Reading a long WiFi password to every guest gets old fast. A WiFi QR code fixes that: print it once, and people join by pointing their camera at it. Here is how to make one and where to put it.
TL;DR — Open the WiFi QR code generator, type your network name and password, pick the security type, then download a PNG or SVG to print. Guests scan with their camera and tap to join.
What goes into the code
A WiFi QR code holds three things: the network name (SSID), the password, and the security type. Get the security type right — for almost every modern router that is WPA/WPA2/WPA3. Pick WEP only for old equipment, and “no password” for a genuinely open network.
If your network name does not broadcast, turn on the hidden network option. Without that flag, a phone will not look for a non-broadcast SSID and the scan appears to do nothing.
Where to put it
Think about who can see the code, because anyone who scans it can read the password. Good spots are a table tent in a café, a card in a guest room, or a fridge magnet at home. Avoid taping it to a window facing the street if that same network also reaches your work laptop or smart-home devices.
For anything more sensitive, put guests on a separate guest network and make the QR code for that one. Then a scanned password only ever grants guest access.
Make it look intentional
The code does not have to be plain black squares. You can match it to a venue’s colors and drop a small logo in the center, as long as you keep strong contrast between the code and its background. Test the styled version with a couple of phones before you print a hundred copies.
Make one now
The WiFi QR code generator builds the code in your browser — your password is never uploaded. Enter the details, style it if you like, and download a sharp PNG or a print-ready SVG.
