Abstract: Embodiments of the invention relate to apparatuses and methods for identity verification. For example, in one embodiment, a financial institution has a system to generate authentication questions to be used when authenticating a customer when the customer is trying to access and/or use the customer's account. The authentication system is configured to ask one or more authentication questions each time the customer tries to access or use the account, where the authentication questions are generally out-of-wallet questions that constantly change from one authentication attempt to the next. For example, in one embodiment, the questions include behavioral, historical, and transaction based questions generated from information available about a customer's financial account.
