Security tips

- Never reuse passwords. Use a password manager like Bitwarden or 1Password to store them.
- Truly random. This tool uses
crypto.getRandomValues()— not Math.random(). - Works offline. Generation is 100% in-browser. No network calls.

Avoid using personal information such as names, birthdays, phone numbers, or common dictionary words. Each online account should have a different password to reduce security risks.
