I would like to do exactly what this poster wants to do:

When a LUKS encrypted partition pops up the unlock window it gives 3
options for how to remember the password. The "Remember password until
you logout" is always ticked by default. Is there a way to make
"Forget password immediately" the default?

Enter a passphrase to unlock the volume:
[] Forget password immediately
[x]Remember password until you logout
[] Remember forever

Unfortunately, there hasn't been any answer to this question, so I created a new question. (Let me know if I wasn't supposed to do it this way!)

I was looking for the same thing, but judging from a similar question that was answered on StackExchange, there isn't a way at present. It looks like the default behavior was changed from "Forget password immediately" to "Remember password until you log out", but absent some way to tweak this, the new default isn't going to work for some of us either.

Hope this helps!

There is no out of the box way to change the default for this menu option. However, there is a work around, where you create a script to detect X window and then have the system send an alt+i signal that will switch it to immediately forget.

You can also set up a script to udiskctl --lock --unlock the drive, which will get rid of the file manager integration, thus the security risk, of saving it to the keyring, if by a non-root user.

As for me,
udisksctl unlock -b /dev/sdb1 #Decrypts usb and mounts it
umount -l /media/john/usbfolder Lazy umount with mapping equal to mounted path
udisksctl lock -b /dev/sdb1 Encrypt the usb

It gets a little more complication since the dialog window does not have a lot of metadata to manipulate with X.
