WiFi QR codes for cafés, Airbnbs, and home offices

How to make a WiFi QR code in under a minute, what to print it on, and how to avoid the three mistakes that make hosts re-do them.

A guest walks in, scans a sticker, and is on your Wi-Fi. No password sharing, no typos, no awkward "is it lowercase L or capital I?" moments. Wi-Fi QR codes are one of the simplest hospitality wins of the last decade — and they take about 60 seconds to set up.

How a Wi-Fi QR works

It's a regular QR code that encodes a special string in the format WIFI:T:WPA;S:NetworkName;P:Password;;. When a phone's camera scans it, iOS and Android both recognise the format and offer a "Join 'NetworkName'?" prompt. Tap, and you're connected. No password ever displayed.

That's it. There's no app, no service, no account — the data is baked into the QR.

Make one in 60 seconds

  1. Go to capyqr.com
  2. Click the Wi-Fi tab in the type picker
  3. Type your network name (SSID) exactly as it appears on your router
  4. Pick the encryption type — WPA / WPA2 / WPA3 is right for ~99% of home and small-business networks
  5. Type the password
  6. (Optional) check Hidden network if your SSID isn't broadcast
  7. Pick a design — colours, dot style, or just hit a preset
  8. Download SVG (for printing) or PNG (for screens)

What to print it on

Three mistakes hosts have to redo

1 · Printing it before testing it. Type your SSID in wrong by one character and you'll print 50 stickers nobody can use. Always scan the generated QR with two different phones before printing more than one.

2 · Forgetting that "Hidden network" is a setting. If your network is hidden (most home networks aren't), you must check the Hidden box, otherwise the QR works but the phone won't actually find the network to join.

3 · Putting the QR somewhere it can't be scanned. A sticker behind a glass cabinet can produce glare. A QR on a fridge that's in the dark needs a phone with a good low-light sensor. Pick a flat, non-reflective surface in normal lighting.

Sample WiFi QR (real, but encodes a fake network)

Encodes the network "CafeMochiGuest" with the password "thequickbrownfox" — try it; your phone should offer to join. Mint preset: friendly café-window vibe.

That's a placeholder network so it won't actually connect, but the format is real — a phone with QR scanning will pop the join prompt.

What about your "real" network vs a guest network?

Don't put the QR for your private home network on a sticker that visitors can see. Instead, set up a guest network on your router (most consumer routers in the last decade support it natively). Print the QR for the guest network, leave the private one off the sticker.

Most cafés, coworking spaces, and Airbnbs already do this — guest networks give visitors internet access without exposing your devices on the same LAN. The Wi-Fi QR makes the guest-network experience genuinely frictionless.

Privacy note

With Capy QR specifically: the Wi-Fi QR generation runs in your browser. Your SSID and password are never sent to our servers — they go directly from your input field into the QR image, which is generated locally and downloaded to your device. We never see them.
