Calculate password strength and entropy for security analysis
About Password Entropy
Password entropy measures the randomness and unpredictability of a password. Higher entropy means the password is more secure and harder to crack. This calculator helps you understand the strength of your passwords.
Password Security Tips
- Length: Longer passwords are generally more secure
- Complexity: Use uppercase, lowercase, numbers, and symbols
- Unpredictability: Avoid common patterns and dictionary words
- Uniqueness: Use different passwords for different accounts
- Entropy Target: Aim for at least 50-60 bits of entropy
- Password Managers: Consider using a password manager for strong, unique passwords
