Build a Wi-Fi QR code in LEGO

It encodes your network name, password, and security type. Scanning it with a phone camera offers to connect automatically — handy for guest Wi-Fi at home, an Airbnb, a café, or an office reception.

Choose the Wi-Fi mode, type your network name and password, and the code is generated on-device — nothing is ever uploaded. Then pick your colors and brick style, and brickcodes works out the exact plates on a single 32×32 baseplate. Start your Wi-Fi code.

Yes. The symbol is re-encoded cleanly and centered with its quiet zone, so a finished build scans like any printed code — as long as the pieces and baseplate have enough contrast. brickcodes warns you if a color pair is too low-contrast to read reliably.

Leave the password blank and the code is generated for an open network, so scanning connects without asking for one. If your network does not broadcast its name, tick hidden — the code then tells the phone to look for the SSID explicitly, which it will not find on its own otherwise.

A Wi-Fi QR code stores the network name and password as readable text. That is how the standard works — any scanner can read them back out. It is the right trade-off for a guest network on a shelf or a café wall, and the wrong one for a network you would not want a visitor to write down. Many routers let you run a separate guest SSID, which is the safer thing to encode.

Your credentials are never sent anywhere by brickcodes — the code is generated in your browser, and the only copy is the one you build.
