Frequently Asked Questions
How are the passwords generated?
Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same API used by password managers.
What makes a password strong?
Password strength depends on length and character variety. A 16+ character password using uppercase, lowercase, numbers and symbols is considered very strong. Length is the most important factor.
Is it safe to generate passwords online?
Yes. Passwords are generated using cryptographically secure random number generation. No passwords are stored or logged.
