FDA 21 CFR Part 11 Electronic Signature for Regulated Records
Award-winning eSignature solution
What FDA 21 CFR Part 11 electronic signature means
FDA 21 CFR Part 11 electronic signature is an electronic signature used on records that fall under FDA predicate rules, such as GMP, GCP, or device quality requirements. It lets a regulated organization sign electronically while preserving identity, intent, and record integrity. In practice, the system links the signer to the document, captures a secure audit trail, records the date and time, and uses access controls and authentication to show who signed, what was signed, and when it happened.
Why it matters for regulated records
It reduces paper handling, speeds approvals, and supports enforceable records under ESIGN and UETA when identity, intent, and retention are documented. For FDA-regulated workflows, it also helps preserve evidence needed for inspection and dispute review.
Implementation pain points
Weak signer authentication can make it harder to prove who actually approved the record. Missing audit trail details can leave gaps in the signing history and change log. Poor access control can allow unauthorized users to view, route, or sign records. Unclear retention rules can cause signed records to be deleted before inspection or litigation.
Who uses it in regulated work
Regulated teams
Regulated teams use it for controlled approvals, release records, and signature-ready forms.
Document types
It applies to batch records, validation documents, SOP approvals, and clinical or quality sign-offs.
People who benefit most
Quality operations leads in pharmaceutical manufacturing use signNow to route batch release approvals, deviation sign-offs, and SOP acknowledgments with controlled access, audit trails, and signer identity records that support FDA inspection readiness and internal review. Clinical operations coordinators in biotech and medical device teams use signNow for protocol acknowledgments, site documents, and study approvals, where fast turnaround matters and the record must still show intent, timing, and traceable signer actions.

Core features for regulated signing
The main value is controlled signing with traceable identity, preserved record history, and a workflow that fits regulated review steps.
Signer traceability
Links each signature to a named user, time, and document event so regulated teams can show who approved what and when.
Audit trail
Captures a secure history of views, clicks, signatures, and changes to support review, investigation, and inspection workflows.
Access control
Uses access controls and authentication steps to reduce unauthorized signing and protect regulated records from misuse.
Record integrity
Keeps the signed file tied to its signature so later edits are easier to detect and challenge.
Flexible signing
Supports mobile and desktop signing so approvals can move without paper while preserving the same record controls.
Workflow consistency
Helps teams standardize approval paths for quality, clinical, and compliance documents across departments and locations.
How the signing flow works
The process is sequential: open the record, verify the signer, capture the event history, and preserve the completed file for review.
Open document: The signer opens a controlled document and reviews the request. Verify identity: The system verifies identity before the signature is accepted. Log activity: The record captures time, signer data, and action history. Seal record: The completed file is sealed for later review and export.
Quick setup steps
Use a short setup sequence to move from document upload to a signed, retained record.
Upload file:
Upload the regulated document to a controlled workflow. Assign signers:
Add required signers and approval order. Configure controls:
Set authentication and reminder rules. Send for signature:
Send the document and monitor completion. Archive record:
Store the completed record with its history.
Recommended workflow settings
A controlled setup should pair strong identity checks with retained records, encryption, and a clear signing history.
| Setting | Recommendation |
|---|---|
| Authentication method | Two-factor authentication |
| Signature type | SES with identity controls |
| Audit trail | Enabled for every action |
| Document retention | 6 years (HIPAA 45 CFR 164.530(j)(2)) |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform and device requirements
signNow works across major browsers and mobile operating systems, with TLS-protected sessions and app-based signing on iOS and Android.
Browser support Chrome, Firefox, Edge, and Safari Operating systems Windows, macOS, iOS, and Android Mobile access Mobile apps on iOS and Android
For regulated deployment, managed devices, SSO provisioning, and controlled access policies matter more than a specific browser choice. Teams should also confirm retention, export, and authentication settings before rolling out FDA-signable workflows across departments.

Real-world workflow examples
These examples show how signNow fits document-heavy teams that need speed, traceability, and controlled approvals.
Enterprise operations
A NetSuite operations leader needed faster approvals across internal teams and customers without losing document control.
- Kodi-Marie Evans at Xerox used signNow with NetSuite.
- The workflow matched the right signatures to the right documents.
The result was a more flexible approval process with traceable routing, better document matching, and less manual follow-up. That matters in regulated environments where the signing path, document version, and signer identity all need to stay aligned.
Healthcare workflow
A healthcare founder needed online execution for patient-facing forms while keeping security and compliance visible.
- John Butler at Fertility Centers of Illinois used signNow.
- The team relied on API support and responsive service.
The outcome was faster form turnaround with a controlled signing process that fit healthcare record handling. For FDA-related or HIPAA-related records, that combination of identity checks, audit history, and retention support is often the key requirement.
Best practices for regulated signing
Good implementation depends on access control, validation, and record retention, not just the signature itself.

FAQ and troubleshooting
These answers focus on plan limits, compliance controls, and the features most often checked during regulated implementation.
signNow Business starts at $8/user/mo billed annually. For FDA-regulated use, confirm the workflow includes authentication, audit trails, and retention controls before production rollout.
signNow supports 21 CFR Part 11 controls, including 2FA, session timeouts, e-signature timestamps, and document history retention. Those controls help support regulated recordkeeping, but your SOPs and validation still matter.
For HIPAA workflows, signNow can be used with a BAA. HIPAA also requires unique user identification, audit controls, integrity controls, and retention of signed records for 6 years under 45 CFR 164.530(j)(2).
If a signer cannot complete authentication, check the method you enabled. SMS OTP, ID verification, and other stronger methods may be required for higher-assurance workflows, while simple email links may not fit regulated approvals.
If the audit trail looks incomplete, confirm that the workflow captured signer identity, timestamps, IP data where available, and document history. A defensible record needs a complete, tamper-evident event log.
If you need bulk sending, that is included in the Business Premium plan. Enterprise adds advanced signer authentication, and Site License adds SSO, full API access, and HIPAA or 21 CFR options as add-ons.
