The idea

A security check with a clear answer.

Reusing a compromised password can put several accounts at risk, but finding out whether one has appeared in a breach should be quick. Breach Guard provides a small desktop interface for running that check without navigating through a larger security tool.

The Python application hashes the password and checks it against the Have I Been Pwned password dataset. It then reports whether a match was found and, when needed, prompts the user to replace the exposed password.

From the checker

One input. A direct result.
