How to Make a QR Code for Your Wi-Fi
Create a QR code that connects guests to your Wi-Fi with one scan, print it so it scans reliably, and keep your network safe while sharing it.

Quick answer
Open the Wi-Fi QR Code Generator, enter your network name and password exactly, choose the security type (usually WPA/WPA2/WPA3), and download the code. Guests open their phone camera, point it at the code and tap the notification to join — no typing.
Spelling out a 16-character Wi-Fi password to every guest gets old fast. A Wi-Fi QR code solves it: iPhones (iOS 11 and later) and Android phones read the standard Wi-Fi QR format straight from the camera app.
Make the code
- 1Find your network name (SSID) and password — often on a sticker on the router, or in your phone's Wi-Fi settings.
- 2Enter them exactly. Both are case-sensitive, and spaces count.
- 3Choose the security type. Almost all home networks today use WPA2 or WPA3; pick “WPA / WPA2 / WPA3”.
- 4Download the PNG and print it, or the SVG for a designer.
- 5Test it with two different phones before you frame it.
What's actually inside the code
The QR code simply contains a short text in a standard format:
WIFI:T:WPA;S:MyHomeNetwork;P:correct-horse-battery;;T is the security type, S the network name and P the password. Special characters like ; , : and " are escaped with a backslash — the generator does this for you, which is a common reason home-made codes fail.
Printing it so it scans every time
| Tip | Why |
|---|---|
| At least 3 × 3 cm (1.2 in) | Small codes are hard to focus on |
| Dark code on a light background | Many phones can't read inverted codes |
| Keep the white border | Scanners need the “quiet zone” to find the code |
| Matte paper, no glare | Reflections hide parts of the pattern |
| Add a line of text: “Scan to join our Wi-Fi” | People recognise what it's for |
Keeping your network safe
Anyone who can see the code can join your network — just like anyone who knows the password. For homes with frequent visitors, Airbnbs, offices and cafés, set up a separate guest network on your router and put that in the QR code. Guests get internet access without seeing your other devices.
Frequently asked questions
Do Wi-Fi QR codes work on iPhone?
Yes, on iOS 11 and later: open the Camera app, point it at the code and tap the Wi-Fi notification.
Does the code expire?
No. It contains your network details directly, so it works until you change the network name or password.
Can I make a QR code for a hidden network?
Yes — tick “Hidden network” in the generator so phones know to look for it.
