About this tool

Strong crypto without turning the page into a boring form.

This generator uses the Web Crypto API (crypto.getRandomValues) with uniform rejection sampling to avoid bias over the character set. All generation happens in the browser. You can pick the length, character sets and exclude visually ambiguous characters such as 0/O, 1/l and I.

How to use

The right flow in three clicks.

  1. Choose length. For general use, 16 characters is a solid minimum.
  2. Enable at least one set. More variety means more entropy.
  3. Click "Generate new" and copy the password with the copy button.

We only show partners that make editorial sense for security. On PT-BR pages, an English resource may appear as a fallback when no equivalent local option exists yet.
