Disclosed is a system and associated method for restricting access to a customer's online banking account. The system typically includes a processor, a memory, and an online banking module stored in the memory. The module is typically configured for determining that a computing device has initiated a first online banking transaction associated with the customer's online banking account. If the first online banking transaction is within a first restricted transaction definition and if the computing device is not enrolled with the customer's online banking account, geographic location information associated with the computing device and geographic location information associated with a first mobile device enrolled with the customer's account are received. The module determines whether the location of the computing device is proximate to a predefined location and/or whether the location of the computing device is proximate to the location of the first mobile device.
