Technical Implementation

The application is built using:

Golang: For core functionality and networking
Fyne.io: For cross-platform GUI
Go-Keyring: For secure credential storage
Network Detection: Custom implementation for captive portal detection

Project Goals

This project aims to solve the frustration of repetitive manual logins to Fortinet networks, particularly in educational and corporate environments. The application runs quietly in the background, ensuring users maintain their network connection without interruption.
