In an exemplary embodiment, a system includes a memory operable to store a user account identifier associated with a user account and a mobile device identifier associated with a mobile device. The memory is also operable to store a first user credential and a second user credential, the second user credential, wherein the second user credential comprises user input data captured by a sensor. The system includes a network interface operable to receive a request to authenticate a requesting user. The system also includes a processor operable to determine information included in the request to facilitate authentication of the requesting user and whether the information included in the request matches the information associated with the user account. The processor is further operable to authenticate the requesting user if the request is associated with the user account and information included in the request matches the information associated with the user account.
