1. A method, comprising:

  • training, by a processor, for one or more secondary signatures of a user;

    identifying, by the processor, one or more inherent expressions of the user as the one or more secondary signatures;

    authenticating, by the processor, the user using a primary signature and at least one of the one or more secondary signatures; and

    unlocking, by the processor, a lock to permit the user access to a locked item responsive to an authentication of the user using the primary signature and one or more of the secondary signatures,wherein the one or more inherent expressions are unintended expressions performed by the user (i) in relation to the user providing the primary signature (ii) while being unrelated directly to the physical, intentional interaction of the user providing the primary signature, and wherein each of the primary signature and the at least one of the one or more secondary signatures are used as separate identification factors in a multi-factor authentication of the user;

    wherein the one or more inherent expressions comprise one or more sounds produced by the use.
