How to Make a WiFi QR Code (Free) — Guests Scan to Connect
A WiFi QR code lets guests join your network by pointing their phone camera at it — no reading out the password, no typos. It's perfect for a café, a shop, an office, an Airbnb or just your living room. This guide shows you how to make one for free, and how to make it last forever.
Quick answer
To make a WiFi QR code for free: (1) open a QR code generator and choose the WiFi type, (2) enter your network name (SSID), password and security type (usually WPA/WPA2), (3) download the code as PNG or SVG, and (4) print it where guests can see it. Use a static WiFi QR code so it never expires — OneSol's free QR generator at onesol.io/qr-code-generator makes one with no signup.
1. Get your network details
You need three things: the exact network name (SSID), the password, and the security type — for almost every modern router that's WPA/WPA2. Match the name and password exactly, including capital letters, or phones won't connect.
2. Generate the WiFi QR code
In a QR generator, pick the WiFi option and fill in the SSID, password and security type. The code appears instantly. Choose a static code so the details are baked into the pattern and it keeps working forever — no account or subscription behind it.
3. Download and print it
Download the code as a PNG for a sign or an SVG for large or high-quality print. Add a short line like “Scan to join our WiFi”. Keep strong contrast and leave the white border so cameras read it easily.
4. Place it where guests look
Common spots: a table tent in a café, a framed card by the door, the fridge in an Airbnb, or a sticker at reception. Print it at least about 2 × 2 cm and test-scan it from where people will actually stand.
FAQ
Is a WiFi QR code safe?
It's as safe as sharing your password any other way — the QR simply contains your network name and password so a phone can fill them in automatically. Only put it where you'd be happy handing out the WiFi password, and use a separate guest network if you want to keep your main one private.
Does a WiFi QR code expire?
Not if it's static — the network details are encoded in the pattern itself, so it works forever with no account behind it. It only stops working if you change the WiFi name or password, in which case you generate a new code.
Do WiFi QR codes work on iPhone and Android?
Yes. Modern iPhones and Android phones read WiFi QR codes straight from the camera app — the phone shows a “Join network” prompt when you point it at the code.
What if my password has special characters?
That's fine — enter it exactly as it is, including symbols and capital letters. The QR encodes it verbatim. Just double-check it matches your router exactly, then test-scan before you print copies.
