A tiny IP KVM adds robust HTTPS and multi-factor security to remote PC control

The Radxa Linkr is a compact, credit-card-sized hardware device designed to act as a secure IP-based Keyboard-Video-Mouse (KVM) switch. It connects to a target computer via HDMI and USB, allowing remote control and monitoring over a network through a standard web browser, with support for modern security features like HTTPS, two-factor authentication (2FA), and integration with Tailscale, a zero-trust networking platform.

This device is aimed at IT administrators, developers, and power users who need to manage headless servers, embedded systems, or remote lab equipment. The inclusion of HTTPS and 2FA directly addresses common security weaknesses in budget or DIY KVM solutions, which often transmit credentials and screen data unencrypted. While the initial setup revealed some browser-specific quirks, the core promise is a portable, secure remote management tool that doesn't require installing software on the target machine, making it a practical upgrade for remote tech support and infrastructure management.
