Abstract
A method and apparatus for knowledge-based authentication by a cloud-based authentication service are described. A cloud-based authentication service is to track credential usage of an end-user at the cloud-based authentication service. The authentication service receives a credential request for credentials associated with the end-user from a relying party website. The end-user no longer has authentication credentials for access to the relying party website. The authentication service issues a dynamic knowledge-based (KB) challenge to the end-user, the dynamic KB challenge being based on at least some of the tracked credential usage of the end-user. The processing logic receives a response to the dynamic KB challenge from the end-user and sends temporary credentials to the relying party for the end-user when the response is validated.
