I have an encrypted, password-protected sparsebundle that I occasionally mount and unmount from the terminal. I want the system to ask for the password every time I mount it, but for some reason it keeps remembering.
This is how I mount it: hdiutil attach ~/path/to/my/bundle -mountpoint ~/my/mountpoint
These are some of the ways I've tried to unmount it:
hdiutil detach -force ~/path/to/my/bundle
hdiutil detach -force /Users/me/path/to/my/bundle
hdiutil eject -force ~/path/to/my/bundle
diskutil eject ~/path/to/my/bundle
diskutil unmount force ~/path/to/my/bundle
(I've read here that hdiutil unmount is not sufficient to make the system forget the password.)
However, whatever I try, the system "helpfully" remembers the password each time.
Only when I use the eject button in Finder, does the system forget the password.
Also, there is no entry in my keychain that suggest the password has been cached. (At least, I can't find it. There are none with kind disk image password.)
I've even created a new sparsebundle, with a new name and a different password, but the problem persists.
What am I missing here? How can I make sure the sytem always asks for the password, each time I mount the sparsebundle?

In this post the following procedure was suggested: "I had to first use
– harrymc – 2018-11-29T10:04:03.787unmount forceoption, then open the volume again in the script, then eject it. And that worked."Tried it, but sadly doesn't work for me. – jqno – 2018-11-29T13:26:24.733
Using detach, then closing the terminal session. Will opening a new terminal session still allow you to mount without password? – Elmo – 2018-11-29T15:46:10.817

@Elmo Nope. Only the eject button in finder seems to work reliably so far. And rebooting the system. – jqno – 2018-11-30T10:50:42.130
What version are you running? On El Capitan, "hdiutil eject ~/my/mountpoint" (note not "~/path/to/my/bundle" as in the question) results on password prompt on all subsequent "hdiutil attach ~/Documents/Test.sparsebundle -mountpoint ~/my/mountpoint" – lx07 – 2018-12-04T15:50:18.023
@lx07 I'm running Mojave. – jqno – 2018-12-05T08:46:47.277
@lx07 I just gave it another shot with the exact same commands that you mention, but still no dice... – jqno – 2018-12-05T08:49:56.667
