Best practices for password security
Use Unique Passwords
Never reuse passwords across different accounts. Each account should have its own unique password.
Make It Long
Longer passwords are exponentially harder to crack. Aim for at least 12-16 characters.
Use Random Characters
Mix uppercase, lowercase, numbers, and special characters for maximum security.
Avoid Personal Info
Don't use names, birthdays, addresses, or other personal information that can be easily guessed.

FAQ
1. What makes a password "Very Strong"?
A "Very Strong" password typically has a high entropy score, uses a mix of all character types, and would take centuries to crack using modern methods.
2. Is it safe to type my real password here?
Our tool processes everything locally in your browser. However, for maximum security, we recommend testing variations of your password rather than the exact one you use for sensitive accounts.
3. Why does "Time to Crack" matter?
This metric estimates how long it would take a computer to guess your password using brute force. The longer the time, the more secure your account.
This Password Strength Checker is for educational and informational purposes only. While our tool uses advanced algorithms to estimate security, no automated test can guarantee 100% protection against all cyber threats. We never store your passwords, but we advise users to avoid entering their most sensitive credentials into any third-party online tool.
