Abstract
A system and method allows a user to register one or more PINs on one or more user devices, and then authenticates the user to a server via the PIN and a token deposited on the user device being used by the user to allow access to an application on the user device. Individual tokens, or all tokens deposited on the user devices for a user account, may be invalidated, and the user is prevented from authenticating himself or herself via a PIN to allow access to an application on any device for which the last token deposited was invalidated, until the same or different PIN is registered for that device.
