❓ Frequently Asked Questions
Are generated passwords transmitted or saved on any remote server?
No. All password generation uses Web Crypto API (crypto.getRandomValues) and calculates strength entropy 100% locally in your browser. No passwords ever touch a server.
What makes a password strong?
A strong password has high cryptographic entropy. Key factors include a long character length (at least 16+ characters) and a mix of uppercase letters, lowercase letters, numbers, and special symbols.
Why should I use Web Crypto API instead of Math.random()?
Math.random() is pseudorandom and predictable for cryptographic uses. Web Crypto API provides cryptographically secure random values (CSPRNG), ensuring your passwords cannot be guessed or forecasted.
