Password Requirements for Different Types
of Accounts
Five types of user accounts are available on OpenVMS systems:
Accounts secured with passwords that
you or the security administrator change periodically. This account type
is the most common.
Accounts secured with authentication cards that
have your password programmed onto the device. Many third-party
products support this type of authentication mechanism.
Accounts that always require passwords but prohibit
you from changing the password. By locking the password (setting
the LOCKPWD flag in the UAF record), the security administrator
controls all changes made to the password.
Restricted accounts limit
your use of the system and sometimes require a password.
Open accounts require no
password; the password is null. When you log in to an open account,
the system does not prompt you for a password, and you do not need
to enter one. You can begin entering commands immediately. Because
open accounts allow anyone to gain access to the system, they are
used only at sites with minimal security requirements and should
normally be set up as restricted accounts.
