Claim Text:
1. A method for generating and authenticating a one time dynamic password based on context information comprising: receiving, by an authentication server, from a user device and without providing any variable to the user device a first one time dynamic password and at least one of an application identifier or a device identifier for the user device, wherein the first one time dynamic password is generated based on a first dynamic value and a user personal identification number (PIN) of a user of the user device and the first dynamic value is generated based on context information related to the user; generating, by the authentication server, a second one time dynamic password based on a second dynamic value received from a separate context management server and the user PIN, wherein the second dynamic value is generated based on the context information used to generate the first dynamic value and the context information used to generate the first and second dynamic values is only accessible by the user device and the context management server; and authenticating, by the authentication server, the first one time dynamic password when the first one time dynamic password matches with the second one time dynamic password.
