Systems and methods for authentication are disclosed. A method for biometric authentication, includes: receiving a first attempt to validate an identity using biometric information; determining if the first attempt satisfies a first authentication criterion for authentication, wherein the first authentication criterion corresponds to the first attempt; if the first attempt does not satisfy the first authentication criterion, subsequent to determining that the first attempt does not satisfy the first authentication criterion, receiving a subsequent attempt to validate the identity using biometric information, wherein a second authentication criterion corresponds to the subsequent attempt, and wherein the second authentication criterion has a lower false acceptance rate than the first authentication criterion; determining if the subsequent attempt satisfies the second authentication criterion; and if the subsequent attempt does satisfy the second authentication criterion, validating the identity in response to determining that the subsequent attempt does satisfy the second authentication criterion. |

1. A device, comprising:
a biometric sensor; and a processing system configured to:
receive, from the biometric sensor, data corresponding a first attempt to validate an identity of a user;determine that a score associated with the data corresponding to the first attempt does not satisfy a first authentication threshold for authentication, wherein the first authentication threshold corresponds to the first attempt;subsequent to determining that the first attempt does not satisfy the first authentication threshold, receive, from the biometric sensor, data corresponding to a subsequent attempt to validate the identity of the user, wherein a second authentication threshold corresponds to the subsequent attempt, and wherein the second authentication threshold is higher than the first authentication threshold;determine whether a score associated with the subsequent attempt satisfies the second authentication threshold; andif the score associated with the subsequent attempt does satisfy the second authentication threshold, validate the identity of the user in response to determining that the score associated with the subsequent attempt does satisfy the second authentication threshold. |
