Do WiFi QR codes work on iPhone?

Yes. iPhones running iOS 11 or later can scan WiFi QR codes natively using the built-in Camera app — no third-party app needed. Point the camera at the code and tap the notification to join the network.

Do WiFi QR codes expire?

No. A WiFi QR code stores the network name and password directly in the pattern. It will work for as long as your WiFi password stays the same — there is no expiry or renewal.

What if I change my WiFi password?

If you change your WiFi password, the old QR code will no longer work because the password is encoded in the code itself. You will need to generate a new QR code with the updated password and reprint it.

Can I password-protect a WiFi QR code?

No — the WiFi password is embedded inside the QR code itself, so anyone who can scan the code can read the password. For shared spaces, use a separate guest network and put that password in the QR code, keeping your main network private.

WiFi QR Code Guide: Let Guests Connect With One Scan

No more spelling out your password letter by letter.

A WiFi QR code lets anyone connect to your network by pointing their phone camera at it — no typing, no asking. Phones running iOS 11+ and Android 10+ support this natively in the camera app.

How it works

The code encodes a small standard string: WIFI:T:WPA;S:NetworkName;P:password;; — security type, network name (SSID), and password. The phone reads it and offers to join the network. The password is stored in the code itself, so treat the printed code like the password it contains.

Who uses these

Cafés & restaurants — table tents and counter cards reduce "what's the WiFi?" interruptions
Hotels, Airbnbs & guest rooms — frame it next to the router or in the welcome book
Offices — a guest-network code at reception keeps the staff network private
Home — stick one on the fridge for visiting family

Tips for a code that always works

Use your guest network rather than your main one where possible.
If your SSID or password contains ; , : " \ characters, your generator must escape them — QRCraft handles this automatically.
If you change the WiFi password, the printed code stops working — you'll need to print a new one (the code stores the password, it doesn't sync).
Print at least 3×3 cm and test-scan from arm's length before laminating.
