Wi-Fi QR Code Generator
Print one small square and stop reciting a 24-character password across a room. A phone camera reads the network name and key straight out of the code and offers to join — no app, no typing, no "is that a lowercase L or a one".
Your network name and password are encoded in this page, in your browser. Nothing you type here is sent to our servers, and we never see or store your Wi-Fi key.

Put your guests on the guest network
The code carries your password in plain text. Anyone who photographs it, or who finds the photo later, has your key — a printed Wi-Fi code is a printed password, and it should be treated with the same care. That is a fine trade for a café, a waiting room or a spare bedroom. It is a bad trade for the network your till, your NAS and your work laptop sit on.
Most consumer routers can run a separate guest SSID that reaches the internet but not the other devices on the LAN. Turn that on, generate the code for the guest network, and a photographed code stops being a route into anything that matters.
Security type has to match exactly
Pick WPA for anything modern — the same setting covers WPA, WPA2 and WPA3, which is why you will not find a separate WPA3 option. Choose "No password" only for a genuinely open network; a code that claims a network is open when it is not will fail to connect with an error that names neither the code nor the password. WEP exists for hardware old enough that it should probably be replaced.
Hidden networks need the hidden flag set, or the phone will look for a broadcasting SSID, not find one, and give up. And check the SSID for a trailing space — it is invisible in your router admin page and it will break the match.
What gets encoded
WIFI:T:WPA;S:CafeGuest;P:flatwhite2026;;
The standard Wi-Fi network string: T is the security type, S the network name, P the password. iOS 11 and later and Android 10 and later read it from the stock camera; older Androids may need a QR app.
Questions
Is the Wi-Fi password visible in the QR code?
Yes. The password is stored as readable text inside the pattern, and any QR scanner can display it instead of connecting. The code is a convenience, not an encryption scheme — print it for a guest network and treat the card itself as something you would not photograph and post.
Does it work on iPhone and Android?
On iOS 11 and later, the stock Camera app recognises the network string and offers to join. Android has supported it natively from Android 10. Older Android phones will need a QR scanning app, which reads the same code without any change on your side.
Why does my Wi-Fi QR code scan but fail to connect?
Almost always a mismatch rather than a bad code: the security type is set to WPA on a network that is actually open, the SSID has a stray space or different capitalisation, the network is hidden but the hidden flag was not set, or the password changed after printing. Retype both fields carefully and regenerate.
