  • For 3DS 1.0.2, the ECI 06 value may be utilized as an authentication response from the Issuer ACS, at the issuer’s discretion. For example, issuers that use risk-based authentication may provide an ECI = 06 for a transaction that does not require step-up, also known as frictionless authentication. These issuers may reserve an ECI = 05 for transactions that were successfully stepped-up.
  • For 3DS 2.0, the ECI 06 value can only be used to indicate that a “Merchant attempted to authenticate the cardholder”.
