Methods and apparatus for multi-factor authentication risk detection using beacon images

Methods and apparatus are provided for multi-factor authentication of a user using beacon images. Access is provided to a protected resource by receiving a browser request for a beacon image, wherein the beacon image is embedded in an access request page (e.g., a login page) for the protected resource; collecting data in response to the browser request from a device associated with the browser; and providing the data for a risk assessment of the request. The beacon image comprises, for example, a substantially invisible image and can be loaded when the access request page is loaded in the browser or when a user submits credentials in the access request page.
