OTP Mail Signature

The OTP Mail signature is based on a one-time-password code, generated from the hash of the document to be signed, and sent to the signer’s email address through an email. The verification code generated by Viafirma corresponds to a random algorithm for which the content of the document to be signed (hash) is used, being able to prove that this OTP code corresponds to a specific document and not to another one.
