How Wi-Fi QR Codes Work
Wi-Fi QR codes use the standard WIFI protocol string (WIFI:S:NetworkName;T:WPA;P:Password;;). Both iOS (Camera app) and Android (Google Lens / Camera) natively parse this protocol format.
When scanned, the operating system asks the user for confirmation: "Join [Network Name] Network?" Tapping Join connects the device automatically without revealing the plain-text password to passersby.
Three Steps to Create Your Wi-Fi QR Code
1. Select Wi-Fi Mode: Open makeaqrcode.app/qr-code-generator/wifi and choose your security encryption (WPA/WPA2, WEP, or Open).
2. Enter Network Name (SSID) & Password: Enter your exact network SSID and Wi-Fi security key. Check the "Hidden Network" toggle if your router does not broadcast its SSID.
3. Export High-Res PNG or Vector SVG: Download your code in 300+ DPI. Print it on a tabletop stand, sticker, or entrance sign for easy customer scanning.
Security & Privacy Best Practices
Always generate Wi-Fi QR codes for guest networks rather than primary business admin networks. This keeps internal file shares and sensitive devices segregated from visitor traffic.
Static Wi-Fi QR codes encode your network credentials locally in your browser, meaning your password is never stored or transmitted to external servers.

No. The native camera app on modern iOS and Android devices recognizes Wi-Fi QR codes automatically.
Does makeaqrcode.app store my Wi-Fi password?
No. Wi-Fi QR codes are generated entirely client-side using direct vector rendering. Your credentials never leave your browser.
