Ensure Password Minimum Length Is Configured

높음레벨 1자동macos

설명

A minimum password length is the fewest number of characters a password can contain to meet a system's requirements. Ensure that a minimum of a 15-character password is part of the password policy on the computer. Audit: Reads the length from the policyAttributePassword matches .{N,} policy (or a minimumLength/minChars value); N must be >= 15.
