Systems and methods for implementing a location token service (LTS) to enhance the security of mobile device identity tokens by using the location of the mobile device to augment the tokens. The LTS enforces re-authentication (login) of the mobile device to one or more applications if the mobile device moves beyond a threshold distance from the location of the last use of the token within a time period defined in a temporal threshold. The LTS increases authentication strength and drastically reduces the potential for spoofing or otherwise permitting unauthorized access to one or more applications on the mobile device.
