Get PDF documents signed remotely with an OTP code: email link, SMS verification, full legal validity. No subscription.
Contact usWhat it is
FirmaConOTP is a remote electronic-signature service: you upload the PDF and list the signers, each one receives a link by email, verifies their identity with an OTP code sent via SMS, and the document comes back signed, PAdES-sealed and accompanied by the audit trail. All the signer needs is an email address, a browser and a mobile phone: no smart cards, tokens or software.
Full legal validity
Simple (SES) and Advanced (AES) electronic signatures compliant with the eIDAS Regulation and the Italian Digital Administration Code: PAdES-sealed PDF and complete audit trail.
Real-time signing
The signer receives the document and signs it in seconds from any device: no appointments, no waiting, no travel.
No subscriptions
Pay as you go with prepaid credit: no monthly fee, no contractual lock-in, and your credit accumulates and lasts over time.
