Is this password generator truly random and secure?

Yes. Zolkit uses the Web Crypto API's crypto.getRandomValues function, which provides cryptographically strong random numbers suitable for security-sensitive applications — far stronger than Math.random().

Are my generated passwords stored or logged?

Never. Password generation is entirely client-side. The password is never transmitted over the network and is not stored in any database, log file, or browser storage on our end.

What is a good password length?

Security professionals generally recommend at least 16 characters for high-value accounts. For most purposes, 12–16 characters with mixed character types provides excellent protection against brute-force attacks.

What does 'Exclude ambiguous characters' do?

It removes characters that look similar in some fonts: 0 (zero), O (uppercase O), l (lowercase L), 1 (one), and I (uppercase i). This prevents confusion when reading passwords aloud or typing them manually.

How is password strength calculated?

Strength is scored by combining password length and the number of distinct character sets used (uppercase, lowercase, digits, symbols). Longer passwords with more character variety score higher.

Can I use this to generate PINs or passphrases?

For numeric PINs, enable only Numbers and set your desired length. For passphrases, this tool generates random character strings rather than word-based phrases — use a dedicated passphrase generator for word-based passwords.
