常見問題
At least 12 characters for standard accounts, 16+ for sensitive accounts like banking or email. Each additional character exponentially increases the time needed to crack it. Our generator supports up to 256 characters.
Length combined with randomness. A human-chosen 20-character password is weaker than a randomly generated 12-character one because humans follow predictable patterns. Our tool uses your browser's cryptographic random number generator (CSPRNG) for true unpredictability.
Passphrases like 'correct-horse-battery-staple' are easier to remember but need 4+ random words to match a 12-character random password's strength. Use passphrases for accounts you type manually, random passwords for accounts with a password manager.
Yes — our generator runs entirely in your browser using JavaScript. No passwords are sent to any server, stored in any database, or logged anywhere. You can verify this by disconnecting from the internet and using the tool offline.
Only when a breach is suspected. NIST guidelines no longer recommend routine password rotation — it leads to weaker passwords. Instead, use unique random passwords per account and enable two-factor authentication.
Yes, our bulk generation feature creates hundreds of passwords simultaneously with consistent security settings. This is useful for provisioning team accounts, testing environments, or generating API keys.
