Generate cryptographically secure passwords and passphrases while testing password strength, crack time, and Shannon entropy locally in your browser.

Password Security Hub is an all-in-one cryptographic security utility that combines a high-entropy password generator with a real-time password strength, crack-time, and Shannon entropy analyzer.
Utilizes window.crypto.getRandomValues() to sample cryptographically secure pseudorandom numbers from OS hardware entropy pools. Evaluates password strength using multi-factor criteria: character length, character diversity, dictionary pattern matching, and brute-force crack time estimates.

Never. Every password is generated and analyzed strictly on your local device using the browser native Web Crypto API. No passwords ever touch a network socket.
Cryptographically secure passwords utilize true OS-level entropy pools rather than predictable pseudo-random seeds (like Math.random), ensuring complete unpredictability.
Password entropy measures the unpredictable randomness of a password in bits. Higher entropy directly increases the exponential compute time required to brute-force a password.
