This is the fourth article from the series focused on the FIDO keys from a couple of manufacturers.
Recently I have received a small package with IDmelon Reader for tests.
I was really surprised about the small form factor size of the USB device and very curious about the functionality of this solution

About IDmelon

A small introduction of the vendor according to the official webpage

IDmelon is a Startup Company that was founded in January 2020. But the company’s existing experience and products are the results of more than five years of hard work and expertise in Bluetooth and FIDO Technologies.
IDmelon is the fruit of a technology acquisition of a Startup Company called Vancosys Data Security Inc., whose main focus has been on researching and developing Bluetooth and FIDO2 based authentication products since 2016. The company’s goal is to facilitate the implementation of passwordless authentication solutions to improve the security of websites and applications. And our focus now is on making a unique and creative FIDO2 Security Key product.

IDmelon is a member of the Microsoft Intelligent Security Association.

LAB details

In order to do the tests for this article, I have created a dedicated user called passwordlesstester in my lab.

In my lab, I have created a dedicated group called Passwordless which is used for FIDO2 Security Key authentication method.
All the tests were made using IDmelon Reader device.

IDmelon Reader could work in 3 modes:

  • Smartphone BLE reader mode – led blinks in white
  • FIDO2 mode – led blinks in green
  • Paired Smartphone mode – led blinks in blue

Switching between the modes is very simple – just press the button for 3 seconds and then wait 15 seconds for a change.

Sounds interesting? Let’s move on.

IDMelon Reader as a FIDO2 device

Configuration process looks almost the same as for other vendors:

  1. Plug in the device to USB port
  2. Select proper device mode by pushing the button for 3 secconds and changing LED to green. – this step is revelant for other vendors
  3. Configure Sign-in method
  4. Use 🙂

Application Setup

Before using the physical device we have to install the application on our mobile phone.
Depending on the mobile OS version we can use Android and iOS.

After the application installation, we need to run it and then click getting started button.

Choosing app from desktop
Getting started with the application

On the Getting Started screen you have to provide an email address that will be used with the application.

Providing email address

You will be informed that verification mail was sent, let’s check the email for the verification code.

Verification email confirmation

After clicking OK and Next, you will be moved to the next screen where you simply click Activate with a code

Choosing the mode of confirmation

So let’s switch to email and open the new message from IDmelon

Email check

Copy the six digits code and provide it to the application

IDmelon verification mail
Providing the verification code

Provide your Personal Information and click Create

Account confirmation

On the next screen, you will be asked about activating your security key on the phone – of course, Approve.
Now you should see a screen with confirmation that we managed to setup the solution on our mobile phone

Alright now we need to switch to our IDmelon Reader device and change mode to Paired Smartphone mode (LED blinks blue). Just press the button for 3 sec and that is all.

The next step is to log on here and add a new security key

Choosing key type

After choosing the key type we will have some useful information and browser acceptance

And finally, information that we can ‘touch’ security key

Here we need to take configure our phone (the one with IDmelon app installed) to be a security key.
Just put it on the IDmelon Reader device and follow the steps.


You can check if the account was added to the app by going into the Registered Accounts tab

All accounts configured within the app
All security keys configured with the app

So now we are configured and our phone works as a security key

Account security configuration.

From now every time when we will need to log in to this account we have to put our phone on the IDmelon Reader.


As you can see there is another player on the authentication field who can help you with the security of your accounts.

IDMelon can work in 2 main modes:

  • For individual users – those steps were described in this article
  • In shared device mode – this topic will be describe soon during the article update.

Test devices were provided by IDmelon Technologies Inc.
