Password Generator

Choose the length and the characters to use. The password is generated on this page, on your device; it is never sent or stored.

This tool needs JavaScript

The tool runs in your browser, so nothing can be calculated with JavaScript turned off. The rest of the page is still readable.

Length 16

Characters Upper case (A-Z) Lower case (a-z) Digits (0-9) Symbols (!@#$%…)

Leave out look-alikes (l, 1, I, O, 0)

How strength is measured

Randomness comes from the browser's cryptographic generator (crypto.getRandomValues); Math.random is not used and characters are picked without modulo bias. Strength is entropy in bits: length × log₂(pool size). Under 60 bits counts as weak, 60 to 80 fair, 80 to 100 strong, 100 and above very strong. Length buys more than symbols do: a plain 16-character password beats a complex 12-character one. Keep it in a password manager.
