What is a Dongle?

A dongle is a small device that plugs into a computer’s USB drive. Dongles offer different functionality, such as providing mobile internet access, speeding up data transfer, running secure software, or connecting multiple devices to the computer.

With a WiFi dongle, you can access the internet in places like the beach.

In short, the term “dongle” is defined as any small device that plugs into the Universal Serial Bus (USB) or other computer port, no matter what it does. These devices are usually used to provide some function that is not built into the computer itself. This includes adding memory, providing Bluetooth® and WiFi® connections, and adding adapters so that other devices can be connected. Mobile broadband USB modems are often referred to as “mobile dongles”.

In industries that frequently use protected software, the term is still used primarily for security devices.

Why is a dongle called a dongle?

Nobody knows where the word “dongle” originated. According to Oxford University Press, publisher of the famous English Dictionary, “dongle” is of uncertain and anonymous origin.

How does a security dongle work?

The software sends an encrypted request to the security dongle for a validation key, which is also encrypted.

There are several types of dongles.

This means that in order to break the dongle, a hacker must first break the encryption.

Older dongles were usually plugged into the computer’s serial port and used to protect software already loaded on the computer. During charging, the software would check for the presence of the dongle, and if it didn’t find it, it wouldn’t charge. This system was vulnerable because a programmer could alter the software to not look for the dongle or think it was present when it was not.

An even more secure approach stores encrypted bits of the software in the dongle itself, which the program requests when it needs them. In this scenario, even if a hacker tricked the software into thinking the device was present, the software could not run because essential parts of its code would be missing.

Did you know?

A dongle is any small device that plugs into a computer’s USB port.

Dongles can provide Internet access, fast file transfer and secure software.

Some dongles connect multiple devices to a computer.

Nobody knows where the word “dongle” comes from.

How do other types of dongles work?

Non-security dongles work by including virtually all necessary hardware and software on the device itself.

Make sure you buy the right type of dongle for your needs, as there are many types.

Can a dongle be used as wi-fi?

Yup. Wi-Fi dongles, also called a USB wireless adapter or USB wifi adapter, include a network adapter that allows a computer to connect to the Internet.

Although the computer must have the correct settings to make the broadband connection, the device contains the technology that allows the connection to be made.

What is a Wireless Sync Dongle?

A wireless sync dongle is a dongle that communicates with a device, often a fitness device, and transfers its data to a computer.

What is a Bluetooth dongle?

A Bluetooth dongle connects a Bluetooth-enabled device, such as a mouse or keyboard, with a computer.

What problems do the dongles have?

Common dongle problems report to security and the use of locked software. They are also easily lost.

A few software companies have attempted to introduce dongle security with their consumer-oriented software without success, even though consumers are often familiar with USB technology.

Technology changes and new operating systems and hardware become more commonplace, older software that requires the device may no longer be usable.

Another common problem is that people may need to use more than one type of locked software at a time and the computer may not be able to accommodate all the different devices at once. Most dongles take up a port, and do not allow other devices to be plugged into them; a computer that only has two or three USB ports, for example, may already have a mouse, camera, or other device attached, leaving no room for anything else.

In addition, dongles are easily lost or damaged. Specialists such as video editors or audio engineers may be willing to put up with the inconvenience, but the average computer user is usually not.

To cope with these problems, some companies specialize in emulators that attempt to convince the computer that the dongle is present. These emulators are not always legal, however, as they are specifically designed to get around security issues.

When a person buys a piece of software, what he or she is really buying, most of the time, is a license to use the software. With that license, the user typically agrees to certain conditions, and using an emulator may break those rules.

If the person who purchased the software did so legally, and does have the dongle/or if that piece of hardware no longer works correctly, it may be legal to use an emulator instead in some circumstances.

Are there dongle alternatives?

There are alternatives to using a dongle for security purposes, although they are not always as reliable.

Some programs have key codes that must be entered when the software is first installed; others only allow the program to be installed once.

In some cases, the computer running the software must have an internet connection so that it can regularly connect to the manufacturer’s servers to confirm who is using the program. As with dongles, each of these security measures can cause problems for the user if they do not work correctly or if the software needs to be transferred to a new computer. In addition, nearly all such methods have been cracked.

A skilled hacker can trick a computer into falsely verifying that a security dongle is installed.
