Portable security tool for user authentication

Abstract:

An apparatus includes a memory, and a processor. During a first mode of operation, the hardware processor obtains a first key and a second key from a first system. The first system includes a first subsystem and a second subsystem. The first key indicates that a user previously accessed the first subsystem and the second key indicates that the user previously accessed the second subsystem. During a second mode of operation, the processor receives a request indicating that the user is seeking to access the second system. The processor then performs an authentication of the user, which includes receiving an authentication string from the user that includes a first user key and a second user key, determining that the first user key matches the first key, and determining that the second user key matches the second key. In response, the processor provides the user with access to the second system.
