What Makes a Password Strong?
According to modern cybersecurity standards (such as NIST SP 800-63B), length and unpredictability trump forced complexity. A 16-character random string or a 4-word Diceware passphrase has vastly higher entropy than an 8-character password with symbol substitutions like P@ssw0rd!.
🔐 Cryptographic Randomness
Generated using crypto.getRandomValues(), preventing the mathematical pattern prediction weaknesses inherent in Math.random().
🧠 Memorable Passphrases
Multi-word passphrases deliver high entropy while remaining easy to remember and type on mobile touchscreens without copy-pasting.
🔒 100% In-Browser Privacy
Passwords are generated strictly in your device's ephemeral memory. No password or parameter is ever logged or transmitted across the web.
