What Is an Electronic Signature?

An electronic signature is information used to indicate a person's intent to sign a document electronically. It can be used for many everyday documents and digital workflows where an electronic signature is accepted.

Depending on the use case and applicable laws, an electronic signature may have different legal requirements. For documents requiring a specific type of legally recognized digital signature or certificate-based signature, use an appropriate qualified or certified signing solution.

Electronic Signature vs. Digital Signature

An electronic signature generally refers to an electronic indication of a person's intent to sign. A digital signature, on the other hand, typically uses cryptographic technology and a digital certificate to verify the signer and help protect document integrity.

If your document requires certificate-based authentication, identity verification, or a legally specific digital-signature standard, make sure you use a signing service that provides those features.
