A computerized and networked system protects individuals against identity theft without the need to disclose the detailed personal information of the individuals. Furthermore, the system helps prevent loss and damage to consumers, financial institutions and merchants caused by financial crimes related to identity theft. In addition, users can conduct payments in a secure manner without the need to use any traditional financial instrument. A pass code can be generated for each transaction and sent to a user's personal communications device. When the correct pass code is received from the user, the transaction is then authorized.
