Abstract: Examples described herein include systems, methods, instructions, and other implementations for data security with integrated installment payment systems. In one example, account security system receives a checkout communication that includes data describing a validated checkout system of a merchant system. A client token is transmitted in response to an authentication that the checkout communication is from the validated checkout system, and an account communication including the client token and secure client information is received from a client device. An installment payment communication associated with the secure transaction is received from a system other than a merchant system involved in the transaction. The secure transaction is then facilitated following receipt of the installment payment communication.

Abstract: Examples described herein include systems, methods, instructions, and other implementations for data security. One example includes receiving a checkout communication received from a merchant system, where the checkout communication does not include client information, and processing the communication to authenticate a validated checkout system. A client token is generated in response to an authentication that the checkout communication is from the validated checkout system and transmitted to allow verification of the merchant system. An account communication is then received including the client token and client information, where the client information is not received from the merchant system. A tokenized client account number is generated and used to allow the merchant system to process the secure transaction without access to the client information.
