Wi-Fi QR code generator
How it works.
A Wi-Fi QR code holds your network name, security type and password in a standard format that phone cameras understand. When a guest points their camera at it, iPhone and Android show a "Join network" prompt - no reading out passwords, no typos, and no asking staff. Enter your network details above and the code is drawn instantly; download it as a PNG or print a ready-made card.
The code uses the widely supported WIFI: format, for example WIFI:T:WPA;S:Office Guest;P:password;;. T is the security type, S the network name, P the password and H:true marks a hidden network. Special characters - backslash, semicolon, comma, colon and double quote - are escaped automatically, so passwords with symbols work correctly.
Choose WPA / WPA2 / WPA2-WPA3 for almost every network, including routers in WPA2/WPA3 mixed mode; phones work out the exact version when they connect. Use WPA3 only (SAE) if your router is set to WPA3 alone - some older phones may not understand that code type. WEP is only for very old equipment and is easy to crack, so upgrade if you can. Choose None for open networks, such as a hotspot that uses a captive portal login page instead of a password. Tick Hidden network if your SSID isn't broadcast, so the phone knows to look for it.
Your privacy matters here: the QR code is generated entirely in your browser. The network name and password are never sent to Super Next or anyone else, and nothing is saved. You can even disconnect from the internet after the page loads and the generator still works.
Where to use it: on reception desks, meeting rooms, hotel key-card holders, restaurant tables, clinic waiting areas and event badges. Print it at least 3 cm wide so phones can focus easily, keep good contrast (black on white) and test it with both an iPhone and an Android phone before laminating. If you change the Wi-Fi password, make a new code - the old one will stop working.
A shared password suits small offices and cafes. For hotels, residences, labour accommodation and other busy guest networks, a captive portal with individual logins, vouchers, per-user speed limits and usage reports is safer and easier to manage. WiFiNexa, our hotspot management platform, does this on standard MikroTik routers.
Questions, answered.
How do I scan a Wi-Fi QR code?
Open the camera app on an iPhone or Android phone and point it at the code. Tap the "Join network" notification that appears. Older Android phones may need Google Lens or the QR scanner in the Wi-Fi settings screen.
Is it safe to put my Wi-Fi password in a QR code?
The code is created in your browser and never leaves your device. Anyone who scans the printed code can read the password, though, so use it for a guest network that is separated from your business systems, and change the password if the code is posted publicly.
Does it work with WPA3?
Yes. If your router runs WPA2/WPA3 mixed mode, choose WPA / WPA2 / WPA2-WPA3. If it is set to WPA3 only, choose WPA3 only (SAE). Recent phones support both; if an older phone can't join a WPA3-only network, switching the router to mixed mode usually solves it.
Can I make a QR code for a hidden network?
Yes. Tick Hidden network so the code includes H:true. The phone will then try to connect even though the network name isn't broadcast.
Does the QR code expire?
No. It's a fixed image of your network details, so it works until you change the network name or password. After a change, generate and print a new code.
Can I print it?
Yes. Use Print for a simple card with the code, network name and password, or Download PNG for a high-resolution image to add to your own signs and table cards.
