A system and method for performing multifactor mobile authentication are described whereby a mobile communications device includes a contactless reader for receiving and validating a unique identifier stored in an external authenticating module prior to granting access to locally stored electronic authenticating material required to access an external resource. In one embodiment, the mobile communications device is a mobile telephone having an RFID reader for receiving the unique identifier from an RFID tag incorporated into the external authenticating module. Preferably, the external authenticating module is associated with a user, such as by being part of the user's jewelry or clothing. The mobile authentication device includes an RFID authenticator module that detects external resource access requests and checks whether the requested resource is on a list of resources that require additional user authentication prior to granting access to locally stored authenticating material.
