Abstract: Systems and methods for improving security in mobile payment systems are described. A user device may be operated to request temporary account data for an account. No actual account number may be stored on the device. A remote system may correlate temporary account data to actual account data and transmit temporary account data to the user device, which use the data to make a purchase or generate a temporary account number than may be used to make a purchase. Temporary account data may be automatically erased or expire. A purchase authorization request may be sent by a merchant with temporary account data to a provider of temporary account data. The provider may transmit a request for purchase authorization using actual account data to a payment processor, sending a response to the merchant that does not include actual account data based on a response from the payment processor.
