Cl@ve and Digital Certificate

Electronic identification systems: how to get them and what each one is for.

Electronic Identification Systems in Spain

To interact with the government online, you need to identify yourself. Spain has several systems:

Cl@ve

Unified state system offering two levels:

  • Cl@ve PIN: temporary single-use code. Valid for one-time procedures.
  • Cl@ve Permanente: fixed username and password, with SMS verification. For recurring procedures.

How to register: in person at a registration office (INSS, AEAT) or by video call.

Digital Certificate (FNMT)

Issued by the Royal Mint. The most comprehensive:

  • Electronic signature with full legal validity
  • Access to all government services
  • Installed in your browser or on a cryptographic card

Process: request on the FNMT website, verify identity in person, download the certificate.

Electronic ID (DNIe)

Your ID card has an integrated digital certificate chip. You need:

  • Compatible card reader
  • DNIe software installed
  • The PIN given when you renewed your ID
