• The digital certificates accepted to identify yourself and electronically sign requests and payments are those with a public key which have not been cancelled, and which are supported by @firma, the Higher Council for Electronic Administration's electronic signature validation platform. Details of the certificates which are currently valid can be found on the website: DNI electrónico > Autoridades de validación

    The @firma platform accepts digital certificates that are compliant with the ITU-T X.509 v3 standard, issued by multiple certification service providers. All the providers are registered under the authority registry of the State Secretariat for Telecommunications and the Information Society of the Ministry of Industry, Tourism and Trade, pursuant to Section 30 of Law 59/2003, of 19 December, the Electronic Signature Act.

    Digital user certificates must be installed on the browser or available via a PKCS#11 module installed on the browser (in the case of the eDNI).

    If the certificate you are using for authentication and signature purposes is not a user certificate (there are component certificates, legal entity certificates, etc.) it may be that some of the obligatory personal data (Name, First Surname, NIF) is not filled in, in which case the request will be rejected.

    Electronic DNI

    To use an electronic DNI for authentication and signature purposes when processing certificate requests the citizen must have on their computer a browser, encrypted card reader and operating system which are supported and must also install an encryption module.

    All information of interest and downloads needed to use the electronic DNI, can be found at this link: Electronic DNI (National Identification Card).

    Some procedures require you to provide electronic identification (in the same way that you would also have to provide ID if you were carrying out the procedure in person).

    You can identify yourself electronically using the electronic DNI.

    You can also do so using other electronic certificates issued by the Certification Authorities accepted on this site.
