About PassCheck
Building accessible, zero-knowledge cybersecurity tools that respect human privacy above all else.
Zero-Knowledge First
PassCheck ensures security utilities never require users to trust remote servers with their plain credentials.
Mathematical Precision
Our engine replaces arbitrary rules with rigorous information entropy calculations and empirical hardware attack benchmarks.
Breach Transparency
Empowering users with real-time exposure radar backed by the official Have I Been Pwned corpus.
