Why do e-signatures need multi-factor authentication?
Because signing a document is easy — proving who actually signed it is what builds trust. Multi-factor authentication adds a critical layer of security before anyone puts pen to screen.
With Zoho Sign, you can verify a signer's identity through an email or SMS OTP, government ID, knowledge-based authentication, and more, so only the intended recipient can access and sign your document. It's a simple step that turns a signature into real, verifiable proof.
After all, a signature is only as strong as the identity behind it.
