What Is a WiFi QR Code?
A WiFi QR code encodes your wireless network credentials — the network name (SSID), password, and security type — into a scannable QR code. When someone scans the code with their smartphone camera, their device automatically connects to your WiFi network without needing to type in a password.
This works natively on iOS (iPhone), Android, and most modern devices. There is no app to download and no extra steps. Just point, scan, and connect.
How WiFi QR Codes Work
A WiFi QR code stores your network details in a standard format that smartphone operating systems recognize. The code contains:
- SSID: The name of your WiFi network.
- Password: The network security key.
- Encryption type: WPA/WPA2, WEP, or open (no password).
- Hidden network flag: Optional indicator if your network is not broadcasting its SSID.
QRBuilt generates the WiFi QR code entirely in your browser. Your network credentials never leave your device — no data is uploaded to any server.
Security Tip: Only share your WiFi QR code with people you trust. Anyone who scans it gains access to your network. For public-facing businesses, consider setting up a dedicated guest network with limited access before generating a QR code.
Supported Security Types
- WPA/WPA2 (recommended): The most widely used security protocol for modern routers.
- WEP: An older security standard. Still supported for legacy devices.
- None (Open): For public or guest networks with no password. Use with caution.

Frequently Asked Questions
How do WiFi QR codes work?
A WiFi QR code stores your network credentials (SSID, password, and security type) in a standardized format called WIFI:URI. When scanned with a smartphone camera, iOS and Android recognize this format and prompt the user to join the network automatically. No password typing required.
Are WiFi QR codes secure?
Yes and no. WiFi QR codes are safe to print and share with trusted guests, but they expose your WiFi password to anyone who scans the code. For businesses, we recommend a separate guest network with its own QR code rather than sharing the main network password.
Which WiFi security types are supported?
QRBuilt supports WPA/WPA2 (the most common modern standard), WEP (legacy for older devices), and open networks with no password. The QR code stores the exact security type so phones connect with the right protocol.
Do WiFi QR codes work on all phones?
Yes, on iOS 11+ and Android 10+, the built-in camera app recognizes WiFi QR codes natively without any third-party app. Older phones may need a QR scanner app that supports WiFi network joining.
Where should I place my WiFi QR code?
Common locations: cafes and restaurants on every table, hotels at check-in desks and inside rooms, offices in meeting rooms and reception areas, retail stores at the entrance, and home on the fridge or near the router. Laminate the printout to protect it from spills and damage.
