Free WiFi QR Code Generator
Typing out a long WiFi password for every guest gets old fast. A WiFi QR code solves this in one scan — point a phone camera at the code, tap the prompt, and the device connects automatically. No app to download, no password to type or misread.
How it works
A WiFi QR code stores your network name (SSID), password, and security type (usually WPA/WPA2) inside the code itself. Most modern phone cameras — iPhone and Android alike — can read this directly through the native camera app, no separate QR scanner needed.
Who uses WiFi QR codes
- Cafés and restaurants placing a printed card on each table so customers connect without asking staff
- Airbnb hosts and hotels leaving a card on the nightstand or fridge for guests
- Offices printing a small card for the guest network at reception
- Home users who want to stop reciting their password to every visitor
Creating your WiFi QR card with CardQR
- Open the WiFi Sharing template
- Enter your network name and password
- CardQR generates a scannable card with a tap-to-copy password option as a fallback for devices that don't support auto-connect
- Download the QR code as a print-ready SVG or PNG, or share the link directly
Your WiFi card stays editable — if you change your password, update the card without reprinting anything, as long as you keep the codeless, you'll need to regenerate and reprint your QR code, since the new password is embedded directly in the code.
Is it secure?
Sharing a WiFi QR code is no less secure than sharing the password verbally or in writing — the code simply encodes the same information. Don't post your WiFi QR code somewhere the general public can scan it unless you're comfortable with anyone in range joining your network, just as you would with the password itself.
Frequently asked questions
Does the guest need an app to scan it?
No. Modern iPhones (iOS 11+) and most Android phones (Android 10+) can scan and connect via the built-in camera app.
Can I change the password later without reprinting?
The QR code itself is tied to the password it was generated with. If you change your WiFi password, you'll need to generate and print a new code.
Does this work for 5GHz and 2.4GHz networks?
Yes — the QR code simply stores your network name and password; it works for any standard WiFi network regardless of band.
