By navigating to the link you have received and clicking the access button, you will be required to identify yourself with a valid electronic certificate recognised by the administration. How to know if your certificate is valid?

Check the documentation you are going to sign by clicking on the documents you have received and if you agree, click Sign. Otherwise, click Return.

You will be asked again for your certificate to carry out the signature and the result will be displayed.
