Free Wi-Fi QR code generator for rental hosts

How to use it

1. Type your network name exactly. "CasaVerde_5G" and "Casaverde 5g" are different networks to a phone. Copy it from your own device's Wi-Fi list rather than from memory.
2. Pick WPA unless you know your router is genuinely ancient. WPA covers WPA, WPA2 and WPA3.
3. Enter the password and check it character by character. This is the step that goes wrong.
4. Test it on a phone that isn't already connected. Forget the network first, or use a friend's phone. A code that "works" on a device already joined to the network has told you nothing.
5. Print the card and put it where guests look first — by the door, on the desk, or next to the kettle. Not inside a drawer.

Does it work on iPhone and Android?

iPhone: yes, straight from the Camera app. iOS 11 and later recognise Wi-Fi QR codes natively — the guest points the camera, a banner drops down, they tap it, they're on. Nothing to download.

Android: yes, but where it lives varies by manufacturer. Wi-Fi QR sharing and scanning has been built into Android's system settings since Android 10, and most modern camera apps (or Google Lens) read the codes too. If a guest's camera doesn't react, Settings → Wi-Fi → the scan icon almost always works.

The failures you'll actually see are older budget handsets and locked-down work phones. That's exactly why the printed card has an option to show the password as text underneath — belt and braces, one piece of paper.

Where hosts should actually put the code

• By the entry door, at eye level. It's the first surface a guest touches.
• On the desk or nightstand, where people sit down with their phone.
• In the kitchen, near the kettle or coffee machine.
• Not on the router itself, stuffed in a binder, or laminated to the back of a cupboard door. If a guest has to hunt for it, they'll message you instead — which is the thing you were trying to avoid.

One card per floor is not overkill in a larger property. They cost a sheet of paper.

When the code doesn't scan

• Nothing happens when the camera sees it. Nine times out of ten the network name has a typo, or a trailing space that got pasted in. Regenerate and re-test.
• It connects, then drops. The password is wrong, or the security type is set to WEP when the router is WPA.
• It works for you but not for a guest. Your phone was already on the network. Always test on a device that has never joined.
• Printed too small. Below about 3 cm (1.2 in) square, cheap phone cameras struggle. Print the card at full size rather than shrinking it onto a business card.
• Glossy laminate under a downlight. Glare kills scans. Matte paper, or move the card out of direct light.
• Guest network with a captive portal (a sign-in page). QR codes join the network but can't click through a login page — those setups need the portal disabled for guests, or a different approach entirely.

Is a Wi-Fi QR code safe to put on the wall?

Be clear-eyed about what it is: the code contains your network name and password in plain text. Anyone who can see the card — or photograph it through a window, or find a photo of your listing that happens to include it — can read the password with any QR scanner. That is no worse than printing the password on a card, which is what most hosts already do, but it is no better either.

If that matters to you, the fix is the one hotels use: run a separate guest network on your router (most modern routers have a "Guest Wi-Fi" toggle), give that network its own password, and generate the code for that one. Your own devices, cameras, and network storage then sit on a different network that guests never touch. Change the guest password once or twice a year and reprint the card.
