Free printable WiFi sign with QR code

What is a WiFi QR code?

A WiFi QR code is a square image that holds your network name, its password and the security type. When a guest points their phone camera at it, the phone offers to join the network. They tap the notification and they're online. Nothing to type.

In a vacation rental, that matters. A router password is often twenty mixed characters printed on a sticker on the back of the router. Guests arrive with their bags, hunt for the sticker, get it wrong twice, then text you. The QR code removes that exchange.

What the QR code contains

The QR code doesn't hold a link. It holds a short text string in the format iOS and Android read. For a WPA2 network it looks like this:

WIFI:T:WPA;S:NetworkName;P:Password;;

T is the security type, S is the network name (the SSID) and P is the password. The "Copy code" button gives you that string as is, handy if you want to paste it into another tool or into your digital guidebook. Special characters in the password (semicolons, colons, quotes) are escaped automatically, so the scan restores them exactly.

Your password stays in your browser

Many online generators send your credentials to their server to build the image. Here the QR code is computed on the page itself, by a small library your browser loads. You can turn off your internet connection once the page is open and the QR code will still generate. Nothing is stored, nothing is sent.

The QR code itself isn't encrypted. Anyone who scans it, or opens the image in a reader, gets the password in plain text. That's how it works, and it's why you should think about where you display it.

For a rental, the right move is a guest network on your router. Most routers from Xfinity, Spectrum, AT&T and Verizon offer one in their admin app. A guest network gives internet access but no access to your own devices, such as a printer or cameras. You can also change its password every season without touching your main network. Just generate a new QR code.

Where to put the WiFi sign in your rental

Print the sign on letter paper and put it where guests set down their things when they walk in. A small frame keeps it from walking off, and the QR code stays large enough for a phone camera to focus on:

• on the fridge or next to the coffee maker, where everyone passes in the first hour;
• in a small frame on the coffee table or nightstand;
• next to the router, for guests who look for the sticker out of habit;
• on the WiFi page of your digital guidebook, so guests have it before they even arrive.

Avoid street-facing windows and anywhere visible from outside. A QR code can be scanned from several yards away with a good zoom.

Works on iPhone and Android, no app needed

On iPhone, the camera has recognized WiFi QR codes since iOS 11, released in 2017. On Android, the feature is built into the camera or Google Lens since Android 10, and most Samsung and Pixel phones have had it since Android 9. There's nothing to install on either side.

Laptops don't have a native QR code reader. For them, print the network name and password in plain text under the QR code. That's the guest working remotely.

If the scan doesn't work

• The phone shows nothing: check that the QR code is printed larger than 2 inches and that light isn't glaring off a laminated sheet.
• The connection fails: the security type you picked doesn't match the router. Check in the router's admin page whether the network is WPA2, WPA3 or mixed, then generate the code again.
• The password is rejected: it was changed on the router after you printed. Make a new QR code. The old one is useless now.
• The network is hidden: check the "Hidden network" box before generating. Recent phones connect fine, but some older Android phones can't find a network that isn't broadcast. The simplest fix is to make the guest network visible.
