How do admins change own password?

Distro 12.0.11… Maybe I’m missing something simple but how does an admin change their own password?

(that is without access to the admin module where they could change their own security settings)

Paradox,

If you don’t have gui access why do you need to change the gui password.
If you have gui access why not change it through the gui

How can they change it without access to the admin module where they could change their own security?

If you loose/forget the password you can gain access with

amportal a u <session>

That’s not really what I am asking. Lets say I create an admin for user “Sandy”. Sandy has access only to module CDR. At some point Sandy decides for security reasons that she needs to change her password. How does she do it?
