How to Make a WiFi QR Code for Guests in One Minute
Reading a WiFi password aloud — or worse, texting it — is the ritual every guest visit starts with. A QR code ends that: guests point their phone camera at a printed square and join the network without anyone spelling “capital Q, then a nine.”
Both iOS and Android support WiFi QR codes natively, so there is no app to install on either side.
What goes into the code
The code encodes a short string in the standard WIFI: format: the network name (SSID), the security type, the password, and whether the network is hidden. The WiFi QR code generator builds that string for you — including the escaping rules for passwords that contain commas, colons, or quotes — and renders the code live as you type.
Three things to get right:
- Security type. Choose WPA for any modern network (it covers WPA2 and WPA3). WEP is only for ancient hardware; pick “open network” if there is no password at all.
- Exact SSID. The name must match character-for-character, including capitalization.
- Hidden networks. If your network does not broadcast its name, tick the hidden box — phones need that hint to connect.
Print it somewhere obvious
Download the PNG at 512 pixels and print it — a fridge, a desk, a guest-room wall. Anything at least an inch square scans reliably from a normal arm’s length.
While you are at it: fix the password
If your current WiFi password is something like sunshine1, the QR code makes it easier for guests — and for anyone who photographs the code. A strong random password of 16+ characters costs you nothing (guests scan instead of typing anyway), and you can use the plain QR generator for everything else that needs encoding, from links to plain text.
The privacy angle, briefly
Your WiFi password is exactly the kind of thing you should not paste into a random website. The generator runs entirely in your browser: the credentials go straight from the form into the QR image on your screen, with no server in the middle. Check the page — the code appears even with your network cable unplugged.
