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”.
