A method of remotely accessing a postage security account at a daa center (30) from a remote user device begins with a remote user assigning a password to the user's postage security account at a data center (30). A cryptographic key corresponding to the user's postage security account is provided to the remote user device and is stored at the data center (30). The password and the cryptographic key are combined at the remote user device and the data center (30) respectively to obtain a user authentication key. An authentication algorithm is performed using the user authentication key to obtain a remote access message. The remote access message is sent to the data center (30) to initiate request for access to the postage security account by the remote user device. The remote user device is authenticated for accessing the postage security account when the data center (30) verifies the remote access message.
