Abstract

A method and system for providing a service node for authenticating online transactions. The authentication service node improves the ability to verify that an online transaction is made by an authenticated user. The authentication service node receives a request to authenticate a transaction, such as a purchase from an online merchant made by a purchaser using a first device and providing a user identifier such as a user name and password. The authentication service node identifies a second device associated with the provided user identifier, where the second device has been configured to validate inputs by a person associated with the provided user identifier. The service node sends the second device a request to confirm the online transaction and receives a determination specifying whether inputs providing by the user of second device match inputs provided previously by the user associated with the user identifier.
