Class 3 Digital Signature for signNow
Award-winning eSignature solution
What a class 3 digital signature is
A class 3 digital signature is a high-assurance digital signature used to verify identity and protect document integrity. It relies on public key cryptography, where the signer uses a private key to create the signature and others use the matching public key to verify it. In U.S. workflows, signNow applies this through secure signing sessions, audit trails, and tamper-evident records that show who signed, when they signed, and whether the document changed after signing.
Why it matters for enforceability
It helps organizations document signer identity, preserve evidence, and support enforceability under ESIGN and UETA. In signNow, that reduces manual handling, speeds approvals, and creates a record that can be reviewed if a signature is challenged.
Frequent implementation pain points
Identity proofing can be too weak if the workflow relies only on email access or a shared inbox. Certificate or key management becomes harder when users switch devices without a controlled provisioning process. Audit evidence can be incomplete if teams export signed files without preserving the full event history. Retention gaps can appear when signed records are stored outside the system of record or deleted too early.
Where class 3 signatures fit
Real estate
Real estate teams use class 3 digital signatures for lease agreements, rental applications, and closing packets.
Regulated records
Healthcare and finance teams use them for consent forms, approvals, and regulated records that need stronger identity evidence.
People who benefit most
A NetSuite operations leader at Xerox uses signNow to route the right documents to the right approvers with integration-driven control. That matters when class 3 digital signatures must fit structured enterprise workflows, not just one-off signing requests. A founder at Martin Properties uses signNow to execute property documents online with compliance and mobile access in mind. That profile fits lease, closing, and authorization workflows where signer identity, timing, and document integrity all matter.

Core capabilities and benefits
signNow supports controlled signing workflows that emphasize identity, integrity, and traceable document handling for regulated and routine business use.
Identity proofing
A secure signing flow captures signer intent and preserves a verifiable record for later review.
Integrity protection
Tamper-evident records show whether the document changed after signing, which supports dispute review.
Audit trail
Audit trails record timestamps, actions, and delivery events for a clearer evidence chain.
Mobile access
Mobile signing lets users complete approvals on desktop or phone without changing the record structure.
Reusable templates
Templates reduce repeated setup work for recurring agreements, forms, and approval packets.
Role control
Access controls help limit who can send, sign, and manage sensitive documents.
How the signing flow works
The signing process follows a simple sequence that verifies the signer, captures the signature, and preserves the record.
Open document: The signer opens the document in a secure session. Verify signer: signNow verifies identity with the selected authentication method. Sign document: The signer applies the signature and submits the record. Seal record: signNow seals the file and stores the audit trail.
Quick setup steps
Use a short setup sequence to move a document from draft to signed record with less manual coordination.
Prepare file:
Create the document and prepare signature fields. Assign signer:
Choose the signer and set access controls. Send request:
Send the request through signNow. Track completion:
Review completion status and archive the record.
Recommended workflow setup
A controlled setup helps keep identity checks, record retention, and access handling aligned with regulated signing needs.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP with ID verification |
| Signature type | Digital signature with certificate-backed integrity |
| Audit trail | Full event log with UTC timestamps |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Supported platforms and devices
signNow works across major desktop browsers and mobile operating systems, with secure transport over TLS 1.2 or TLS 1.3 for web sessions.
Desktop browsers Chrome, Firefox, Edge, and Safari Operating systems Windows, macOS, iOS, and Android Mobile access signNow mobile apps on iOS and Android
For regulated deployments, managed devices, SSO provisioning, and controlled access policies matter more than the device itself. Teams should confirm browser support, mobile app access, and any certificate or retention requirements before rollout.

signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. For HIPAA workflows, a BAA is required, and the signed record should be retained for 6 years under 45 CFR 164.530(j)(2).
signNow supports ESIGN and UETA workflows with tamper-evident records. If a document must meet 21 CFR Part 11, use controls for unique user identification, timestamps, and retained history, and validate the system for the regulated process.
signNow offers HIPAA support with a BAA. The platform should be configured with access controls, audit logging, and encryption at rest, because HIPAA Security Rule safeguards still apply to PHI workflows.
The Business plan is priced at $8/user/mo billed annually. Business Premium adds bulk send, and Enterprise adds advanced signer authentication and integrations. Site License is usage-based for high-volume deployments.
signNow records signer actions, timestamps, and document history. If a signature is challenged, the audit trail helps show who signed, when they signed, and what changed after signing.
signNow supports mobile signing on iOS and Android, plus desktop browsers. If a signer cannot complete a session, confirm browser compatibility, network access, and whether the document requires a stronger authentication method.
