What Is A Dongle Key
And How Does A Dongle Work?

This article is all about Dongles. You’ll find answers to the top questions people have about USB Security Dongles. So, if you’ve ever asked any of the following questions:

Then this post will be a dream come true…

What Is A Dongle Key?

Often referred to as a “Dongle” or a “Key”, they function as software protection dongles. Dongles are a piece of hardware that, when connected to computers (or other electronic devices), permit specified software to function or allow for content decoding.

Dongles allow access limitations to certain software based on who possesses the dongle.

Programmed with product keys or other such cryptographic security protection, dongles utilize electrical connections to external computers/device ‘buses’.

How Does A Dongle Work?

Dongles are beloved software protection hardware. Dongles are two-interface security tokens utilizing transient data flow.

Transient data flow occurs thanks to a “pull communication” which reads security data stored on the Dongle, itself. Softwares that use Dongles will either run in restricted mode or not at all if a Security Dongle is not
plugged in.

What Is Dongle Used For?


What is the purpose of a dongle? As outlined above, it is a piece of hardware that limits access to software. Basically, once a security dongle is set-up with a specific software, only people who have access to the dongle can access the software.

There’s often more expensive piracy prevention software included since you not only have to have the software installed, but the physical device (the Dongle), as well.

While software protection Dongles are a great security tool, issues arise if you have more than one person needing access to software that utilizes a Dongle.

For example, if you gave someone a copy of the software, and they don’t have the physical security Dongle, the software is inaccessible.

However, there is an easy and reliable solution that allows you to expand access to software using software protection Dongles!

That solution is the software called Donglify.
