Do you have proposed modifications that would address these questions?  I would be happy to incorporate them.

 

 

How about this:

 

  iv.         Frequent password changes have been shown to cause users to select less 

               secure passwords.  If the CA has any policy that specifies routine periodic password changes, 

               that period SHOULD NOT be less than two years.  Effective April 1, 2020, 

               if the CA has any policy that requires routine periodic password changes, that period SHALL NOT 

               be less than two years."

How are the concerns that were raised by Microsoft (copied below for reference) addressed in this version? If the intent is for the language in section 2.g(iv) to only apply to periodic, policy-driven password changes and not to prevent event-driven changes, I think that should be clarified.

 

* How would auditors verify and prove that a CA did not change a password more frequently than two years? This is trying to prove a negative.
* What about when a CA employee leaves who knows the password which requires it to be change in less than two years?
* What about if the password is compromised and needs to be changed in less than two years?
