How to use the Password Generator

  1. Drag the length slider anywhere from 8 to 128 characters.
  2. Toggle which character sets to include: lowercase, uppercase, digits, and symbols.
  3. Optionally exclude visually ambiguous characters like l, 1, I, O and 0.
  4. Set how many passwords to generate at once (1 to 20) and click "Generate".
  5. Copy any individual password, or use "Copy all" to grab the whole batch.

Why use ZillaKit's Password Generator?

Reused or predictable passwords are one of the most common causes of account compromise. This generator uses the browser's cryptographically secure crypto.getRandomValues API — not a plain Math.random() — to pick every character, so the output has genuine, high-quality randomness suitable for real account security. You control exactly which character sets are used and the exact length, and a live strength meter estimates the entropy of your configuration so you can see the effect of each toggle in real time. Generate one password or a batch of up to 20 at once for setting up multiple accounts in one sitting. Everything happens locally in your browser tab — no password you generate is ever transmitted, logged, or stored on a server, and the tool is completely free to use.

FAQ

Is this safe to use for real account passwords?

Yes. It uses crypto.getRandomValues, the same cryptographically secure random number source used by security-sensitive browser APIs, and everything runs locally — nothing is ever sent to a server.

How long should my password be?

Most security guidance recommends at least 12-16 characters with a mix of character types; use 20+ for highly sensitive accounts where the site allows it.

What does the strength meter measure?

It estimates entropy (randomness) based on password length and the size of the character set in use, then maps that to a Weak/Fair/Strong/Very Strong label.

Why exclude ambiguous characters?

Characters like lowercase L, uppercase I, and the digits 0/1 can look identical in some fonts, which matters if you need to type the password by hand from a printout.

Are the passwords stored anywhere?

No. Passwords are generated and displayed only in your browser session and are not saved, logged, or transmitted anywhere.
