Seconds Factors
At the time of mentalizing to perform the signature, the user may require second factors claimed or not by PortSigma.

Normally the most usual thing is that you do not need anything extra to be able to make the signature of the document.
Java security
When entering through a digital certificate, java can block it if it does not recognize the PortaSigma application as secure.
