Frequently asked questions
Is it safe to generate a password online?
This tool uses the browser's built-in cryptographically secure random generator. Everything happens locally with no network, logging or upload — the result appears only on your screen.
What makes a strong password?
Aim for at least 12 characters mixing upper/lowercase, numbers and symbols. The tool shows an entropy-based strength estimate.
What if I forget a generated password?
We store nothing. Save it in a password manager or another safe place; it cannot be recovered from this tool.
