reminds me of that &quot;list of things you didn&#x27;t know you could do&quot; (or something like that) that was shared here a while ago.

I love the simplicity of the blog layout - is this open source I&#x27;d love to setup my blog to look similar!
