In an era dominated by data breaches and credential stuffing attacks, the average internet user faces significant challenges in maintaining secure authentication practices. This paper examines the utility of "CheckMyPassword.com.au," an Australian-facing portal integrated into the global "Have I Been Pwned" (HIBP) ecosystem. By analyzing the technical architecture of k-anonymity and SHA-1 hashing, this paper explores how the service allows users to verify the integrity of their passwords without exposing sensitive credentials to third-party risks. Furthermore, it discusses the psychological and behavioral impacts of real-time breach notifications on user security hygiene. checkmypasswordcomau
