Advanced signature (AES / eIDAS level 2)

The Advanced Electronic Signature (AES) is the second level of electronic signature defined by the eIDAS regulation. It must be uniquely linked to the signatory, enable their identification, be created with data under their sole control, and make any subsequent modification to the document detectable. Certyneo implements it via strong authentication (email + OTP email/SMS) and a timestamped audit trail. It is suitable for the vast majority of contractual use cases: employment contracts, leases, NDAs, quotes, invoices. See also: AES, SES, QES. Understand eIDAS levels →
