Digital Signature with Digital Mobile Key

Last Updated: 03/03/2022

Fénix has available in the system the possibility of performing the digital signature of documents (staves) using the potential of the Digital Mobile Key.

The use of the Digital Mobile Key and digital signature presupposes its prior activation and this process is not performed in Fénix.

This document presents and explains from scratch the procedure of activating the Digital Mobile Key and digital signature, as well as examples of how to test the digital signature in Fénix and also the demonstration of the signature of a staff in the process of final evaluation of a Curricular Unit.

If you have already activated the Digital Mobile Key and digital signature you do not need to redo these steps.

It is recommended that before performing the first signature of an agenda always perform the signature test to confirm that the digital signature process ran to the end without difficulties.

In addition to the previous recommendation, it is essential not to start this process at the same time that it is intended to make the digital signature of an agenda. There may be difficulties inherent to the external services responsible for the Citizen Card/ Digital Mobile Key, so it is recommended to deal with this phase in advance.

Digital Mobile Key

To activate the Digital Mobile Key must have with you the following elements
– Citizen card- Card


With a card reader connected to your computer, follow the following steps:

Signature of an Agenda

The signature of an agenda using the Digital Mobile Key has no changes regarding the functionality that was used within the Teaching portal in the management and administration section of the Curricular Unit.

The launch of the staff is done in the Final Evaluation feature as usual.

  • After the launch of the agenda, either by importing an excel file or manually launching, the agenda is ready to be confirmed and signed;
  • By selecting Confirm and sign digitally , the process of signing the staff is started. This process is identical to what was described in the Test Signature section, and a window is displayed with the preview of the staff and then all other iterations of validation and confirmation of the digital signature of this document.
  • Select Start signature to start the digital signature.
  • After completing all the steps for the validation and processing of the digital signature, please note that you need to finish in the last window presented to you.

    This action is very important and indispensable because although the document is already signed, if you do not select Finish fénix does not complete the process and the agenda is not confirmed;
  • Finally, the agenda is confirmed and digitally signed.
