WiFi QR Codes: Instant Network Connection Sharing
Key Takeaways
- WiFi QR codes encode network credentials (SSID, password, encryption type) in a standardized format that smartphones can automatically connect to.
- The WIFI: URI scheme is supported by iOS (11+), Android, and most modern QR code scanner apps.
- All QR code generation happens in your browser — your WiFi password is never sent to any server.
Sharing WiFi passwords verbally or on paper is inconvenient and error-prone, especially with long, complex passwords. WiFi QR codes encode all connection details in a scannable format — guests simply point their camera and tap to connect. This is especially valuable for businesses, hotels, coworking spaces, and home networks where you want to share access without revealing the password in plain text.
iOS 11+ and all Android versions support automatic WiFi connection from QR codes using the native camera app.

Common Use Cases
Guest Network Access
Print a WiFi QR code for your guest network and display it at reception, in conference rooms, or at event venues for instant connectivity.
Airbnb and Hotel WiFi
Include a WiFi QR code in rental property welcome guides or hotel room cards to eliminate the most common guest question.
Office and Coworking Spaces
Display WiFi QR codes on desks and meeting rooms so new team members and visitors can connect without IT support.
Complex Password Sharing
Share networks with strong, randomly generated passwords (which are difficult to type) by encoding them in a QR code.
Pro Tips
Use a separate guest network for QR code sharing — this isolates guest devices from your primary network for security.
Print QR codes large enough for easy scanning — at least 2cm x 2cm, with adequate contrast against the background.
Update the QR code whenever you change your WiFi password — outdated codes frustrate guests more than no code at all.
Set the encryption type correctly (WPA/WPA2) — an incorrect type will cause connection failures even with the correct password.
All WiFi QR code generation is performed entirely in your browser. Your WiFi credentials (SSID and password) are never transmitted to any server. The QR code is generated locally and can be saved or printed securely.
