Abstract: Systems, methods, and apparatuses for authenticating a user based at least in part on a location of the user or a location of a user device are described. The user may be authenticated as part of a financial transaction or as part of a login process for a computing device. The user device was previously bound or associated with the user. During the authentication, a system (e.g., a financial institution computing system or a backend authentication system) requests location information from the user device. The location information may be packaged as a digital fingerprint of the user device, which can only be created from the user device. Based on the location information, the user can be authenticated thereby approving the transaction or login request.
