To make a Wi-Fi QR code, put your network details into this standard text format: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; and turn it into a QR code with any generator that accepts plain text. When guests scan it with their phone camera (most iPhones and Android phones can do this natively), the phone offers to join the network without typing the password. Use T:WPA for WPA, WPA2 and most WPA3 networks, T:WEP for very old routers, and T:nopass for open networks.
- A Wi-Fi QR code is just text in a special format.
- Network name (S) and password (P) must match exactly, including capital letters.
- Escape special characters like ; , : and \ with a backslash.
- Use a separate guest network for customers.
- Create it free with the QR Code Generator (choose plain text).
“What’s the Wi-Fi password?”
Picture a busy cafe in Dhanmondi. The staff hear the same question fifty times a day, and the password is “Cafe@Dhanmondi2026#”, which customers mistype twice before it works. A small QR card on each table ends the problem: point the camera, tap Join, done.
It works just as well at home for visiting relatives, in offices for guests, and in hotels, clinics and coaching centres.
The Wi-Fi QR text format
| Field | Meaning | Example |
|---|---|---|
| T: | Security type | WPA (covers WPA/WPA2 and usually WPA3), WEP or nopass |
| S: | Network name (SSID) | S:Cafe_Guest |
| P: | Password | P:Tea2026Time |
| H: | Hidden network (optional) | H:true |
Full example: WIFI:T:WPA;S:Cafe_Guest;P:Tea2026Time;;
abc;123 becomes P:abc\;123.How to create it step by step
