The T-CAT (personal on card) from the adaptation of its profile to the eIDAS regulations on 05/09/2018, includes two certificates:

  • T-CAT (Signature) “SIG”
  • T-CAT (Authentication) “AUT”

The signature will allow the signature to be made in all those applications that are necessary.

The authentication one will allow you to authenticate for all those procedures you need to consult.

You can check how to differentiate the certificates in each case through the following link .
