The systems accepted by the VÀLid are explained below. The authentication process can be carried out, in general, with idCAT Mobile, Digital certificates and Cl@ve. However, each public administration user of the VÀLid system can decide whether to show all systems or only some depending on the procedure (For example, only show "Digital Certificates" to consider them a more secure system for that specific procedure). If you do not see one of the systems and you have doubts about it, you will have to check with the organization with which you are doing the online management.

These are the systems that the VALID system has classified and integrated:

idCAT Mobile

It is a solution from the AOC Consortium, aimed at user authentication and electronic signature, aimed at the citizen and based on the sending of single-use passwords to their mobile phone, as an alternative to the use of digital certificates. The system offers a medium level of security in accordance with what is established by the National Security Scheme.

If the idCAT Mobile is not displayed in the procedure you are carrying out, it means that for this procedure the specific administration does not accept this method.
