WiFi QR Code Generator — scan to connect, no password typing
Turn your WiFi name and password into one QR code, stick it up in your shop, rental or by the front door, and guests scan to connect instantly — no more reading out a long password. QR Cat builds it entirely in your browser; the WiFi password is never uploaded, full stop. The result is a static code that never expires.
A WiFi QR code encodes the network name (SSID), security type and password in a standard format. iPhones (iOS 11+) and most Androids scan it with the built-in camera, show a 'Join Network' prompt, and connect — no typed password, no app. Fill in the SSID and password below to generate. The password is encoded locally in your browser and never uploaded.

What's behind 'scan to connect'
A WiFi code isn't a picture — it's a short line of standard text shaped like WIFI:T:WPA;S:NetworkName;P:password;;. When the camera reads it, the phone recognizes a 'join this WiFi' instruction and offers to connect — the password is already inside, so you never type it. That's also why it shines with complex passwords: however long or messy, to a scanner it's just text that fills in instantly, with no chance to misread or mistype.
Convenience is not secrecy (an honest note)
A QR code buys convenience, not secrecy. The code holds the network name and password in plain text, so anyone who photographs it effectively has the password — no different from you saying it aloud. Don't post your main network's code where strangers can see it; put guests on a separate guest network with its own password, so even if the code walks off it can't reach your main network or internal devices. Change the password and you must regenerate and swap the old code.
Frequently asked questions
Does scanning a WiFi code connect automatically?
Yes. iPhones (iOS 11+) and most Android phones, pointed at a WiFi QR code with the built-in camera, show a 'Join Network' prompt — one tap and you're on, no typed password and no extra app.
Which security type should I pick?
Most home and business routers use WPA / WPA2 — pick that. Very old gear might use WEP; a fully open, password-free network uses 'None.' When in doubt, choose WPA / WPA2.
I changed my WiFi password — does this code still work?
No. A static WiFi code carries the password as it was, so after a change you regenerate a fresh code. The upside is no server dependency and it never expires; the cost is redoing the code on a password change — a safer trade for something as sensitive as WiFi.
