What authentication method is needed if a credible witness is not personally known to the notary?

The correct answer involves using a multi-factor authentication procedure when a credible witness is not personally known to the notary. In this context, multi-factor authentication enhances security and verifies the identity of the individual without prior personal acquaintance. It typically requires two or more verification methods, which may include knowledge-based verification (like answering personal security questions), ownership verification (such as providing a government-issued ID), or even biometric verification (like fingerprints).

This approach is crucial in ensuring the integrity of the notarization process, as it mitigates risks associated with identity fraud or misrepresentation, especially when the notary does not have firsthand knowledge of the witness. By utilizing multi-factor authentication, the notary can confidently establish the credibility of the witness before proceeding with the notarization.

In contrast, visual identification focuses on what the notary can see and does not provide the same depth of confirmation if the person is unknown. Telephone verification may not be as reliable for confirming the identity of a witness and can be susceptible to impersonation. Written confirmation can also provide some assurance but may lack the immediacy and robustness that multi-factor authentication supply.
