WiFi QR Code

How to use it

1. Enter the network name (SSID) exactly as your router shows it; the value is case sensitive.
2. Type the password and pick the encryption type: WPA family, WEP, or None for open networks.
3. Tick Hidden network only if the router does not broadcast the SSID.
4. Click Generate, then let guests scan the canvas or Download the PNG for printing.

Common use cases

• Cafe, shop and office guests - print the code by the till so visitors stop reading passwords aloud.
• Home visits - hand the babysitter or plumber a sheet instead of your password.
• Event venues - put one code per table and rotate the guest password between events.
• Router relabeling - replace the factory sticker with one that matches your own SSID and key.

Why it stays private

The WIFI: string is assembled in your browser and rendered with the same local QR engine as the QR tool. The SSID and password never leave the page, and the downloaded PNG is produced on your device.

FAQ

Q: Can a phone un-share my Wi-Fi from the QR code? A: On most phones the QR only configures the connection, but many systems let a connected user view the saved password or re-share the code. Treat it like the password itself: hand it to people you trust to have network access.

Q: Why does my device fail to connect after scanning? A: Check three things: the SSID must match letter case exactly, the encryption type must match the router, and WEP passwords are hex keys on many routers. If the network is hidden, the Hidden box must be ticked.

Q: Which encryption option should I pick? A: Choose WPA for every modern router, since WPA2 and WPA3 networks use the same WPA marker in the QR format. WEP only exists for very old hardware, and open networks should only be used with a captive portal or guest isolation in place.
