eSigning FAQs

How does an electronic signature differ from a digital signature?

All digital signatures are electronic signatures, but not all electronic signatures are digital signatures. Digital signatures verify a signer’s identity using their unique digital certificate, which a signer can purchase from a trusted vendor. Whereas eSignatures usually identify signers through audit trails (which track users’ IP addresses and activity within a document), digital signatures identify signers through encryption and digital certificates. You can think of them as the digital version of a notarized signature.

What is an electronic signature?

An electronic signature (also known as “eSignature” or “online signature”) is the electronic equivalent of signing a document with a handwritten signature.
