Password Entropy & Security Standards

Password entropy measures the randomness and unpredictability of a secret string, expressed in bits of entropy (E = log2(R^L) where R is the pool size and L is length).

Entropy Requirements

  • Under 40 bits: Vulnerable to instant offline brute-force cracking.
  • 60 - 80 bits: Standard security suitable for basic web authentication.
  • 128+ bits: High-security threshold resistant to GPU cluster dictionary attacks.
