How strong are these passwords?

A 16-character password using uppercase, lowercase, numbers, and symbols has over 95^16 ≈ 440 quintillion possible combinations. That's extremely strong against brute-force attacks.

Are generated passwords stored anywhere?

No. Passwords are generated entirely in your browser using the Web Crypto API. Nothing is sent to any server.

What makes a password strong?

Length matters most. A 16+ character password is much stronger than a short complex one. Using all character types (uppercase, lowercase, numbers, symbols) further increases entropy.

Should I use a password manager?

Yes. Strong passwords are hard to remember — use a password manager like Bitwarden, 1Password, or your browser's built-in manager to store them securely.
