QR code for WiFi
Let guests join your network by scanning once—no spelling out SSIDs or passwords across a noisy room.
How WiFi QR codes work
The QR payload follows the common WiFi format: security type, SSID, and password. iOS and Android camera apps typically recognize it and prompt to connect. Always test with a phone that has not joined the network before.
Security tips
Use WPA/WPA2 for typical guest networks. Rotate passwords if a QR code is displayed publicly and you worry about outdated photos. For open networks, understand that anyone within range can connect.

FAQ
What details are required for a WiFi QR code?
You need SSID, password, and security type (usually WPA/WPA2). All three must match your router settings.
Do iPhone and Android both support WiFi QR?
Most modern devices do, but behavior differs by OS version and camera app. Test with real target devices first.
What happens after I change the WiFi password?
The old QR code will no longer connect correctly. Generate a new one and replace printed copies.
Can I create a QR code for open WiFi?
Yes, but open networks are less secure. For businesses, a protected guest network is usually safer.
Why does scan sometimes fail to connect?
Common causes include wrong SSID, wrong password, wrong security type, or device network policies.
