On my home network I have guest WiFi configured and when guests come round they need to know the password. Happily there's a way to make this trivial: WiFi QR codes. A WiFi QR code is simply a text QR code with a special format as follows:
WIFI:S:<SSID>;T:<WEP|WPA|blank>;P:<PASSWORD>;H:<true|false|blank>;;
The S sets the SSID of the network, T defines the security in use, P is the password and H whether the network is hidden or not. You can create this directly by making a text QR code or use a specialized QR code generator for WiFi networks.
The resulting QR code looks something like this:

Which when scanned with the default camera app on iOS or Android will pop up something similar to this. With one click you're connected to the network.
For a finishing touch just print out the QR code and place it in a cheap frame and any guest can scan and get online with ease.

You can do the same with NFC tags and have exactly the same cheap frame with both a QR code, NFC tag and it written out (for anyone that can't do either). I think they look quite smart.
I have one just like this I made the other day! Really convenient.
Sadly, nfc to setup WiFi is only viable on Android. It does not work on stock iOS.
NFC tags unfortunately won’t work for Wi-Fi on iOS devices. Only on android. Yes, nfc works on iOS for everything else but not (at last for now) for Wi-Fi.

I've used https://github.com/bndw/wifi-card before and enjoyed it.
No frame needed, I use my Brother QL 62mm/2.4in label printer to make stickers and scatter them through the house and my parents’ and in-laws’.
For command line types, "qrencode" will do the job for you in a few moments. You don't need a web site for something this simple.
