Key features

  • Selects characters with crypto.getRandomValues and rejection sampling in the browser.
  • Configures a length from 4 to 64 and includes uppercase, lowercase, numbers, or symbols.
  • Can remove look-alike characters such as 0, O, 1, l, and I.
  • Generates 1, 3, 5, 10, or 20 passwords for individual or bulk copying.
  • Shows a theoretical entropy estimate derived from the selected pool size and length.

How to use

  1. Set the password length and character groups.
  2. Choose whether to exclude ambiguous characters and how many passwords to create.
  3. Copy a result or regenerate the list.

Examples

  • Create a new account password

    Choose length and character groups, optionally excluding ambiguous characters.

  • Prepare test accounts in bulk

    Generate up to 20 password candidates independently and copy the complete list. Duplicates are not removed.

Privacy

Passwords are generated in your browser; QuickKit does not store the results or send them to a server.

Requirements

The entropy display assumes uniform use of the selected character pool and does not guarantee the security of an account or password.
