Secure Signer Identity for SignNow
Award-winning eSignature solution
What secure signer identity means
Secure signer identity is the process of verifying that the person signing a document is the intended signer. It works by combining identity checks, access controls, and a signed record that links the signer to the document and the signing event. In signNow workflows, this can include email access, SMS OTP, ID verification, or other authentication methods, plus a tamper-evident audit trail. The result is a clearer record of who signed, when they signed, and what they signed.
Why secure signer identity matters
It reduces signing disputes, supports faster approvals, and helps preserve enforceability under ESIGN and UETA when attribution, intent, and record integrity are documented.
Common identity verification issues
Weak authentication can make it hard to prove the signer was the intended person. Poor audit records leave gaps in who accessed, viewed, or completed the document. Shared inboxes and reused credentials can blur attribution across multiple signers. Missing retention controls can make it difficult to produce records during a dispute.
Who uses secure signer identity
Where it fits
Secure signer identity supports teams that need stronger proof of who signed, especially for regulated or high-value documents.
Document types
It applies to leases, consent forms, contracts, claims, approvals, and records that need attribution, intent, and traceability.
People who rely on secure signer identity
Real estate operations leaders at firms like Martin Properties use secure signer identity to route leases, disclosures, and tenant forms with a clearer record of signer intent, mobile access, and completion history across office and field workflows. NetSuite operations directors at manufacturers such as Xerox use secure signer identity to match the right signer to the right document format, preserve approval history, and keep contract execution aligned with ERP-driven business processes.

Core features that support signer identity
signNow supports identity-focused signing workflows with controls that help document who signed, how they signed, and what evidence remains afterward.
Identity proof
Link signer actions to a documented identity check, so each signature has a clearer attribution trail for review, audit, or dispute resolution.
Audit trail
Capture timestamps, IP data, and event history in one record, giving teams a more complete signing timeline.
Authentication options
Use SMS OTP, ID verification, or other controls to raise assurance for sensitive agreements and regulated workflows.
Tamper evidence
Apply tamper-evident sealing so later edits are easier to detect and challenge in court or compliance reviews.
Record control
Keep signed records organized for retrieval, retention, and export when legal, HR, or compliance teams need them.
Cross-device signing
Support mobile and desktop signing without losing the identity record that ties the signer to the document.
How secure signer identity works
The signing flow is sequential, so each step adds evidence that the signer was identified and the record stayed intact.
Send request: The signer receives a secure signing request. Verify signer: Identity is verified before access continues. Apply signature: The signature is attached to the record. Record activity: The system logs the event for review.
Quick setup steps for signer identity
Use a short setup sequence to match the verification level to the document and keep the resulting record easy to retrieve.
Set verification:
Choose the identity check for the document risk. Prepare request:
Add the signer and delivery method. Check evidence:
Review the audit trail after signing. File record:
Store the completed record for retention.
Recommended signer identity setup
Use a setup that matches the document’s risk level, preserves evidence, and supports retention requirements for regulated records.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP for higher assurance |
| Signature type | Electronic signature with audit trail |
| Audit trail | Enable time-stamped event logging |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform requirements for secure signing
Secure signer identity works in modern browsers and mobile environments that support encrypted connections, document viewing, and signing workflows across desktop and handheld devices.
Desktop browsers Chrome, Firefox, Edge, and Safari Operating systems Windows, macOS, iOS, and Android Connection security TLS 1.2 or TLS 1.3
For regulated use, teams should also confirm device management, access policies, and record retention rules before rollout. signNow supports browser-based signing across Windows, macOS, iOS, and Android, which helps organizations keep the signing experience consistent while preserving the evidence needed for compliance reviews and audits.

Real-world examples of signer identity controls
These examples show how identity checks, routing, and recordkeeping work together in signNow-based document workflows.
Real estate operations
A real estate team needed a clearer identity record for lease execution across mobile and office workflows.
- Martin Properties used online signing for document execution.
- Mobile access helped keep approvals moving.
The workflow kept lease execution organized, with a stronger record of who signed, when they signed, and which document version was completed. That helped reduce back-and-forth and made completed records easier to retrieve for internal review.
ERP operations
A manufacturing operations leader needed the right signatures on the right documents inside NetSuite-connected processes.
- Xerox aligned signatures with ERP-driven document routing.
- Integration helped match formats to business rules.
The integration-centered workflow improved document routing and preserved a more complete signing history for downstream teams. That made it easier to connect approvals to business records without losing the identity evidence attached to the signed file.

A careful setup makes the identity record easier to defend, easier to audit, and easier to keep aligned with policy requirements.

FAQ about signer identity and compliance
These answers focus on identity verification, evidence, and plan limits that affect regulated and high-value signing workflows.
If a signer cannot pass SMS OTP, check the phone number, delivery settings, and network access. signNow supports multiple authentication methods, and stronger workflows can use ID verification when the document risk requires more assurance.
If a HIPAA workflow needs a BAA, confirm the account is on a plan that supports HIPAA use and that the agreement is in place before handling PHI. HIPAA also expects audit controls, unique user identification, and integrity safeguards.
If a document needs 21 CFR Part 11 controls, use a workflow with unique user IDs, secure timestamps, and a retained audit trail. FDA-regulated records also need validated systems and signature-to-record binding for electronic records.
If a signer disputes authorship, export the audit trail and completed PDF together. signNow records time-stamped events that help show attribution, intent, and document history under ESIGN and UETA.
If a team needs bulk sending, use a plan that includes it, such as Business Premium. The Business plan includes core eSignature features, while higher tiers add more workflow options and advanced controls.
If a record must be retained for healthcare compliance, keep it for 6 years from the date of creation or the last effective date, whichever is later, under 45 CFR 164.530(j)(2).
