Why Length is the #1 Security Metric
NIST SP 800-63B guidelines place character length above all other requirements. While character complexity rules can be gamed with predictable human substitutions, length cannot be cheated.

Frequently Asked Questions
Why does password length matter so much?
Every additional character multiplies the total combinations by the size of the character pool (up to 95x). A 16-character password has over 1.4 × 10^14 times more combinations than an 8-character password.
