A method for provisioning a user account, the method comprising: sending, by a token requestor computer, a first token request message to a first transaction processing network, wherein the first token request message includes an account identifier that identifies a user account associated with the first transaction processing network and a second transaction processing network, such that transactions initiated using the account identifier are processed by one of the first transaction processing network or the second transaction processing network; receiving, by the token requestor computer, a message from the first transaction processing network indicating that the account identifier is associated with the second transaction processing network; receiving, by the token requestor computer, a first token and a result of an authentication process performed by the first transaction processing network from the first transaction processing network; sending, by the token requestor computer, a second token request message to the second transaction processing network, the second token request message including the account identifier and the result of the authentication process; and receiving, by the token requestor computer, a second token from the second transaction processing network, wherein the second token is generated by the second transaction processing network based on the result of the authentication process performed by the first transaction processing network, and wherein the first token and the second token are provisioned on a user device of a user of a user account identified by the account identifier. sending, by a token requestor computer, a first token request message to a first transaction processing network, wherein the first token request message includes an account identifier that identifies a user account associated with the first transaction processing network and a second transaction processing network, such that transactions initiated using the account identifier are processed by one of the first transaction processing network or the second transaction processing network; receiving, by the token requestor computer, a message from the first transaction processing network indicating that the account identifier is associated with the second transaction processing network; receiving, by the token requestor computer, a first token and a result of an authentication process performed by the first transaction processing network from the first transaction processing network; sending, by the token requestor computer, a second token request message to the second transaction processing network, the second token request message including the account identifier and the result of the authentication process; and receiving, by the token requestor computer, a second token from the second transaction processing network, wherein the second token is generated by the second transaction processing network based on the result of the authentication process performed by the first transaction processing network, and wherein the first token and the second token are provisioned on a user device of a user of a user account identified by the account identifier.
