Frequently asked questions
- How does a Wi-Fi QR code work?
- It encodes your network name, security type, and password. Scanning it prompts the phone to join the network automatically — no typing the password.
- Is my Wi-Fi password uploaded anywhere?
- No. The code is generated entirely in your browser; nothing is sent to a server.
- Which networks are supported?
- WPA/WPA2/WPA3 (password-protected) and open networks. For hidden networks, mark the network as hidden so devices can find it.
- Can guests still join if I change the password?
- A static Wi-Fi code stops working when the password changes. For a code you can update without reprinting the sign, point a dynamic LumenQR code at a join page instead.
