Share guest Wi-Fi without typing the password
Example: Network: CafeGuest; security: WPA; password: replace-with-your-guest-password
- Confirm the guest network works and is separate from your private business network.
- Enter the network name, choose WPA, WEP, or Open to match the router, and add the password when required.
- Enable Hidden network only if the router actually hides that network.
- Download the QR, forget the network on a test phone, and check that scanning joins the intended guest network.
What happens after a scan
The code uses a WIFI payload. A compatible phone can offer to join within range of the network; it does not make the router accessible from elsewhere. Changing the name, password, or security settings requires a new QR and replacement signs.
What the code reveals
Anyone who can photograph the QR can read its password. Treat it as a public guest credential. Do not post your staff or home network password on public signs. The code itself does not isolate devices or configure router security.
Using PNG
PNG is a lossless pixel image suitable for documents, websites, and small signs. Export at enough pixels for the final size; enlarging a small image can blur the edges. Keep the code square and preserve its white margin.
