Frequently Asked Questions
- How is password strength calculated?
- Password strength is calculated based on length, character variety (uppercase, lowercase, numbers, symbols), entropy, and resistance to common attack patterns. The score considers multiple security factors.
- Is it safe to check my password here?
- Yes! All password analysis happens locally in your browser. Your password is never transmitted to any server or stored anywhere. The tool works completely offline.
- What makes a password strong?
- A strong password has at least 12 characters, includes uppercase and lowercase letters, numbers, symbols, avoids common patterns, and doesn't use dictionary words or personal information.
- How accurate is the 'time to crack' estimate?
- The estimate assumes a brute force attack at 1 billion attempts per second. Real-world cracking times can vary based on attack methods, but it provides a good relative comparison.
- Should I use the generated passwords?
- The generated passwords are cryptographically secure and suitable for use. However, consider using a dedicated password manager for storing and generating passwords across all your accounts.
