⚙️ How This Tool Works Locally
When you use this tool on PrivacyKit, every byte is processed directly in your device RAM.
- 1. No Network Traffic: No HTTP POST or PUT requests are made to any server. Your internet can even be disconnected.
- 2. Modern Native APIs: Computation uses native HTML5 Canvas, Web Cryptography (SubtleCrypto), and client-side binary parsers.
- 3. Zero Footprint: Closing this browser tab immediately frees the memory buffer. No persistent cookies or caches remain.
💡 Frequently Asked Questions
Why is a browser CSPRNG safer than typical online password generators?
Most online generators create passwords on their server and send them to you over HTTP, meaning the server operator could potentially log your new password. PrivacyKit generates passwords 100% locally using crypto.getRandomValues().
What is Shannon entropy and why does it matter?
Entropy measures the mathematical unpredictability of a password in bits. A password with 80+ bits of entropy would take billions of years to crack with modern supercomputers.
How long should my passwords be in 2026?
Security standards recommend at least 16 characters for standard accounts and 20+ characters for master passwords and root admin credentials.
Can I exclude confusing characters like 0 and O?
Yes. Simply toggle the "Avoid Ambiguous Characters" switch to remove easily confused letters and numbers.
Does PrivacyKit save or remember my generated passwords?
No. We have zero database and zero analytics. Once you close the tab, the password exists only where you saved it.
