Vulnerability Hygiene Checklist

1. At least 12 characters long (NIST standard) [FAIL]
2. Free from compromised wordlist [FAIL]
3. Contains uppercase letters (A-Z) [FAIL]
4. Contains lowercase letters (a-z) [FAIL]
5. Contains numerical digits (0-9) [FAIL]
6. Contains special symbols (!@#$...) [FAIL]
Entropy Factor: Entropy represents mathematical security. Doubling the length is significantly more secure than adding exotic symbols to short passwords, as proven by NIST.
