Likelihood of fraud is reduced by having at least one of an identifier of a location from where a request is submitted or information that can lead to identification of the location, submitted with or in addition to a request. Then, determination is made to whether to service the request, based at least in part on the location from where the request is submitted. In various embodiments, the location may be compared against predetermined permissible location(s) or a current user location. The request may be a request to charge an amount against an account, such as a credit card account, a request to access a physical resource, such as a VPN, or an informational resource, such as account information, or a request to access a secured area.
