Advanced Password Security and Entropy
When protecting sensitive data, true security comes from entropy—the measure of unpredictability. PassGen Pro uses the built-in Web Crypto API to generate cryptographically strong random values that are statistically impossible to guess. By using our advanced options like Strict Mode and Similar Character Exclusion, you ensure your credentials meet the highest international security standards.
Why Length Matters More Than Complexity
Security research shows that password length is the primary factor in resisting brute-force attempts. While adding symbols is helpful, a 20-character password is exponentially harder to crack than an 8-character one. We recommend generating keys with at least 16-20 characters for banking and primary email accounts.
| Entropy Level | Security Rating | Estimated Crack Time |
|---|---|---|
| < 45 Bits | Insecure | Minutes |
| 45 - 80 Bits | Moderate | 1-10 Years |
| 80 - 128 Bits | High | 1 Million+ Years |
| > 128 Bits | Extreme | Eternity |
Best Practices for Account Protection
- Unique Passwords: Never reuse the same password across multiple sites.
- Use a Secure Vault: Store your generated passwords in a reputable manager like Bitwarden or 1Password.
- Enable 2FA: Multi-factor authentication is your second line of defense.
