Wifi Qr Code Generator

Typing a long WiFi password on a phone is annoying and error-prone. A WiFi QR code lets guests, customers or colleagues join your network by pointing their camera at it. iPhones (iOS 11 and later) and Android phones (Android 10 and later) recognise WiFi QR codes natively in the camera app.

How to use it

1. Enter the network name (SSID) exactly as it appears, including capitals.
2. Choose the security type: WPA/WPA2/WPA3, WEP or none.
3. Enter the password and tick hidden network if the SSID is not broadcast.
4. Generate and download the QR code, then print or display it.

What is inside the code

The QR code contains a short text string in a standard format:

WIFI:T:WPA;S:CafeGuest;P:coffee2026;H:false;;

• T is the security type, S the SSID, P the password and H whether the network is hidden.
• Special characters such as ;, ,, : and backslash in the SSID or password are escaped with a backslash.

Security tips

• Use a guest network for the QR code, separate from devices like your NAS, printers and work laptops.
• Anyone who photographs the code gets the password; do not display it where untrusted people can see it.
• When you change the password, generate and print a new code.
• The code is generated in your browser, so the password is not sent anywhere.

Ideas

Frame it in a guest room, put it on a café table tent, add it to an Airbnb welcome guide or include it on a meeting room sign.
