I need to generate a WiFi QR sign without sending network credentials to a server.

Generate a WiFi QR code sign locally so your network name and password never leave your device. This lets guests connect quickly while keeping credentials private and under your control.

This feature lets you create a WiFi QR code sign entirely on your device, without transmitting your SSID or password to any server. You enter your WiFi details (network name, password, and security type) and the QR code is generated locally for immediate use. The resulting QR code can be displayed on-screen or saved for printing to create a physical sign for guests. Because generation happens offline or locally, it reduces privacy and security concerns associated with cloud-based QR generators. It also improves reliability in low-connectivity environments, since no internet connection is required to produce the QR sign. This is useful for homes, small offices, cafés, events, and short-term rentals where many people need quick access to WiFi. It helps minimize manual password sharing and reduces typing errors for guests. The local-only approach supports safer workflows for organizations that have policies against sharing credentials with third-party services. Overall, it combines convenience (scan-to-join) with stronger confidentiality (no credential upload).
