Enforce Stronger Passwords

NIST’s new guidelines on password strength published in Special Publication 800-63B now recommend that all applications with user accounts “compare the prospective secrets against a list that contains values known to be commonly-used, expected, or compromised.” NIST recommended this extra check due to the modern success rate of brute force and credential stuffing attacks.
