Uses crypto.getRandomValues() for cryptographically secure randomness. Never sent to servers.

Use 12+ characters, mix cases/numbers/symbols. Passphrases like CorrectHorseBatteryStaple are strong & memorable.

Don't use birthdays, names, or common words. Enable "No Repeating" & "Exclude Ambiguous" for maximum security.

Higher entropy = harder to crack. 60+ bits is good, 80+ is strong, 100+ is very strong against brute force.
