What is a WiFi QR Code?

A WiFi QR code stores your network credentials — the name (SSID), password, and security type — in a format any smartphone camera can read. When someone scans it, their phone immediately asks if they want to join the network. One tap and they're connected. No password is shown, no manual typing required.

It uses the standard WIFI: URI scheme that iOS and Android both understand natively, so there's no app to install and nothing special to set up on the router side.

How to Create One

1. Type your Network Name (SSID) exactly as it appears in your WiFi settings — capitalisation matters.
2. Pick the Security Type. WPA/WPA2 is what virtually every modern router uses. WEP is for older hardware. Open means no password at all.
3. Enter your password and use the eye icon to double-check what you typed before generating.
4. Tick Hidden Network if your SSID doesn't appear in the network list.
5. Preview the QR, adjust size and colours if you need to, then download as SVG (for print) or PNG/JPEG (for screens).

Is My Password Safe?

Yes — everything runs entirely inside your browser. Your WiFi password is never sent to any server, stored in a cookie, or logged anywhere. You could switch off your internet connection completely and this tool would still work. The password literally never leaves your device.

That said, treat the printed QR code the same way you'd treat a written password. It's fine on your fridge for family, fine on a table card in your café, but don't post it publicly online if it's for your main network.

Which Devices Can Scan It?

Most modern phones handle WiFi QR codes without any extra app:

• iPhone (iOS 11 and later) — point the built-in Camera app at the code, tap the banner notification, done.
• Android 9 and later — scan from the Camera app or straight from the WiFi settings screen.
• Older phones — any QR scanner that supports the WIFI:scheme (Google Lens, for example) will work fine.

Where People Use This

• Stick one on the fridge at home. Guests connect without ever asking for the password, and people who always forget it can just scan instead of bugging you.
• Cafés and restaurants put a laminated card on each table. Customers get online instantly. Change the password monthly, reprint the card — that's the whole maintenance process.
• Offices and co-working spaces save the awkward "what's the WiFi again?" moment every time a contractor, new hire, or visitor walks in.
• Event organisers print it on banners or lanyards so everyone connects the moment they arrive — no announcement needed, no queue at the helpdesk.
• Airbnb and short-term rental hosts put it in the welcome pack. Guests get online the moment they arrive without calling or messaging you about it.

A Few Practical Tips

• Use the eye icon in the password field to confirm what you typed before generating — a wrong character means nobody can connect.
• SVG is the right format for anything printed. It stays sharp at any size, from a business card to a poster.
• PNG or JPEG works well for digital use — websites, welcome emails, digital signage.
• Keep the contrast high. Dark dots on a white background or light dots on a dark background both scan reliably.
• Always test-scan the QR before printing a batch or displaying it publicly.
• If you change your WiFi password, you'll need to regenerate the QR. The old one will stop working.
