Identity Authentication FAQ

Identity authentication verifies that the person accessing and signing a document is who they claim to be. Methods include MFA, 2FA, access codes, and KBA—each adding a layer of confidence before the signer can proceed.
Two-factor authentication (2FA) requires exactly two forms of verification, while multi-factor authentication (MFA) requires two or more. Both add security beyond a simple email link by confirming identity through additional channels.
KBA validates signers by asking questions only they should be able to answer—such as previous addresses or financial history—before granting document access.
Yes. Foxit eSign lets you configure authentication on a per-recipient basis, so you can apply stronger verification to high-risk signers while keeping it simple for others.
QES is a higher-assurance electronic signature that meets strict identity verification requirements under regulations like eIDAS. Foxit eSign supports QES through ZealiD integration for workflows that require it.
Authentication adds a brief verification step, but it's designed to be straightforward. Most signers complete verification in seconds, and the added confidence protects both parties.
Authentication creates verifiable evidence that the correct person accessed and signed the document. This strengthens audit trails and supports regulatory requirements in industries like healthcare, finance, and government.
