Methods for authenticating a person to participant in a videoconference based on facial imaging, fingerprint imaging, other biometric information, passwords, and physical mediums are described. Identity information for the potential participant may be received, and a recognition algorithm may be performed to determine whether the received identity information for the potential participant matches pre-stored identity information for a first person, e.g., where the potential videoconferencing participant claims to be a specific person. If the recognition algorithm determines a match, the potential videoconferencing participant may be authenticated to participate in the videoconference.
