3.1.1.1 Password Authenticators

Passwords SHALL either be chosen by the subscriber or assigned randomly by the CSP.

If the CSP disallows a chosen password because it is on a blocklist of commonly used, expected, or compromised values (see Sec. 3.1.1.2), the subscriber SHALL be required to choose a different password. Other composition requirements for passwords SHALL NOT be imposed. A rationale for this is presented in Appendix A, Strength of Passwords.
