Configure Required Authentication Methods in Adobe Sign

Set up the appropriate authentication methods before sending documents to ensure the resulting audit trail meets the recipient's compliance standards.

Adobe Sign allows senders to enforce various levels of authentication for signers. To generate an audit report that includes OTP verification, you must enable and configure the specific authentication method prior to dispatching the document.

1
Confirm recipient requirements

Contact the receiving organization to determine their exact audit-trail and authentication requirements, explicitly asking if SMS OTP is a mandatory compliance factor.

2
Configure the authentication method

When setting up your document in Adobe Sign, navigate to the recipient's email field and select the 'Authentication' dropdown. Choose 'Phone' or the corresponding OTP method to require an SMS code before signing.

3
Verify compliance before sending

Consult with your organization's IT administrator or Adobe Sign support to ensure the selected settings will produce an audit report that fully complies with the recipient's standards.

Frequently Asked Questions

What is an Adobe Sign audit trail?

An audit trail in Adobe Sign is a detailed, uneditable log that records the complete history of a document, including when it was created, viewed, signed, as well as the IP addresses and authentication methods utilized by all parties.

Why would an organization reject a signed PDF?

Organizations may reject signed PDFs if the accompanying audit report fails to prove that strict authentication standards, such as two-factor authentication or SMS OTP, were actively enforced during the signing process.

Can I add SMS OTP verification to an existing Adobe Sign document?

No, you must configure the authentication method, including SMS OTP, before sending the document for signature. Once a document is sent or signed, the authentication method cannot be retroactively changed for that specific transaction.

Does WPS Office support PDF document signing?

Yes, WPS Office includes built-in PDF tools that allow users to draw, type, or insert electronic signatures into their documents easily, making it an excellent free alternative for everyday document signing needs.
