DT3 doesn't ask for database password

I created a related issue some time ago where we talked about DEVONthink 3 opening databases without asking a password.

Sparse encrypted database in DEVONthink 3

Earlier I’ve used Knox from Agilebits to open encrypted vaults that contain DEVONthink databases for sensitive information. The vaults are stored on disc as sparse image file. It’s a bit of hassle to open first the encrypted vault and then open the database in DEVONthink, so I was intrigued to try the encrypted database option in DEVONthink 3. However, despite its extension .dtSparse, it stored the database as a “block” image. It’s an issue when working with a database of this kind at least when…

After this post, I tried to create a new “sparse bundle” database with the Disk Utility technique, just two days ago and right before this post. The thing still happens on my Mac; DEVONthink 3 open the encrypted database without asking any password. It can’t be that I’ve made some mistake of not encrypting the database in the first place, or saving it to the Keychain Access all over again - I’m pretty careful with things like this. And I checked from the Keychain Access that I haven’t stored the newly created password there. Yet DEVONthink 3 keeps opening the new database without asking any password. It does this even if I close DEVONthink 3 app. Only after a reboot it asks for the new password. The mount appears and disappears in /Volumes/. I don’t understand how the DEVONthink 3 can mount and unmount the encrypted volume without asking for the specific password for the volume. It’s encrypted with the Mac File Utility, it disappears from the Finder and /Volumes. Yet DEVONthink 3 can open it without a password, even after restart of the Application, unlike other applications. Please explain.
