How to Make a WiFi QR Code (Free): Guests Join in One Scan

Reading a 20-character WiFi password off the back of a router is nobody's favorite party game. A WiFi QR code fixes that: guests point their phone camera at it, tap once, and they're online. Here's how it works, what to enter, and how to print one that keeps working for years.

How a WiFi QR code works

Unlike most QR codes, a WiFi code doesn't open a website. It stores your network details as a short piece of text in a standard format that phones understand. In plain words, it looks like this:

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;

• T is the security type (WPA, WEP, or none for an open network).
• S is the network name (SSID), exactly as it appears in your WiFi list.
• P is the password.
• The two semicolons at the end close the code.

You don't have to type any of this yourself — a generator builds it for you. But knowing the format helps when something doesn't connect: nine times out of ten, the network name or password has a typo or a wrong capital letter.

Step by step: make yours for free

1. Open the free WiFi QR code generator.
2. Type your network name exactly as it appears on your devices. Names are case-sensitive: "HomeWiFi" and "homewifi" are different networks.
3. Enter the password and pick the security type.
4. Download the code and test it with your own phone before you print anything.

Choosing the right security type

Most home and business routers made in the last decade use WPA2 or WPA3; both go under "WPA" in the code. WEP is an outdated standard found only on very old routers, and it's easy to crack — if that's what yours uses, it's time to upgrade. Choose none only for a truly open network with no password. If you're not sure, look at the sticker on your router or the WiFi settings on a connected laptop.

Hidden networks

If your network doesn't broadcast its name, phones can't see it in the WiFi list. The standard format has an extra flag (H:true) that tells a phone the network is hidden, but support varies between phones, so test the code on both an iPhone and an Android before printing. Enter the name very carefully — with a hidden network there's no list to double-check against. Hiding a network adds very little real security, so for a guest code it's usually simpler to let the network broadcast its name.

Do iPhone and Android scan it?

Yes. On a modern iPhone, open the Camera app, point it at the code and tap the "Join network" banner. Most Android phones do the same from the camera or the Quick Settings QR scanner. No app is needed on either platform. Older phones may need a free scanner app.

Where to put your WiFi QR code

• Home: a small framed card in the guest room or on the fridge. Visiting family will thank you.
• Airbnb and vacation rentals: in the welcome binder and next to the TV. It cuts down on "what's the WiFi?" messages.
• Cafés and restaurants: on table tents or at the register. Size it at least 1.5 in (4 cm) so it scans from a seat.
• Offices and waiting rooms: use a separate guest network and put that code at reception — never share your main business network.

Print it dark on a light background and leave the white margin around it. Our printing guide covers size and contrast in detail.

One thing to know: it's a static code

The password lives inside the code itself. If you change your WiFi password, the old code stops working and you'll need to make and print a new one. That's why it's smart to keep guest-network passwords stable. Need a code for something else — a link, an email, a phone number? See all our free QR code generators.

For Airbnb hosts: WiFi plus house rules on one page

If you'd rather give guests everything in one scan — check-out time, house rules, parking notes, local tips, photos of how the coffee maker works — design a small QRLivo page and put the WiFi details there too. The page can be updated whenever your rules change, and the printed code stays the same.
