Password Control Configuration 579
Configuring History
Password Recording
With this function enabled, when a login password expires, the system requires the
user to input a new password and save the old password automatically. You can
configure the maximum number of history records allowed for each user. The purpose
is to inhibit the users from using one single password or using an old password for a
long time to enhance the security.
■
When the system adds a new record but the number of the recorded history
passwords has reached the configured maximum number, the system replaces the
oldest record with the new one.
■
When you configure the maximum number of history password records for a user,
the excessive old records will be lost if the number of the history password records
exceeds the configured number.
■
When changing a password, do not use the recorded history password; otherwise,
the system will prompt you to reset a password.
The system administrator can perform the following operations to manually remove
history password records.
