What Is Credential Stuffing and Why Your "Unique" Password Matters

Credential stuffing automates login attempts using breached username/password pairs. Here is how it works and why unique passwords per site are non-negotiable.

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
