What is a Wi-Fi QR code?

A Wi-Fi QR code encodes your network name (SSID), password, and security type into a standard QR format. When someone scans it with a modern Android or iPhone camera, the phone prompts them to join the network automatically. No app is needed — the native camera on both platforms handles it out of the box.

Where this is useful

  • Home: Print a QR code and stick it next to your router so family and visitors can connect without asking for the password each time.
  • Office or coworking space: Put a QR code card on desks or in the meeting room to make guest Wi-Fi access quick and smooth.
  • Cafe or shop: Frame a printed QR code at the counter instead of writing the password on a chalkboard that anyone can photograph.
  • Events: Include a QR code on printed programmes or table cards so attendees can get online immediately.

Step-by-step: generate a Wi-Fi QR code

  1. Open the QR code generator. Go to the QR Code Generator on LightDarkTools. No login is needed and nothing is sent to a server.
  2. Select the Wi-Fi tab. The generator supports several QR types. Choose Wi-Fi from the type selector at the top.
  3. Enter your network details. Type in your Network Name (SSID) and Password. Then select the correct Security type — most modern routers use WPA/WPA2.
  4. Customise if needed. You can change the QR foreground and background colours, adjust the error correction level, or add a logo if you want a branded result.
  5. Download the QR code. Click Download PNG to save the image. Print it, add it to a sign, or share it digitally — whatever suits your use case.
Security note: Your Wi-Fi password is encoded inside the QR code image. Anyone who scans the code gets access to your network, so only share or print it in places where you control who can scan it. If your password ever changes, generate a new QR code.

What security type should I choose?

Most home and office routers built in the last several years use WPA2 or WPA3. If you are unsure, check your router's admin page or the label on the back of the device. The options in the generator match the standard Wi-Fi QR specification, so choosing the wrong security type means phones will not connect after scanning.

  • WPA/WPA2 — most common for home and small office routers.
  • WPA3 — newer routers may use this; check your router settings to confirm.
  • WEP — an older, less secure standard. Avoid if possible.
  • None / Open — for public hotspots with no password.

Does the tool store my Wi-Fi password?

No. The QR Code Generator on LightDarkTools runs entirely in your browser. Your network name and password are used locally to generate the QR image and are never sent to any server.

Will it work on all phones?

Wi-Fi QR codes are supported natively on Android 10 and later and on iOS 11 and later. On these versions, simply open the camera app, point it at the code, and tap the notification to connect. Older devices may need a third-party QR scanner app.
