For those who are ignoring this because it's a SHOULD: On April 1, it
changes to a SHALL.

Subject: [Servercert-wg] Routine password changes



Just a reminder that effective April 1, 2020, the new rules about routine
password changes go into effect (SC3).  CAs should examine their password
policies, and make sure they are not requiring password changes more often
than every two years.


This does not apply to non-routine password changes.  If a password is
compromised, or needs to be changed for any other reason, it can be changed,
regardless of its age.  As the requirements state, "If the CA has any policy
that specifies routine periodic password changes, that period SHOULD NOT be
less than two years."


This is to prevent users from selecting passwords like "Spring2020!" or
"Pass4/20", where half of the password is easily guessable due to attempts
by users to cope with overly frequent password changes.




P.S. Compromising all your passwords every 90 days is not a reasonable way
of complying with both this requirement and other schemes that require
periodic changes :P  Figure something else out.
