How to Make a WiFi QR Code for Guests
By QRVane · Updated
Open the WiFi QR code generator, enter your network name (SSID), password and security type (WPA/WPA2 for most home routers), and download the code.
Print it and place it where guests can see it. Modern iPhone and Android cameras offer to join the network when they scan it.
Because the password is stored inside the code, anyone who scans it can join: only display it where you'd be happy to share the password, and change the password and regenerate the code if it leaks.
