Identity Authentication for Electronic Signatures
Security is the top priority when agreements carry risk. Foxit eSign helps you confirm the right signer is accessing the right document by offering flexible identity authentication options you can apply per recipient and workflow. Choose lightweight verification for everyday agreements, or step up assurance with multi-factor and knowledge-based methods when confidence matters most.

Flexible Signer Verification Options
Identity authentication should match the agreement—not the other way around. These capabilities help you tailor signer verification to risk level, reduce access mistakes, and maintain strong evidence throughout the signing process.
Multi-Factor Authentication (MFA)
Require identity confirmation across two or more devices before document access.
Two-Factor Authentication Options
Send one-time codes via email, mobile, or phone for secure entry.
SMS Document Link Delivery
Add a text-based step for controlled access when workflows require it.
User-Defined Access Code
Create a custom code you share out-of-band for added recipient verification.
Knowledge-Based Authentication (KBA)
Validate signers with questions only they should answer before opening documents.
Configurable Authentication Levels
Select authentication per recipient during sending or online form security setup.
Use Cases for
Signer Authentication
Any time identity confidence matters, authentication options help protect the transaction. Teams can apply flexible verification to common agreements without turning signing into a bottleneck.
Add MFA, 2FA, or KBA to strengthen signer identity verification for key documents.
Use access codes or 2FA to reduce risk on employee agreements and notices.
Apply recipient authentication to confirm access and reduce unintended forwarding.
Increase identity confidence for patient-facing approvals in regulated environments.
Protect onboarding packages when vendor access must be verified before signing.
Set authentication levels for recipients when forms are shared broadly.


Stronger Identity Assurance for
Regulated Industries
Regulated teams often need stronger identity assurance and clear controls. These industry scenarios highlight where authentication options like MFA, KBA, and higher-assurance pathways support governance and compliance goals.
Use KBA and multi-factor options to support stricter identity verification expectations.
Align signing workflows with compliance modules and higher-assurance verification requirements.
Apply authentication controls for sensitive patient documents and protected information.
Reduce risk on permission forms and records where identity and access matter.
Strengthen access controls for forms requiring traceability and accountability.
Use compliance-driven options and higher-assurance signatures where eIDAS applies.
