How does the Wi-Fi QR code generator work?

The tool encodes your Wi-Fi SSID, password, and security protocol into a standardized URI string (WIFI:T:WPA;S:MySSID;P:MyPassword;;). When scanned with an iPhone or Android camera, the operating system prompts you to join the network without typing the password.

Is my Wi-Fi password sent to any remote server?

No. All tools on RouterIPHub execute 100% locally in your client web browser using vanilla JavaScript. No passwords, IPs, or network names are ever transmitted across the internet.
