Are database administrator passwords vulnerable to security when changing them from the command line?

I have a question during the initial setup of MariaDivi.

In the above article

It is important to make a habit of changing passwords in the command line, such as "mysqladmin password". This is because passwords can be easily exposed when other users use the "psaux" command or look at the history file (~/.history, ~/.bash_historyetc) when working on the server.

That's what it says. Doesn't the mysqladmin utility eventually leave a log because it's input from the command line?
