## What it does

Enter a network name, password and security type and this builds the standard WIFI: payload that Android and iOS understand, then renders it as a QR code. Scanning it joins the network without anyone typing a password, which is what makes it useful for guests, an office wall or a rental. The credentials stay in the page and are never put in the URL.

## Questions

### Does it work on an iPhone?

Yes. The Camera app on iOS 11 and later reads Wi-Fi QR codes directly, with no extra app installed.

### Is it safe to print the password in a QR code?

Treat a printed code exactly like the password itself — anyone who can photograph it can join the network. If you hand one out and later change your mind, change the password.

### Which security type should I pick?

WPA/WPA2 for essentially every modern network, including WPA3 routers that still accept WPA2 clients. Use WEP only for genuinely old hardware, and 'no password' only for an open network.
