WiFi QR code generator
Stop spelling out your WiFi password. Put the network in a code, stick it on the fridge and guests join with one scan.
Guide
How to use it
- Type your network name (SSID) exactly as it appears in the WiFi list, capitals included.
- Type the password and pick the security type. Nearly all modern routers are WPA / WPA2.
- Tick Hidden network only if your router does not broadcast the name.
- Test it: point your own phone camera at the preview and check the join prompt appears.
- Download, print and put it where guests sit. A5 by the kettle beats a password on a sticky note.
Examples
Worked examples
SSID HomeGuest, WPA, and the long password nobody wants to type. Frame the code in the hallway and visitors sort themselves out.
Print the code on the first page of the house guide. Guests connect before they have unpacked, and your reviews stop mentioning the WiFi.
A laminated card by the till with the code and the network name printed beneath it. Staff stop repeating the password forty times a day.
Method
How it works
The code contains a small standard text format (WIFI:T:WPA;S:name;P:password;;) that phone cameras recognise and hand to the WiFi settings. Your details are encoded in this page by an open source library and drawn onto the canvas, nothing is uploaded anywhere.
Because the password is inside the code, treat the printout like the password itself. For anything beyond home and small venue use, put guests on a separate guest network, which most routers can create in a minute.
FAQ
Frequently asked questions
How do guests use a WiFi QR code?
They open their phone camera, point it at the code and tap the join prompt. iPhones (iOS 11 and later) and Android phones (10 and later) handle it natively, no app needed.
Which security type should I pick?
Almost every home network today is WPA or WPA2, so pick WPA. It also works for WPA3 networks in practice. WEP exists only for very old routers, and No password is for open networks.
Does the code reveal my password?
Yes, the password is written into the code itself. Anyone who scans it can read it, so display the code only where you would happily hand the password to whoever is standing there.
Does it work with hidden networks?
Yes. Tick Hidden network and the code tells the phone to look for your SSID even though it is not broadcast.
What happens if I change my WiFi password?
The old code stops working, because the password is baked in. Come back, generate a new code and reprint it. It takes under a minute.
Is my password sent to your server?
No. The code is built entirely in your browser. Your network name and password never leave your device, which you can verify by loading this page and then going offline.
