Password Checker

Password Checker is an open-source Windows application that checks whether a password has appeared in previous data breaches. It is intended for people who want to determine if a password may have been exposed through a known breach.

Its main function is focused on breach exposure checks. The software does not need additional described functions to provide this specific purpose.

MirrorNest distributes the official Windows build directly from its own storage. Each mirrored build is scanned for malware before it is published, placing Password Checker within the Windows software category while preserving its open-source licensing.
