The format scanners expect#

Most iPhone/Android camera scanners understand this “WIFI:” payload (a de-facto standard):

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;H:false;;
  • T: encryption type — use WPA for WPA/WPA2/WPA3, WEP for old routers, or nopass for open networks.
  • S: SSID (WiFi name)
  • P: password (omit if T:nopass)
  • H: hidden network (true/false)

Special characters that break scans#

If your SSID or password contains ; , : or \, some scanners fail unless the value is escaped. QRFlow handles this by escaping those characters in the WiFi payload.

Practical tip: if scans fail, test with a simpler password (letters + numbers) or regenerate after copying the exact router values (case-sensitive).

Hidden networks#

Hidden SSIDs are less reliable across devices. If you must use one, set Hidden network to true and keep the QR large enough for comfortable scanning.

  1. Open the WiFi template.
  2. Copy/paste SSID and password from the router settings (avoid manual typing).
  3. Test on at least one iPhone and one Android.
  4. Download SVG for print-ready signage (cafes, offices, event badges).
