About this tool

Strong passwords combine length with mixed character types. This generator creates random passwords locally using secure browser randomness—nothing is transmitted or logged.

Tune length and character sets to satisfy site rules, then copy into a password manager rather than reusing credentials.

Common use cases

  • Creating unique passwords for new accounts
  • Rotating credentials after a breach
  • Generating API keys or temporary access tokens
  • Meeting complexity rules for enterprise systems

How to use

  1. Set password length and included character types.
  2. Exclude ambiguous characters if you need easier transcription.
  3. Generate a new random password.
  4. Copy it directly into your password manager—do not reuse across sites.

Understanding the result

  • Longer passwords exponentially increase brute-force difficulty.
  • Including symbols and mixed case satisfies most complexity policies.
  • Each click produces independent random output—previous passwords are not stored.
  • Generated strings are only as secure as where you store them; use a reputable password manager.

FAQ

How long should a password be?

At least 12–16 characters for general use. Longer is better when the site allows it.

Are generated passwords stored?

No. They exist only in your browser session until you copy or refresh.

What characters can I include?

Typically uppercase, lowercase, digits, and symbols. Disable sets that a site forbids.

Is this cryptographically secure?

The tool uses the browser's crypto-grade random source for generation.
