PassWordless Authentication with Fido 2 Keys – Part 3 – IDMelon

As you probably have seen in my previous posts, security keys are here to stay. They can be used as a separate authentication method beyond secondary authentication. There are multiple manufacturers that help us in our passwordless journey, for that reason, to the realization of this post, I used a IDMelon security key that also supports FIDO2

The main difference here with other security key, is that IDMelon uses is own security authenticator app which I will review during this post.

How it works

First of all, you need to download the app to your smartphone, which can be done in a very simply steps and then plug the security key and install the software.

Once you have done this, you can pair your smartphone and the key:

So, once you have done, you’re ready to go to and configure the security key for your user account. I am not going to cover the process because it has been done in previous post, and the process is straightforward (PassWordless Authentication with Fido 2 Keys – Albandrod’s Memory ( PassWordless Authentication with Fido 2 Keys – Part 2 – Albandrod’s Memory (

If you look deeper into this application, you can check the current plan that you have with the security key, and most important, the activity log of the security key, which I think is great!

Now, if we look into the AAD Sign in we are able to review the sign in information regarding the security Key:

To conclude, I found that IDMelon keys are a great product, because not only provides a password less journey to the users, also provides a simply way to manage the activity of the security token and also the signin process.

Thanks to IDMelon for providing this token to test out their solution

till nex time!
