Abstract
A system and computer-based method for using a one-time password (OTP) to authenticate an identity of a cardholder in a financial transaction initiated by the cardholder with a merchant via a first communication medium. A one-time password is generated at an interchange computer system and transmitted to the cardholder via a second communication medium. The cardholder is prompted to enter access credential information, including the one-time password. When the entered access credential information is verified (e.g., the entered one time password is equal to the generated one-time password), a successful authentication is indicated to the merchant.
