21 CFR Part 11 eSignature for Regulated Workflows
Award-winning eSignature solution
What 21 CFR Part 11 means for eSignature
21 CFR for electronic signature refers to the FDA rule set in 21 CFR Part 11 that governs electronic records and signatures in regulated U.S. industries. It explains when an electronic signature can stand in for a handwritten one and what controls must support it. In practice, the system should verify the signer’s identity, capture a secure audit trail, protect record integrity, and bind the signature to the document so later changes are detectable.
Why 21 CFR Part 11 matters
It matters because FDA-regulated teams need records that are enforceable, reviewable, and easier to manage than paper. Under ESIGN and UETA, electronic signatures can be legally valid, while Part 11 adds the controls needed for regulated records and signatures to support compliance and evidentiary use.
Common Part 11 pain points
Confirming signer identity without creating friction for clinical, quality, or manufacturing teams. Keeping audit trails complete when documents move across departments, devices, or integrations. Aligning retention, access control, and validation with FDA recordkeeping expectations. Preventing edits, exports, or workflow changes from weakening signature integrity.
Who uses Part 11 eSignature
Regulated operations
FDA-regulated teams use eSignature workflows for batch records, SOP approvals, validation records, and controlled forms.
Quality and clinical
Quality, clinical, and manufacturing groups use it for approvals, acknowledgments, and traceable document routing.
Teams that rely on Part 11 workflows
A quality systems manager in a medical device company uses signNow to route SOP approvals, training acknowledgments, and change-control records while preserving auditability and signer attribution across review steps. A clinical operations lead at a life sciences organization uses signNow to collect signatures on study documents, site forms, and controlled workflows that need traceable identity checks and reliable record history.

Core Part 11 capabilities
Part 11 workflows depend on identity, integrity, and traceability. signNow organizes those controls into practical signing and review steps.
Audit trail
Captures signer identity, timestamps, and document actions in a record that supports review, traceability, and regulated recordkeeping.
Tamper evidence
Links the signature to the document so later changes are easier to detect and investigate.
Signer verification
Supports two-factor authentication and controlled access for higher-assurance signing workflows.
Cross-device signing
Keeps approvals moving across desktop and mobile devices without losing the record history needed for compliance review.
Controlled workflows
Helps teams manage controlled documents, approvals, and acknowledgments in one workflow instead of separate paper processes.
Process consistency
Supports validation-oriented processes by keeping signing steps structured, repeatable, and easier to document.
How Part 11 signing works
Part 11 signing follows a simple sequence: send, verify, log, and seal. Each step adds evidence that the record is controlled and traceable.
Send: The signer receives a controlled request and opens the document. Verify: Identity checks confirm the signer before the signature is applied. Log: The system records the event, time, and document state. Seal: The signed file is sealed for later review and retrieval.
Quick setup steps
Use a short setup sequence to keep regulated signing consistent and easier to audit.
Prepare:
Upload the controlled document and define the approval path. Route:
Assign the right signer and required reviewers. Secure:
Set identity checks and access controls before sending. Archive:
Review the completed record and store it with the audit trail.
Recommended Part 11 setup
Use controls that support identity, integrity, and retention for FDA-regulated records and signatures.
| Setting | Recommendation |
|---|---|
| Authentication method | Two-factor authentication |
| Signature type | Electronic signature with intent |
| Audit trail | Enable full event logging |
| Document retention | 6 years (HIPAA 45 CFR 164.530(j)(2)) |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform requirements
Use current browsers and supported operating systems to keep signing, review, and audit access stable across desktop and mobile devices.
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 deployments, managed devices, identity controls, and secure storage matter more than a specific browser choice. Teams should also confirm API access, SSO provisioning, and retention policies before rollout, especially when documents must support FDA review, HIPAA handling, or internal validation records.

Real-world workflow examples
These examples show how regulated and document-heavy teams use signNow to keep approvals traceable and easier to manage.
Operations workflow
A Xerox operations leader needed flexible routing for the right signatures on the right documents.
- NetSuite-connected workflows kept approvals aligned with business systems.
The result was faster routing, clearer document control, and a signing process that fit existing enterprise operations without losing traceability.
Real estate execution
A founder at Martin Properties needed online execution with strong compliance and built-in security.
- Mobile and offline signing helped keep transactions moving.
The workflow supported remote document completion while preserving the record history needed for review, making it easier to manage agreements without paper delays.
Best practices for regulated signing
Part 11 programs work best when identity, retention, and validation are defined before the first regulated signature is collected.
Require stronger signer verification
Preserve the full record history
Validate before rollout
Align retention with policy
Part 11 FAQ and troubleshooting
These answers focus on plan limits, compliance controls, and the signNow features most often used in regulated signing workflows.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. For HIPAA use, a BAA is required, and Part 11 workflows need identity controls, timestamps, and retained document history.
Use the Business Premium or Enterprise plan when you need bulk send, while regulated workflows can still rely on audit trails and signer controls. For higher-assurance needs, the Site License adds SSO, full API access, and HIPAA or 21 CFR options as add-ons.
A Part 11 workflow should keep the audit trail attached to the record, with timestamps, signer identity, and document history preserved. signNow’s audit trail and history features support that evidence chain.
HIPAA use requires a signed BAA, plus encryption, access controls, and audit logging. signNow states HIPAA support with BAA, and the platform also lists SOC 2 Type II and ISO 27001 among its compliance credentials.
For FDA-regulated records, use two-factor authentication, unique user IDs, and controlled access. Part 11 also expects secure timestamps and a record history that shows who signed, when, and what changed.
The Business plan starts at $8/user/mo billed annually. If you need advanced signer authentication, bulk send, or enterprise integrations, review Business Premium, Enterprise, or Site License pricing before rollout.
