Use Double Factor Authentication with SignNow
What use double factor authentication setup dual factor authentication and sign means in practice
Why implement dual-factor authentication for signing
Dual-factor authentication reduces account compromise and signature repudiation risk by requiring a second verification factor, improving identity assurance and supporting regulatory expectations for sensitive transactions in many U.S. industries.
Common implementation challenges
- User adoption friction if enrollment is poorly communicated or second-factor options are limited.
- Integration gaps when legacy systems do not support modern authentication protocols like TOTP or FIDO2.
- Operational overhead from managing lost tokens, phone number changes, and helpdesk requests.
- Balancing security with accessibility for signers who lack smartphones or consistent mobile service.
Typical user profiles for dual-factor signing
IT Administrator
An IT Administrator configures authentication policies, integrates identity providers, and deploys two-factor requirements across signing workflows. They maintain system settings, troubleshoot enrollment issues, and ensure authentication aligns with corporate security standards and directory services.
Compliance Officer
A Compliance Officer defines verification requirements and documents controls to meet regulatory obligations. They review audit trails, confirm retention policies, and evaluate whether dual-factor authentication and provider evidence satisfy legal standards like ESIGN and UETA.
Organizations and roles that commonly use dual-factor signing
Typical adopters include corporate legal teams, HR departments, finance organizations, and IT security groups that require stronger signer verification for contracts and approvals.
- Legal and contracts teams managing enforceable agreements and compliance records.
- Human resources processing employment documents and sensitive personnel data.
- IT and security teams enforcing access controls and monitoring authentication events.
These workflows are most valuable where signature authenticity, access control, and auditability matter, such as finance, healthcare, and higher education settings.
Choose a better solution
Key features to look for when setting up dual-factor signing
Multiple factor options
Support for TOTP apps, SMS, email, and hardware tokens gives organizations the flexibility to match security needs to user capability while maintaining a consistent signing experience across channels.
Configurable policies
Policy controls that allow administrators to require second-factor authentication for specific templates, user groups, or document types help enforce security without applying blanket restrictions to all transactions.
Audit and evidence
Detailed authentication events stored with each transaction—timestamps, IP addresses, and verification method—provide the auditability required for compliance and dispute resolution.
Fallback options
Secure fallback or recovery procedures, such as administrator-assisted enrollment or temporary codes, reduce helpdesk burden while maintaining control over identity recovery.
How dual-factor signing operates during a signing session
-
Initiate: Sender creates and routes the document to signer.
-
Authenticate: Signer enters password and completes second factor.
-
Authorize: System verifies both factors and allows signing.
-
Record: Audit trail records authentication and signature events.
Quick setup steps for enabling dual-factor authentication in signing flows
-
01Plan: Define required second-factor methods and user groups.
-
02Configure: Enable MFA options in the eSignature admin console.
-
03Enroll: Register user devices and distribute enrollment instructions.
-
04Monitor: Review logs and adjust policies based on events.

Device and platform considerations for dual-factor signing
Ensure supported platforms and device types meet your chosen second-factor methods before rolling out dual-factor signing across users.
- Desktop browsers: Modern versions supported
- Mobile platforms: iOS and Android compatible
- Authenticator apps: TOTP compatible
Confirm that browsers and mobile OS versions used by your organization support required cryptographic functions and that fallback policies exist for users without compatible devices.
Industry examples using dual-factor signing
Healthcare onboarding
A hospital collects patient consent and insurance forms electronically while requiring a second factor via authenticator apps to confirm identity.
- Enforces strong signer verification.
- Reduces fraudulent consent and protects PHI.
Resulting in auditable records and stronger compliance posture for HIPAA-covered workflows.
Higher education enrollment
A university admits students and issues financial aid forms with two-factor verification using SMS or email plus a password.
- Verifies applicant identity at signing.
- Prevents unauthorized changes and identity fraud.
Leading to clearer audit trails and reduced administrative disputes over enrollment documentation.
Best practices for secure and convenient dual-factor signing
Common problems and troubleshooting for dual-factor signing
- Signer does not receive SMS codes
Verify the phone number on file and request the user confirm carrier support; check for network issues and ensure sender numeric IDs are not blocked. If SMS delivery is unreliable, offer an authenticator app alternative or administrator-assisted verification to complete the transaction securely.
- Authenticator app codes rejected
Confirm device time synchronization and that the correct shared secret was registered. Re-enroll the authenticator if codes continue to fail, and provide clear steps for secure re-enrollment to avoid bypassing required authentication controls.
- User lost access to second factor
Use documented recovery procedures such as administrator identity verification, secondary verified methods, or temporary one-time codes. Maintain logs of recovery steps to preserve an audit trail for compliance purposes and minimize abuse of recovery processes.
- Integration with single sign-on fails
Check SAML or OAuth configurations, certificate validity, and attribute mappings. Ensure the identity provider sends required claims for MFA and that the eSignature platform trusts the identity provider for second-factor assertions.
- Audit records incomplete or missing
Confirm audit logging is enabled for authentication events, that retention policies are configured, and that storage systems are healthy. If logs are missing, escalate to platform support with transaction identifiers and timestamps to reconstruct verification evidence.
- High helpdesk volume after rollout
Improve enrollment communication, publish concise self-service guides, and stage rollout to pilot groups. Monitor support tickets for common issues and update policies or training to reduce repetitive incidents while preserving required security controls.
