For details on the password screening mechanism, of the reserved password database (VMS$PASSWORD_DICTIONARY.DATA), and details of how to merge your list of prohibited passwords into the database, please see the associated chapter in the OpenVMS security manual.

The password filter permits you to establish particular and site-specific password requirem
