Why add a dual authentication layer to signing
Dual factor authentication improves signer identity assurance, reduces fraud and unauthorized access, and strengthens compliance posture for regulated workflows such as healthcare and finance.
Common implementation challenges
- User friction and resistance can increase if authentication steps are poorly explained or optional recovery paths are missing.
- Device compatibility issues arise when signers lack smartphones or have limited cellular access for SMS verification.
- Operational complexity grows with multiple authentication modes, complicating admin setup and policy enforcement.
- SMS delivery failures and SIM swap vulnerability may weaken security if SMS is the only second factor.
User profiles: roles and responsibilities
IT Administrator
The IT Administrator configures authentication options, manages SSO and MFA policies, monitors access logs, and ensures platform integrations meet organizational security standards. They coordinate with compliance and operations to maintain consistent enforcement across signNow accounts and document workflows.
Compliance Officer
The Compliance Officer defines acceptable authentication levels for different transaction types, documents retention requirements, and evaluates audit trails for regulatory adherence. They review reports, approve retention policies, and validate that signNow settings align with ESIGN, UETA, and specific industry rules.
Typical teams and roles that use this setup
Organizations with sensitive agreements or regulated data routinely adopt dual factor authentication to protect signature workflows and verify identities prior to execution.
- Legal and contracts teams handling binding agreements and signature authentication.
- Healthcare providers and administrators managing PHI and HIPAA-related consents.
- Human resources teams for onboarding documents and background check authorizations.
The approach is relevant across small legal teams to large enterprises and is commonly chosen where auditability and signer verification are required for compliance.

Key features that support secure dual factor signing
MFA Enrollment
Self-service MFA enrollment lets users link authenticator apps or phone numbers and manage secondary verification methods while administrators can enforce enrollment policies and recovery options to balance security with usability.
Custom Authentication
Admins can require different authentication methods for specific document templates or signer groups, allowing stronger checks for high-risk transactions and lighter checks where appropriate to reduce friction.
Comprehensive Audit Trail
Detailed logs capture authentication events, IP addresses, timestamps, and verification methods to support dispute resolution and regulatory reviews while preserving an evidentiary record for each signed document.
Compliance Controls
Configuration options align signing workflows with ESIGN and UETA requirements and can be tailored to meet HIPAA-minded handling of PHI or industry-specific record retention and access policies.

- This reduces fraudulent consents and unauthorized access
Resulting in a stronger audit record for HIPAA compliance and reduced downstream risk.

Leading to clearer evidentiary trails for regulatory reviews and dispute resolution.
Best practices for secure and user-friendly dual factor signing
FAQs About use double factor authentication setup dual factor authentication and sign
- What if a signer does not receive an SMS code?
Confirm the phone number is entered correctly and that carrier delivery is available in the recipient’s region. Offer an alternate verification method such as an authenticator app or email verification, and consider extending retry limits while maintaining security controls to prevent abuse.
- Can I require different authentication for different documents?
Yes. Configure authentication policies by template or document type so high-risk forms require stronger verification while low-risk documents use standard identity checks. This lets administrators balance security and usability per transaction class.
- How does dual factor authentication affect signature validity?
Dual factor authentication strengthens the identity evidence associated with a signature but does not change ESIGN or UETA legal frameworks. It improves non-repudiation and can make signatures easier to defend in disputes when combined with a complete audit trail.
- Are SMS codes secure enough for regulated workflows?
SMS provides convenience but carries known risks such as SIM swap attacks. For regulated workflows or high-value transactions, prefer authenticator apps, hardware tokens, or certificate-based methods to meet stronger security requirements.
- How do I manage lost or changed secondary devices?
Implement recovery procedures that include identity verification by support or admin, alternative verification channels like email, and allow administrators to revoke or reset registered second factors to maintain account security.
- What audit information is stored for authentication events?
signNow captures event timestamps, authentication method used, IP address, and verification outcomes in the document audit trail. This information supports compliance reviews and dispute resolution and can be retained per your configured retention policy.
