Abstract: A method is disclosed. The method includes receiving, by a token service computer, a detokenization request message comprising a first token from a network processing computer, and then determining a first credential that is stored in association with the first token in a database. The method includes determining a user identifier that is stored in association with the first credential in the database, determining that a second credential is stored in association with the user identifier, generating a detokenization response message comprising the second credential, and providing the detokenization response message to the network processing computer.

Abstract: A method includes a server computer receiving a cryptogram request message comprising a token associated with a first credential during an interaction between a user of a user device and a resource provider of a resource provider application on the user device. The server computer generates a detokenization request message comprising the token. The server computer then provides the detokenization request message to a token service computer. The server computer receives a detokenization response message comprising a second credential from the token service computer. The server computer obtains a cryptogram for the interaction. The server computer generates a cryptogram response message comprising the second credential and the cryptogram, and then provides it in response to the cryptogram request message.
