Nobody enjoys typing xK9#mPq$2w on a tiny phone keyboard. A WiFi QR code lets people scan and connect to your network instantly — no typing, no mistakes, no asking the waiter three times.
Here's how to create one and where to use it.
How WiFi QR Codes Work
A WiFi QR code stores your network credentials in a specific format that phones understand natively. When someone scans it, their phone reads the network name, password, and encryption type, then offers to connect automatically.
The format looks like this internally:
WIFI:T:WPA;S:MyNetwork;P:mypassword123;;
But you don't need to write this yourself. A QR code generator handles the formatting — you just enter your network details.
Both iOS (since iOS 11) and Android support WiFi QR codes through the default camera app. No third-party app needed.
How to Create a WiFi QR Code
- Go to qree.app
- Select the WiFi tab in the QR generator
- Enter your network name (SSID) — exactly as it appears in your WiFi settings
- Enter the password
- Select encryption: WPA/WPA2 (most common), WEP, or None
- Check "Hidden network" if your network doesn't broadcast its name
- Customize colors and style if you want
- Download PNG or SVG
That's it. Print it, display it, and your guests can connect in one scan.
Where to Use WiFi QR Codes
Cafes and restaurants. Print the QR on a table tent, a sticker near the counter, or on the wall. No more shouting "The password is all lowercase, no spaces, with a dollar sign."
Hotels and Airbnbs. Place the QR in the room — on the desk, nightstand, or welcome card. Guests arriving late at night don't need to call reception for the WiFi password.
Offices and coworking spaces. Put a QR at the reception or in meeting rooms. Visitors and freelancers connect instantly. If you have a separate guest network, create a QR specifically for that.
Events and conferences. Display the QR on the registration desk, on screens between sessions, or on the badge lanyard. Hundreds of people trying to connect at once? A QR code eliminates the bottleneck.
Shops and salons. Offering free WiFi to customers? Make it easy. A QR code near the entrance or at the waiting area.
Security Considerations
A WiFi QR code contains your password in plain text (encoded in the QR pattern). This means anyone who scans it can see the password if they decode the QR. For a guest network, this is fine — the password is meant to be shared.
For sensitive networks:
- Use a separate guest network with its own password
- Change the guest password periodically and regenerate the QR code
- Don't use a WiFi QR for your private or admin network
If you change the WiFi password, you'll need to create a new QR code. WiFi QR codes are static by nature — the credentials are stored directly in the QR image.
Tips
Match the SSID exactly. If your network is called "Cafe_Guest" (with an underscore), type it exactly that way. A single character difference and it won't connect.
Specify the right encryption. WPA/WPA2 is the standard for most modern routers. If you pick the wrong type, the connection will fail silently.
Print it big enough. At least 3×3 cm. If it's on a wall, bigger. People will be scanning from their seat, not holding their phone right next to the QR.
Add a label. Print "Scan to connect to WiFi" next to the QR. Without context, people won't know what the QR does.
Test after printing. Scan the printed QR with your own phone. Make sure it connects to the right network with the right password.
