How to change hub password

From time to time I like to change some of my passwords on things, and I want to do so on my ST hub, but I can’t find how to do so. I can’t find anything on this anywhere.

On a side note, I did find where it says to change the network info, under the hub, then touch the three dots and goto network settings. When i go to the dots, there is no such option. When I go to ST settings, change device Wi-Fi network is greyed out.
