Signer Authentication

Signer authentication is the process of verifying that the person accessing a signing workflow is actually the intended recipient before allowing them to sign a document.

What it means

Authentication methods range from simple (email link delivery — the signer must have access to the inbox) to strong (SMS PIN, access code, knowledge-based authentication, or biometrics). Higher-value documents warrant stronger authentication. The authentication method used and evidence collected should be recorded in the audit trail.

Why it matters for e-signatures

Choosing the right authentication level is a risk decision. SignOwl supports multiple authentication factors so you can match the authentication strength to the sensitivity of each document.

Frequently asked questions

What is the most common signer authentication method?

Email link delivery is the most common method. The assumption is that control of the email inbox constitutes sufficient verification for most business documents.

When should I require stronger authentication?

Use SMS PIN or access codes for financial and HR documents. Consider KBA or ID verification for high-value contracts, regulated industries, or when signer identity is critical.
