WiFi QR Code: Share Network Instantly
Definition: A WiFi QR code encodes network name (SSID), password, and encryption type in a standardized format that auto-connects devices when scanned.
WiFi QR codes use the format WIFI:S:NetworkName;T:WPA;P:Password;; to encode connection details. When scanned, the phone automatically connects to the network — no manual password entry needed. This is especially useful for businesses (restaurants, hotels, offices), guest networks, Airbnb properties, and events. Both iOS (11+) and Android natively support WiFi QR auto-connection.

Frequently asked questions
How do I create a WiFi QR code?
Enter your network name (SSID), password, and security type (usually WPA/WPA2) into a WiFi QR generator. Download and print the resulting code.
Does WiFi QR work on iPhone?
Yes — iPhone (iOS 11+) supports WiFi QR codes natively through the Camera app. Scan the code and tap the "Join Network" notification.
Is sharing WiFi via QR code secure?
The QR code contains the password, so anyone who can scan it gets access. Use it for guest networks, not your primary secured network.
