Janrain explains how this new verification service works, "This phone-based authentication service can use any phone (mobile or landline) as a second authentication factor. The user enters a myOpenID username and password as usual, then simply answers an automated instant telephone call and presses #. This completes the authentication process. Complete two-factor authentication and identity protection is instantly enabled with no need for tokens, smart cards or certificates. CallVerifID is currently available for free to myOpenID users and as an additional service for business clients provisioning OpenIDs to both customers and employees."
