Create WiFi QR Codes for Instant Network Sharing

A WiFi QR code lets anyone connect to your network by simply scanning with their phone camera — no typing long passwords, no spelling out complex credentials, no case-sensitivity confusion. Both iOS (11+) and Android (10+) natively recognize WiFi QR codes and prompt the user to join the network automatically.

WiFi QR Code Format

WiFi QR codes use a standardized text format that mobile operating systems recognize:

WIFI:T:WPA;S:MyNetworkName;P:MyPassword123;H:false;;

The parameters are:

  • T (Type) — authentication type: WPA (covers WPA2 and WPA3), WEP, or nopass for open networks
  • S (SSID) — the network name, exactly as it appears in WiFi settings
  • P (Password) — the network password, case-sensitive
  • H (Hidden) — true if the network SSID is hidden, false otherwise

Special Characters in SSID or Password

If your network name or password contains special characters, they must be escaped with a backslash:

# Characters that need escaping: \\ ; , \" :
WIFI:T:WPA;S:My\\;Network;P:pass\\:word\\!;;

Common Use Cases

  • Restaurants and cafes — print the QR code on table tents, receipts, or the menu. No more asking the server for the password.
  • Hotels — place QR codes in guest rooms instead of printing credentials on key card holders
  • Offices — share guest WiFi credentials in meeting rooms without revealing the main network password
  • Airbnb and rentals — frame a QR code near the router so guests connect instantly on arrival
  • Events and conferences — display on screens, badges, or signage for attendee WiFi access

WPA2 vs WPA3

Both WPA2 and WPA3 networks use T:WPA in the QR code format. The phone handles the protocol negotiation automatically. If your router supports WPA3, the phone will use it when possible. There is no separate T:WPA3 value in the standard.

Security Considerations

  • Separate guest network — create a dedicated guest network with bandwidth limits, isolated from your main network
  • Rotate passwords — change the guest password periodically and reprint the QR code
  • Physical access control — anyone who can see or photograph the QR code gets the password, so place it appropriately
