About Password Generator
How strong is "strong"?
Each bit of entropy doubles brute-force time. 60 bits ≈ days to crack offline; 80 bits ≈ years; 100+ bits is effectively unbreakable today. Use a password manager — you don\u2019t need to memorize 80-bit passwords.
Why randomness matters
This generator uses `crypto.getRandomValues` — cryptographically secure. Math.random() is predictable enough that attackers can sometimes reverse-engineer it. Always use crypto-grade randomness for passwords.
Diceware / passphrase alternative
A 6-word random passphrase from a 7,776-word list has ~77 bits of entropy and is much easier to remember. Use whichever you can actually use without writing down.
