Abstract: A system and method for integrating the Internet front end -sign on processes of the various systems of a financial institution which allows a customer to view and access its various financial accounts with the institution. During the initial sign up for the online access. to its accounts, a customer creates his/her User ID and password online during the same session. Once the customer has signed on (password) and verified ownership of at least one account, the system displays all of the customer's accounts that are available for access via the Internet website. The online ownership verification uses only a single account of the customer and the ownership verification criteria associated with the account. The account used for verifying a customer is first determined based on the accounts selected by the customer for accessing online. From the selected accounts, the system of the present invention creates a verification hierarchy with respect to the accounts.
