Knowledge Base
Passwords are generated using the Web Cryptography API (crypto.getRandomValues), which provides cryptographically secure random numbers. The process runs entirely in your browser — nothing is sent to any server.
A strong password has high entropy, meaning a large character pool combined with sufficient length. Enabling all character types (uppercase, lowercase, numbers, symbols) and using 16+ characters creates a very strong password.
Entropy measures how unpredictable a password is, expressed in bits. A password with 80+ bits of entropy is considered very strong and would take billions of years to brute-force with modern hardware.
Yes. The generator uses cryptographically secure randomness (not Math.random). Since everything runs client-side and nothing is logged, you can safely use generated passwords for real accounts.
