A physical dongle adds a single point of failure. A Multikey Emulator allows you to create a digital backup. If the original is lost or fried by static discharge, you can restore the emulator from a file in minutes.
Before implementing a Multikey emulator, even for legitimate backups, consider these risks: multikey usb emulator

Instead of having physical keys, it stores pre-programmed sequences in memory and plays them back at high speed. A physical dongle adds a single point of failure
