Share Your WiFi with a QR Code (Home & Business Guide)

"What's the WiFi password?" is the most-asked question in every home and café. A WiFi QR code retires it permanently: guests point their camera, tap one prompt, and they're connected — no spelling W-P-A passwords across the room.

How a WiFi QR code works

The code encodes three things in a standard format every phone understands: your network name (SSID), the password, and the security type (almost always WPA/WPA2). When a phone camera reads it, the operating system itself — not a third-party app — shows a "Join network" prompt. One tap connects. The standard is supported natively on iPhone (iOS 11+) and Android (9+), which covers practically every phone in use.

Make one in 30 seconds

Open our WiFi QR code generator, type the network name and password, choose the security type, and download. The code is generated entirely in your browser — your password is never uploaded anywhere, which matters for exactly this use case. Print it, frame it, done. Since the credentials are baked into the pattern, it's a static code: it works forever, offline, with no account — until you change your password, at which point you generate a fresh one (free, every time).

Where to put it

Home: a small framed card on the entry shelf or fridge — guests help themselves.
Café / restaurant: table stickers or a counter stand. Pair it with your menu QR; our sticker maker prints a full A4 sheet of identical codes for every table.
Guest house / Airbnb: in the welcome binder and on the router itself.
Office: meeting-room walls for visitors, so reception stops fielding the question.

Add a one-line label — "Scan to join our WiFi" — so people know what the code does before scanning.

Security: do it the smart way

Use a guest network. Nearly all modern routers can broadcast a second network isolated from your main devices. Make the QR code for the guest network — visitors get internet, your laptops and cameras stay separated.
Remember the code equals the password. Anyone who can photograph the code has the credentials, exactly as if they'd read the password off a chalkboard. Place it where only guests see it, not in a street-facing window — unless free WiFi for passers-by is the point.
Rotate occasionally. For businesses, changing the guest password quarterly and reprinting one sticker sheet keeps old captures from accumulating.

Troubleshooting

"Nothing happens when scanning" — usually a typo in the SSID (it's case-sensitive) or the wrong security type selected. Regenerate carefully.
Hidden network? Tick the "hidden network" option when generating so phones know to search for it.
Old phone won't auto-join — very old Android versions show the password as text after scanning; the guest can copy-paste it manually.
