WebApr 4, 2024 · False Rejection Rate, or FRR, is a measure of how often a biometric authentication system incorrectly rejects an authorized user. Authentication systems should strive to have the lowest possible FRR in order to avoid interruptions in productivity and reduce user frustration and users' tendencies to seek workarounds to authentication flows. WebDec 12, 2014 · False acceptance refers to an unauthorized user given access to a system which he is not allowed to access.
