## How do I make a QR code for my Wi-Fi?

Type the network name and password above, pick the security type and download the code. When someone scans it with their phone camera, the phone offers to join the network. Nobody has to type or spell out the password.

1.  Find the network name (SSID) and password. They are often printed on a sticker on the router, or listed in your phone’s Wi-Fi settings.
2.  Choose the security type. WPA covers WPA, WPA2 and WPA3, which is almost every router. Use None only for an open network.
3.  Tick **Hidden network** if your router does not broadcast its name.
4.  Download the PNG for a sign or a screen, or SVG for print, and test it with a phone before you put it up.

## How do guests use it?

They open the camera and point it at the code. On an iPhone, a “Join network” banner appears. On Android, the camera or Google Lens shows a button to connect. Nobody needs an app.

## Where should I put it?

-   **A guest network is safer.** Most routers can run a separate guest network. Share that one, so guests cannot see your own devices.
-   **Somewhere only guests see.** Anyone who can scan the code can join, so a frame in the living room is better than a window facing the street.
-   **Big enough to scan from a seat.** For a table card, 3 to 5 cm (about 1.5 to 2 in) works. For a wall sign, go bigger.

## What is inside a Wi-Fi QR code?

A short line of text in the format phone cameras look for. Some characters would break it, such as a semicolon in a password. The tool puts a backslash before them for you.

## Questions

How does a Wi-Fi QR code work?

It holds your network name, password and security type in a standard format that phone cameras understand. When someone scans it, the phone offers to join the network. Nobody has to type.

Do iPhones and Android phones both read Wi-Fi QR codes?

Yes. The camera app on iPhone (iOS 11 and later) and on Android phones offers to join the network when it sees a Wi-Fi code.

Is my Wi-Fi password safe here?

Your browser makes the code, and the password never leaves your device. The tool never saves it, not even in your browser’s storage. Anyone who can scan the printed code can join, so put it where only guests will see it.

Which security type should I pick?

WPA covers WPA, WPA2 and WPA3 networks, which is almost every home and office router. Pick WEP only for very old routers, and None for an open network without a password.

What if my network is hidden?

Tick “Hidden network”. The code then tells phones to look for the network even though it does not announce its name.

Does the code stop working if I change my password?

It keeps the old password, so make a new code when you change it. The code itself never expires.
