What this tool does
A focused job, with a visible boundary.
Create a new credential with secure device randomness without submitting it to a password-generation service.
Password and passphrase modes
Visible entropy estimate and one-tap copy
Know the limits
Local does not mean unlimited.
Browser processing protects the file from an upload workflow, but the browser, device, output format, and selected settings still matter.
- A generated credential is only safe if it is stored and used securely.
- Browser extensions, compromised devices, screen recording, or clipboard history remain outside this page’s control.
- Do not reuse the same generated credential across services.

Clear answers
Credential generator questions.
Is the generated password sent anywhere?
No. Generation uses crypto.getRandomValues in this browser and the page does not submit the result.
Should I memorize a random password?
Usually not. Store unique random passwords in a reputable password manager. A multi-word passphrase can be more suitable when memorization is genuinely required.
Is copying to the clipboard completely safe?
No. Other software, clipboard history, extensions, or a compromised device may expose clipboard contents. Save the result promptly and clear it when appropriate.
