QR code for guest Wi-Fi
Writing the Wi-Fi password on a sticky note is the most common approach, and the least convenient. A Wi-Fi QR code lets a guest connect with a single scan, no typing required and no risk of misreading a complex password. The WIFI format encodes the network name (SSID), security type, and password directly in the QR: the native Camera app on iOS and Android offers to connect automatically. One important point: here, your password is encoded locally in your browser and sent to no server at all. It never leaves your device.
Customize QR
A QR code carries redundancy: the reader rebuilds modules that are stained, creased or hidden. The higher the level, the more damage it takes, but the bigger the code gets. At the same print size, each module therefore becomes smaller.

Fill in the form to generate your QR code.

1. Enter your network name and password
The SSID is your Wi-Fi network name as it appears in the list of available networks. For security type, choose WPA/WPA2 if your router uses a password. The vast majority of home routers do. If you have an open guest network with no password, choose 'none.'

2. Print and display at the entrance
Print the QR large (at least 2×2 inches for a table tent) and laminate if the environment is damp: a coffee shop, bar, or Airbnb bathroom. Add a short label: 'Scan to join the guest Wi-Fi.' Keep the background light for good contrast.

3. Test on both iOS and Android
On iPhone (iOS 11+), the Camera app recognizes the WIFI format and offers to join the network without opening any other app. On Android (8.0+), the QR is scanned with the native Camera or Google Lens. Confirm the connection works on both platforms.

4. Reprint if you change your password
The QR encodes the password as it is at generation time. If you change your Wi-Fi password (a good annual practice), regenerate and reprint. There's no third-party service to update. Just come back here and generate a new one.
Does my Wi-Fi password go through any server?
No. The QR is generated entirely in your browser: your password is not sent anywhere. Some online generators store SSIDs and passwords on their servers: a real security risk. Here, no data leaves your device.
Can this Wi-Fi QR code expire?
No, it cannot expire. It encodes your SSID and password statically. As long as your network name and password don't change, the QR works indefinitely. The generators that expire are those that use a redirect through their own server. That is not the case here.
WPA vs WPA2: which do I pick?
For the Wi-Fi QR format, WPA and WPA2 use the same encoding: just choose whichever matches your router setting. Most home routers use WPA2. If you're unsure, check your router's admin panel or look at the network's security info in your device's Wi-Fi settings.
Can I use this for an open network with no password?
Yes. In the generator, select security type 'none' and leave the password field blank. The QR will connect directly to your open network. Note: an open network is accessible to anyone within range. Reserve this for dedicated guest networks only.
