Abstract
The invention provides a method and system for simultaneously authenticating a user using two or more factors, such as both a password and a physical token or both a password and biometric information. The user presents a physical token including a storage device to a processor and attempts to log in using a first password; the processor includes a login service which receives the first password, accesses the storage device to transform the first password into a second password, and authenticates the second password using an operating system for the processor. The storage device includes encrypted information regarding the second password which can be relatively easily determined in response to the first password, but which cannot be relatively easily determined without the first password. The system or the storage device may also store information for biometric authentication of the user.
