1. A device for determining a threat level, comprising:

  • a biometric sensor; and

    a processing system configured to;

    receive, from the biometric sensor, data corresponding an attempt to verify an identity of a user;

    determine, based on the data corresponding to the attempt, one or more authentication parameters associated with the attempt;

    authenticate the user based on determining that a score associated with the attempt satisfies an authentication condition associated with a biometric template, wherein the authentication condition comprises a threshold value, and authenticating the user is based on determining that the score associated with the attempt satisfies the threshold value;

    after authenticating the user, determine one or more device usage parameters within a time window of authenticating the user;

    determine a threat level based on the one or more authentication parameters and the one or more device usage parameters;

    cause an action to be performed by the device based on the threat level, wherein the action comprises raising or lowering the threshold value associated with the authentication condition to an updated threshold value based on the threat level;

    receive, from the biometric sensor, data corresponding a subsequent attempt to verify the identity of the user; and

    authenticate the user based on determining that a score associated with the subsequent attempt satisfies the updated threshold value.
