About this tool
Each batch contains five independently generated passwords with lengths of 16, 17, 18, 19 and 20 characters. Generate batch creates a fresh set using crypto.getRandomValues and rejection sampling, avoiding modulo bias when selecting characters.
The alphabet is fixed and excludes some ambiguous letters and digits. The editable field is separate from the batch and only estimates entropy from length and character classes; it is not a password-strength guarantee. There are no length or alphabet controls. Outputs are generated locally; clipboard, extensions and device security still matter.
Frequently asked questions
Can I choose the length and character sets?
Not in this version. Each batch uses a fixed alphabet and lengths of 16–20 characters. The editable estimate field does not change generated passwords.
