# WiFi QR Code Generator

A WiFi QR code stores your network name, security type, and password so a phone joins the network by scanning instead of typing the password.

A WiFi QR code is a plain-text instruction to a phone's WiFi settings. It carries
the network name, the security type, and the password, formatted so the camera
app can join the network without anyone typing anything.

## How to
1. Type your network name exactly as it appears in phone WiFi settings, including capitals.
2. Choose the security type. Almost every modern router uses WPA.
3. Enter the password. Leave it blank only if the network is genuinely open.
4. Download the PNG for screens or the SVG for printing, then print it at 4 cm or larger.
5. Test it with two phones — one Android, one iPhone — before putting it on the wall.

## WiFi security types and QR support
| Security | Payload value | Scans on modern phones | Notes |
| --- | --- | --- | --- |
| WPA / WPA2 / WPA3 | WPA | Yes | Use this unless your router is very old. |
| WEP | WEP | Mostly | Deprecated and insecure; replace the router. |
| Open network | nopass | Yes | No password field is written into the code. |

## FAQ
### Does a WiFi QR code expose my password?
Yes. The password is stored in plain text inside the code, so anyone who scans it can read it. Use a guest network for a code you put on a wall.

### Do iPhones and Android phones both support WiFi QR codes?
Yes. iOS 11 and later joins from the camera app; Android 10 and later joins from the WiFi settings screen or a camera app that supports it. Older Android phones may need a separate QR scanner app.

### How big should I print a WiFi QR code?
At least 4 cm across for a table tent read at arm's length. The rule of thumb is one tenth of the scan distance.

### Can I change the network later without reprinting?
No. The password is baked into the code, so changing the network means printing a new one.
