Using special characters in the password is not required, but it is
allowed. Also, the system keeps a history of the user's previous two
passwords, and their reuse is not allowed.

With this command, the user is first prompted for his/her old password.
If the "*Current Password*" is correct, then the user is asked twice for
a replacement password ("*New password*"). The replacement password
needs to fulfill the HCC password requirements.
