Secure password generator
Create a strong random password in this browser. Nothing is sent, saved or added to analytics.

Very strong
How generation works
The generator uses the browser cryptography API, avoids modulo bias and guarantees at least one character from every selected set.
Use a password manager
Entropy is an estimate, not a security guarantee. Use a unique password for every account, save it in a trusted password manager and enable multi-factor authentication.
Generated only on this device
Generation begins only when you click the button. The password is not sent to our server, written to the URL, stored or shared with analytics.
Frequently asked questions
Does this tool send my input to a server?
No. The tool runs in this browser after you choose to use it. Your pasted content or generated result is not added to URLs, storage, analytics or server requests.
Does a clean result guarantee that an email or account is safe?
No. These tools explain technical clues and reduce routine risk, but they cannot replace your judgment, malware protection, account security controls or advice from a qualified security professional.
