How to make a Wi-Fi QR code

Type the network name exactly as it appears when you look for it on a phone, pick how it is secured, and enter the password. The card appears as you type. Download it, print it, and put it where guests sit.

Scan it once yourself before it goes on the wall. Joining your own network from the printed card is the only check worth doing.

Where do I find the network name and password?

On most routers both are printed on a label underneath it, next to the words SSID or Network name and Wi-Fi password or Key. If somebody changed them, they are in the router's settings page, usually under Wireless.

The name has to match exactly, including capital letters and spaces. A code made for Cafe Noor will not join cafe noor.

WPA, WPA2 or WPA3?

Pick whichever your router says it uses. All three produce the same kind of code: phones have agreed on one marker for WPA-family networks, and a code that claims to be WPA3 specifically is a code most cameras ignore. Choosing WPA3 here still makes a card that works.

WEP is older and far weaker. It is offered because some equipment still runs it, not because it is a good idea.

What about an office login?

Networks where each person signs in with their own username — the kind an office or a university runs — cannot be put in a QR code that phones will accept. There is a format for it, and no two phones read it the same way. A code that connects nobody is worse than no code, so this tool says so instead of making one.

Should the password be printed on the card?

That is why there are two kinds of design. A guest card prints it: the guest whose camera will not scan can still type it in, and your staff stop being asked. A scan-only card prints no readable password, which is the right choice for a window, a shared wall, or anywhere the card can be read by people who are not your guests.

Either way the password is inside the code itself. Anyone who can scan the card can join the network — a QR code is a convenience, not a lock.

Printing it

Print at A5 or larger and leave the white border around the code alone; it is part of the code, not margin. Matte paper or lamination beats glossy, which throws the flash back at the camera. A card about 10 cm wide scans from across a table.

Does it expire?

No. The code contains your network name and password, so it keeps working until you change the password. When you do, make a new card — the old one will not tell anybody it is out of date, it will simply fail to connect.
