What this tool does

Generate strong random passwords or memorable passphrases entirely in the browser.

Method

Random selections use the browser's cryptographic random-number generator with rejection sampling to avoid modulo bias; unsupported browsers fail safely instead of using Math.random.

Example

Generate five 20-character passwords with mixed case, numbers, and symbols while excluding ambiguous characters.

Common questions

Is it free?

Yes. The core tool and its standard result or export are free to use.

Do I need an account?

No for the core utility. An account or private management token is requested only for capabilities that must persist, such as editable dynamic QR links.

Can I trust the result?

The method and assumptions are visible above. Time-sensitive tools name their sources and freshness; important financial, safety, legal, or operational decisions should be verified with the primary authority.
