Strong randomness. Zero exposure.
Generate a unique password with the length and character types you need. This tool uses your browser’s cryptographically secure random generator; the result is created locally and never sent to Aruscus.
Cryptographically random
Uses the browser Web Crypto API with unbiased character selection—not Math.random.
Useful controls
Choose password length and include uppercase, lowercase, numbers, or symbols.
Ambiguity reduced
The default character sets omit lookalikes such as zero, O, one, l, and I.
Never stored
Generated passwords stay in this tab and disappear when the page closes or refreshes.

Common questions.
Is this password generator secure?
It uses crypto.getRandomValues, the browser’s cryptographically secure random source, and avoids modulo bias when selecting characters.
Does Aruscus see or save generated passwords?
No. Generation happens locally, and passwords are not uploaded, logged, or written to browser storage.
How long should a password be?
Longer is generally stronger. Twenty characters is a practical default for randomly generated passwords when a site permits it.
Should I reuse a generated password?
No. Use a unique password for every account and save it in a trusted password manager.
