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

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

The signature will allow you to sign in all those applications that are necessary.

The authentication will allow you to authenticate yourself for all the procedures you need to consult.

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