Zero-Knowledge Proofs and Passwords

Zero-knowledge is one of the most misused terms in security marketing. Here is the cryptographic definition and how to tell if a product actually implements it.

This guide covers the key concepts, practical steps, and common mistakes to avoid when addressing this aspect of password security.

Best practices

  • Use a dedicated password manager for all credentials
  • Enable multi-factor authentication wherever supported
  • Use unique passwords for every account
  • Regularly audit accounts for breached credentials
  • Generate passwords with a cryptographically random generator like PassGeni

How PassGeni helps

PassGeni addresses this challenge directly through its AI-seeded generation engine. Passwords are created client-side using JavaScript's crypto.getRandomValues() API โ€” no data ever leaves your browser.

The Password DNA Score provides a 7-point quality audit so you know exactly how strong each generated password is before you use it.
