About Password Security
This tool generates cryptographically secure passwords using your browser built-in crypto API. All password generation and strength testing happens locally in your browser - nothing is sent to any server.
Password Strength Scoring:
- Very Weak (0): Easily guessable, avoid using
- Weak (1): Vulnerable to attacks, not recommended
- Fair (2): Better but still could be improved
- Strong (3): Good password, reasonably secure
- Very Strong (4): Excellent password, highly secure
Best Practices:
- Use at least 12-16 characters for important accounts
- Include a mix of uppercase, lowercase, numbers, and symbols
- Never reuse passwords across different accounts
- Consider using a password manager to store passwords securely
- Enable two-factor authentication (2FA) when available
