Update the Signer's authentication mode for ongoing Signature Requests (SES only)

You can now change a Signer’s authentication mode after activation, as long as the Signature Request’s signature_level is Simple eSignature (electronic_signature), and the Signer is in status initiated or notified. This capability does not apply to Advanced or Qualified eSignatures (AES/QES).

If you modify the OTP mode while the Signer is on the authentication step, any code already sent is invalidated, and the new method applies.

For more information on the authentication, you can consult our dedicated guide.
