Digital Signature Define for SignNow Compliance Guide

Award-winning eSignature solution

What a digital signature is

A digital signature is a cryptographic way to sign an electronic document and prove who signed it and whether the file changed after signing. It uses public key infrastructure, or PKI, to create a unique signature tied to the signer and the document. In practice, the signer authenticates, the system hashes the file, and the signature is attached to that hash. When someone opens the record later, the signature can be verified against the document and the signer’s certificate.

Why digital signatures matter

Digital signatures reduce paper handling, speed approvals, and create stronger evidence of intent. Under ESIGN and UETA, they can be legally enforceable when the signer’s identity, consent, and record integrity are preserved.

Why teams look for DocuSign alternatives

Common digital signature pitfalls

Signer identity can be disputed if authentication is weak or poorly documented.
Documents can lose evidentiary value when audit trails are incomplete or altered.
Teams often mix digital signatures with simple e-signatures and miss compliance needs.
Retention and access controls can fail when records are stored outside policy.

Real estate

Real estate teams use digital signatures for leases, disclosures, and closing packets.

Healthcare

Healthcare organizations use them for intake forms, consent records, and HIPAA workflows.

People who benefit most

Operations leaders at property firms use signNow to route leases, add tenant signatures, and keep mobile-friendly records moving across offices and field teams.

Identity checks

Applies signer authentication options that help confirm identity before the signature is accepted.

Tamper evidence

Stores signed records in a tamper-evident format that helps protect document integrity over time.

Connected systems and workflows

signNow connects signature workflows to business systems so documents, approvals, and records stay in the tools teams already use.

How the signing flow works

A digital signature follows a clear sequence from document delivery to final verification and storage.

Send request: The signer receives a secure request and opens the document.
Verify identity: The signer authenticates before accessing the signing step.
Apply signature: The system records the signature and locks the file state.
Save record: The completed record is stored with verification data.

Quick setup steps

Use a short workflow to prepare, send, and store a signed document without extra steps.

Prepare the file:
Upload the document and place signature fields.
Set the route:
Choose the signer order and authentication method.
Start the workflow:
Send the request and monitor responses.
Save the result:
Download or store the completed record.

Setting	Recommendation
Authentication method	SMS OTP for routine approvals
Signature type	Digital signature with PKI
Audit trail	Full time-stamped event log
Document retention	6 years for HIPAA records
Encryption	TLS 1.2/1.3 and AES-256

Platform and device requirements

signNow works in modern browsers and mobile apps, with secure transport over TLS and support across desktop and phone workflows.

Desktop browsers Chrome, Firefox, Safari, and Edge
Operating systems Windows, macOS, iOS, and Android
Mobile access signNow mobile apps on iOS and Android

For regulated use, managed devices, access controls, and retention policies matter as much as browser support. Teams should confirm account permissions, API access, and any BAA or compliance requirements before deployment.

ERP operations

A NetSuite operations director needed the right signatures on the right records.

signNow matched signatures to ERP formats.
Integration helped keep approvals in sequence.

The integration supported structured approvals and cleaner record handling, which helped the team connect signature steps to business systems without manual rework.

Best practices for reliable signing

A stable signing process depends on identity, record quality, retention, and access control working together.

Match authentication to risk

Use stronger authentication for contracts, healthcare forms, and financial approvals. Match the signer verification method to the document risk, and keep the evidence needed to show who signed, when they signed, and how the record was protected.

Define signature standards

Separate digital signatures from simple drawn signatures in your policy. Define when PKI-based signing is required, when an electronic signature is enough, and how the audit trail should be stored for later review.

Set retention by record type

Keep retention rules tied to the document type and regulation. For HIPAA-covered records, retain signed documents for 6 years under 45 CFR 164.530(j)(2), and make sure access controls stay in place during storage.

Control routing and access

Review templates, signer order, and permissions before sending. Standardized routing reduces errors, while role-based access helps prevent the wrong person from receiving, editing, or approving a document.

FAQ and troubleshooting

These answers focus on plan limits, compliance needs, and record handling issues that affect digital signature workflows.

signNow Business includes legally binding eSignatures, audit trails, templates, mobile apps, ISO 27001, SOC 2, and GDPR support. If a workflow needs HIPAA, a BAA is required before handling PHI.

signNow supports audit trails that record signer activity, timestamps, and document history. For stronger evidentiary support, keep the completed record and audit trail together, especially for ESIGN and UETA transactions.

Business Premium adds bulk send, while Enterprise adds advanced signer authentication and formula fields. If a workflow needs higher-volume routing, the plan choice should match the document process, not just the signature count.

The Business plan starts at $8/user/mo with annual billing. If you need SSO, full API access, or HIPAA and 21 CFR Part 11 add-ons, the Site License is the plan to review.

Under ESIGN and UETA, a signature is valid when it can be attributed to the signer and the record shows intent. If attribution is disputed, stronger authentication and a complete audit trail matter most.

For healthcare records, HIPAA retention is 6 years from the date of creation or the last effective date, whichever is later. Keep signed records encrypted and access-controlled during that period.
