Digital Certificate and Signature for SignNow
Award-winning eSignature solution
What a digital certificate does
A digital certificate and signature combines cryptographic identity proof with an electronic signature workflow. In practice, a certificate issued through PKI binds a signer or organization to a public key, while the signature shows intent and protects the document from unnoticed change. signNow supports this workflow with audit trails, signer authentication, and secure record handling for U.S. business use under ESIGN and UETA.
Legal value under U.S. law
Digital certificate and signature matters because it binds identity to a record, speeds remote transactions, and creates evidence that supports enforcement under ESIGN and UETA when intent, consent, and record integrity are preserved.

How the signing flow works
The signing process is sequential: prepare the file, deliver it, capture intent, and preserve the record afterward.
Prepare: Start with a document configured for signing fields and recipient order. Deliver: Send it through SignNow with the chosen authentication method. Sign: Signer intent is captured when the document is completed. Store: The final file and audit trail remain available for review.

Key features of digital certificate and signature
The main value comes from stronger identity proof, clearer records, and a signing process that holds up better in regulated work.
Audit trail
SignNow creates a traceable record of signer activity, timestamps, and document actions. That record helps teams review who signed, when they signed, and how the file moved through the workflow.
Signer verification
Signer authentication options help match the level of identity proof to the document’s risk. Two-factor checks, SMS OTP, and ID verification are useful when a simple email link is not enough.
Reusable templates
Templates keep recurring forms consistent, which reduces manual setup and routing errors. They also help teams reuse approved fields, signer order, and language across similar agreements.
Mobile signing
Mobile access supports signing when people are away from a desk. That matters for field teams, healthcare staff, and remote customers who need to finish documents on phones or tablets.
Record retention
Retention and export tools help preserve the signed record after completion. Keeping the final PDF, the audit trail, and any related metadata together supports later review and internal recordkeeping.
Compliance support
Compliance-ready workflows support U.S. legal and industry requirements, including ESIGN, UETA, HIPAA, and 21 CFR Part 11 where applicable. That makes the output easier to defend and store.
How to send a document for signature
A short workflow works best when the document is prepared once and the signing path is defined before the first request goes out.
Prepare the file:
Choose the document and prepare fields for signatures, dates, and any required attachments. Route to signers:
Add recipients and set the signing order if more than one person must sign. Set controls:
Select authentication and signing settings that match the document sensitivity and compliance needs. Complete and file:
Send the request, then monitor completion and download the signed record with its audit trail.

Who benefits most from digital certificate and signature
Different business types need different levels of control, but all of them benefit from faster routing, traceable signatures, and cleaner recordkeeping.
A solo law practice can use SignNow for NDAs, engagement letters, and client authorizations that need fast turnaround without adding staff. Shared templates and delegated sending help a small office keep intake moving while preserving a simple review path for each file. A mid-sized healthcare provider can collect patient consent, onboarding forms, and release documents with controlled access and a BAA-backed workflow. That setup helps staff manage PHI carefully while keeping signed records available for audit and retention requirements. An enterprise operations team can standardize contracts, approvals, and vendor packets across departments. Shared templates, admin controls, and delegated sending reduce routing errors, while the audit trail helps legal, finance, and compliance teams review activity after completion.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
Best practices for signed records
Good recordkeeping starts before the signature is applied and continues through storage, export, and retention review.
Match authentication to risk
Standardize recurring templates
Set retention early
Limit record access
FAQs about digital certificate and signature
These questions focus on identity proof, compliance, storage, and document limits that affect real signing workflows.
SignNow supports ESIGN and UETA workflows with audit trails, signer authentication, and document history. If a record needs stronger identity proof, use two-factor authentication or ID verification before sending, and keep the completed PDF with its trail for later review.
HIPAA workflows require a BAA, unique user identification, access controls, and audit controls under 45 CFR §164.312. SignNow supports HIPAA compliance with a BAA requirement, so healthcare teams should confirm the agreement is active before handling PHI.
For sensitive records, use SignNow plan features that support stronger controls, such as advanced signer authentication in Enterprise or SSO and API access in the Site License. Match the plan to the document risk before rolling out the workflow.
If a signed file needs long-term defensibility, export the audit trail and store it with the final PDF. For regulated records, keep retention aligned with the applicable rule, such as 6 years for HIPAA-covered documents.
Not every document can be handled electronically. Wills, certain court orders, some family law documents, and some real-estate deeds may require wet ink or notarization under state law, so check the governing rule before relying on an eSignature alone.
If a signer cannot complete the process on a phone, use SignNow mobile apps or send a link that opens in a browser. Mobile-created eSignatures are valid under ESIGN and UETA when the signer intended to sign and consented electronically.
