Digital Signature for SignNow Workflows
Award-winning eSignature solution
What a digital signature is
A digital signature is a cryptographic method for signing electronic records that ties the signer’s identity to the file and helps detect tampering after signing. In a U.S. setting, SignNow supports this workflow with templates, mobile apps, audit trails, and signer authentication tools. The result is a signed record that can support ESIGN and UETA enforceability when intent, attribution, and record retention are properly handled.
Why digital signatures matter legally
A digital signature helps prove who signed, when they signed, and whether the record changed afterward. Under ESIGN and UETA, that evidence can support enforceability for most U.S. business records, while clear audit trails and retention practices improve defensibility in disputes and compliance reviews.
Core features for digital signatures
SignNow combines signing, workflow control, and compliance-oriented recordkeeping so teams can complete documents with less friction and clearer evidence.
Legally binding

Mobile signing
Collect signatures from desktop or mobile devices, including iOS and Android apps, when signers are away from the office or working remotely.
Audit trail
Track each action with timestamps, signer identity details, and document history so the record supports ESIGN, UETA, and legal review.
Signer authentication
Add stronger access controls with 2FA, SMS OTP, and ID verification when the transaction needs higher signer assurance or regulated handling.

How the signing flow works
The process follows a simple sequence from document preparation through signing, completion, and retention, with each step recorded for traceability.
Prepare: Upload the document or choose a template, then place signature and field locations where each signer must act. Deliver: Send the request by email, signing link, mobile app, or kiosk mode, depending on the workflow. Sign: Each signer reviews, completes, and signs with the chosen authentication method and intent to sign. Archive: SignNow stores the completed file, audit trail, and timestamps for later retrieval, export, or retention.
Recommended workflow settings
Set each workflow control to match the record type, retention rule, and signer assurance level needed for the transaction.
| Setting | Recommendation |
|---|---|
| Authentication method | Email link with 2FA |
| Signature type | eSignature with audit trail |
| Audit trail | Enabled for every document |
| Document retention | 6 years for HIPAA |
| Encryption | AES-256 at rest |
Sending and signing methods
- Use the web app when you need a full desktop workflow for preparing documents, assigning fields, and sending requests to internal teams or external signers who can complete everything in a browser.
- Use the mobile app when signers need to review and sign away from a desk. iOS and Android apps help field teams, sales staff, and managers finish documents on the move.
- Use kiosk mode for one device shared by many signers, such as reception areas, job sites, or event check-in points, where the same tablet must handle repeated signatures securely.
- Use shareable signing links when a document must move quickly without a direct email invite. Links help with broad distribution, but the document still keeps its audit trail and signer attribution.
Platform and device requirements
SignNow works in modern browsers and mobile apps, with secure connections over TLS 1.2 or TLS 1.3 on supported desktop and mobile devices.
Browser support Chrome, Firefox, Safari, Edge Desktop systems Windows, macOS, Linux Mobile access iOS, Android mobile apps
For regulated or enterprise use, browser and device management matters because administrators may rely on SSO, API access, and controlled provisioning. SignNow’s paid plans and Site License can fit managed environments where audit trails, encryption, and access policies need to stay consistent across Windows, macOS, iPhone, iPad, and Android deployments.

Who benefits most from digital signatures
Different business sizes use digital signatures in different ways, from one-person offices to multi-department teams with structured approval rules.
A solo real estate practice can use SignNow to send leases, disclosures, and rental agreements electronically, reducing in-person meetings and keeping document turnaround visible from a single dashboard. A healthcare group can collect patient signatures on intake forms and consent records with HIPAA-oriented controls, while keeping the BAA, audit trail, and document history aligned for record review. An enterprise operations team can route contracts, approvals, and internal forms through templates, delegated sending, and SSO-enabled provisioning so large-volume workflows stay consistent across locations and departments.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.

Frequently asked questions about digital signatures
These answers cover signNow features, plan limits, and U.S. compliance points that often matter during signature workflows.
SignNow Business includes legally binding eSignatures, templates, mobile apps, and audit trails. If a signer cannot finish, check whether the document uses a valid email or signing link, then resend from the request panel. ESIGN and UETA focus on intent and attribution, not a specific file format.
The Business Premium plan adds bulk send and kiosk mode, while the Business plan does not list bulk send in the verified plan summary. If you need to send one document to many recipients, confirm the plan before starting the workflow. The audit trail remains available in both plans.
For HIPAA workflows, SignNow is compliant when a BAA is in place. If a healthcare signer sees a compliance concern, verify the account is configured for PHI handling, encryption at rest with AES-256, and access controls that meet HIPAA Security Rule requirements under 45 CFR 164.312.
If a PDF signature field is not filling correctly, check that the file is a standard PDF and not a flattened image. SignNow supports templates and fillable forms, so the issue is often document preparation rather than the signing engine itself. Recreate the field if needed.
If a signature must stand up to FDA review, the relevant standard is 21 CFR Part 11. SignNow supports audit trails, timestamps, and 2FA, which align with that framework, but validation remains the customer’s responsibility. Regulated records may need documented procedures and retention controls.
On the Site License plan, SignNow adds SSO, full API access, and HIPAA or 21 CFR options as add-ons. If those controls are missing, the account may be on a lower tier. Review the plan name first, then map the required compliance or integration feature set.
