Frequently Asked Questions

How secure are the generated passwords?+
Extremely secure. The tool uses the Web Crypto API (crypto.getRandomValues) which generates cryptographically strong random values — the same standard used by security professionals.
Are the passwords saved anywhere?+
No. Passwords are generated entirely in your browser and are never sent to any server. Once you close the tab, the password exists only wherever you copied it to.
What is a good password length?+
Security experts recommend at least 12 characters, but 16+ characters with a mix of letters, numbers, and symbols provides excellent protection against brute-force attacks.
Can I use this for multiple accounts?+
Yes, but always generate a unique password for each account. Never reuse passwords across services — if one gets compromised, all accounts sharing that password are at risk.
