How to request the digital certificate of the FNMT in any browser

23 mayo, 2021

Recently, the National Currency and Stamp Factory (FNMT) your digital certificate request procedure has slightly changed, launching a tool for the generation of keys that allows any of the main browsers compatible with the most used operating systems (Windows 10, macOS and Linux) are supported in the process of requesting or renewing the digital certificate.

This opens up new options for us, like trying to store certificates in all installed browsers and not only in the one from which we carry out the process, as well as automatically generate backups thereof. Let’s see how to request it:


Steps to follow

The first step will be to download and install the new FNMT-RCM Configurator software, which we will find in its corresponding version of the web in several versions: for 32 and 64-bit Windows, for 32 and 64-bit Linux (both in RPM and DEB packages) and for macOS. Choose the appropriate version for your computer and start downloading it.

Once the software is downloaded, installation in Windows is very simple: there is nothing to configure or options to decide on, everything is summarized in the typical ‘Next> Next …’ process until we are informed that it is properly installed.

The next step will consist of open our favorite browser and access with him at the Electronic Headquarters of the FNMT. There, we will access the Certificates section and choose the kind of certificate that we are looking for (‘Natural Person’ or ‘Representative’).

Once chosen, we will enter the corresponding section and click, in the left column, on ‘Get Software Certificate’:

After that, we will click indistinctly in ‘Request Certificate’ (left column) or in ‘Request via Internet for the Certificate’ (body of the article):

In both cases, we will be sent to a form in which we will have to fill in our ID, first surname and e-mail address:

Note: now it is important that, once completed, do not click directly on the ‘Send request’ button, but on the link ‘Click here to consult and accept certificate issuance conditions’. This will cause the aforementioned conditions to be displayed, after which we must check the acceptance box of the same and -now- in ‘Send request’.

Web6

At this point, if we are using Internet Explorer or Firefox 68, then we can only wait for it to arrive by mail our application number, associated with the DNI.

But If we are using any other browser, it will notify us that the web is trying to start the application that we installed before, which we will accept by clicking ‘Open’ in the dialog box.

After that, the Configurator will only show a window in which we will be asked to enter a password twice, whose function is to protect the certificate keys. Once entered, the number of the certificate request, associated with our ID, will be sent to the email address that we wrote before.

Next, we will have to go through the offices to prove our identity, and after that the Administration will be in charge of send us another email, with a code that we will use to download the certificate (at which point we will have to enter the password again). Once downloaded (and the conditions accepted), the installation process will begin.

But remember: the browser and operating system from which we make the request must be the same in which we install then the certificate: forget, in that intermediate period of time, to carry out any kind of software update or change, because if the metadata does not match the process will not be able to be completed. Once installed, yes, we will have no problem exporting it.
