An approach is provided for securely storing and managing sensitive data. A system and method are provided that include a central device that receives an actual data value from a requestor, encrypts the actual data value, obtains a replacement value for the encrypted actual data value, obtains a secondary replacement value based on the encrypted actual data value, and transmits the replacement value to the requestor for storage by the requestor. The system and method also includes a storage device for storing the secondary replacement value in association with the encrypted actual data value at a secure location. The requestor can later use the replacement value to retrieve the actual data value from the central device.
