Frequently Asked Questions
Is it safe to generate passwords in the browser?+
Yes. Passwords are generated exclusively on your local machine using the Web Crypto API (crypto.getRandomValues) with zero server transmission.
What is the recommended password length?+
Security authorities recommend at least 16 characters including uppercase, lowercase, numbers, and symbols to resist modern brute-force GPU attacks.
Can generated passwords be recovered if lost?+
No, because passwords are never logged or stored on any server.
