For the generation of the qualified digital certificate.

To complete the certificate generation and document signing process, a one-time password (OTP) is sent to the user, enhancing the security of the process.

Signature completed with certificate

The signed document includes the Qualified Signature with the Digital Certificate, complying with all legal guarantees and security standards.

Qualified electronic signature

QES is a digital signature created using signals unique to the signatory, supported by a qualified digital certificate compliant with Regulation (EU) 910/2014 Art. 24.1d for electronic transactions in the European market and generated with a qualified signature creation device via a European CA.

This signature, which is covered by the eIDAS Regulation, provides the highest level of legal security. It has a legal validity equivalent to a handwritten signature. In disputes, it will be considered as evidence without the need for expert evidence.

Financial services around the world rely on QES in a wide variety of use cases, and its introduction as part of the onboarding process reliably confirms the identity of the signatory and protects both users and businesses against forgery or counterfeiting.

Issuance of qualified digital certificate

The process of issuing these certificates follows the guidelines of the eIDAS Regulation, ensuring high security and legal validity. Issued by accredited Trust Service Providers supervised by European authorities, these certificates allow for the unequivocal identification of the holder. In Spain, the Ministry of Economic Affairs and Digital Transformation oversees these providers.
