Wi-Fi QR Codes: The Simple, Secure Way to Share Network Access

Connect guests in seconds—no typing, fewer mistakes.

Typing long Wi-Fi passwords is tedious and error-prone. A Wi-Fi QR code lets guests join instantly by scanning with their camera. It’s faster, cleaner, and more secure than writing your password on a sticky note.

Wi-Fi QR code format

Most devices understand the WIFI: format:

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;H:false;;
  • T: Security type (WEP, WPA, or leave empty for none).
  • S: SSID (network name).
  • P: Password.
  • H: Hidden network? true or false.

Security tips

  • Use WPA2 or WPA3 with a strong password.
  • Create a guest network so visitors don’t access devices on your main LAN.
  • Rotate the password occasionally, especially for public locations.
  • Don’t post the QR publicly if your network isn’t meant for everyone.

How to generate a Wi-Fi QR in seconds

  1. Visit FreeQRHub.
  2. Paste the Wi-Fi string (or just your SSID/password—the tool handles plain text too).
  3. Choose colors or keep high-contrast black on white.
  4. Set error correction to Q or H if adding a logo.
  5. Download as PNG (prints nicely) or SVG (crisp at any size).

Great placements

  • Reception desks and host stands
  • Conference rooms and coworking spaces
  • Vacation rentals (print inside the welcome guide)
  • Home entryway or router cabinet door (for family/guests)

Troubleshooting

  • If scanning fails, increase the code size and contrast.
  • Make sure your camera app supports Wi-Fi QR codes (most do).
  • Remove emojis or special characters from SSID if devices struggle.
