How to Create a Wi‑Fi QR Code Guests Can Scan

Published 2026-08-03

A Wi‑Fi QR code stores your network name and password in a standard format phones understand. Guests scan it with their camera app and join without typing a long passphrase. You can generate one entirely in the browser — no need to upload credentials to a third-party server.

What goes into a Wi‑Fi QR

Most phones expect a payload like this:

WIFI:T:WPA;S:MyNetwork;P:MyPassword;;
  • T — encryption type (WPA, WEP, or nopass)
  • S — SSID (network name)
  • P — password (omit for open networks)
  • H:true — optional flag for hidden networks

Steps

  1. Open the QR Code Generator and switch to Wi‑Fi mode.
  2. Enter the SSID and password exactly as the router uses them.
  3. Choose WPA/WPA2 for modern routers.
  4. Generate the code and download the PNG.
  5. Print it or place it on a welcome card — keep a digital copy only where you trust the device.

Privacy and security

  • Anyone with the QR can join while that password is valid. Rotate the guest password if the printout spreads too far.
  • Prefer a separate guest network instead of sharing your main LAN password.
  • Generate codes locally. Avoid “free QR” sites that upload Wi‑Fi secrets to their servers.

FAQ

Do all phones support Wi‑Fi QR codes?

Most current iOS and Android camera apps do. Older devices may need a QR scanner app.

Can I put a website link in the same QR?

One QR encodes one payload. Use a separate QR for a URL or WhatsApp chat link.
