That was a misunderstanding, so to view creation, modification changes you have to setup SMTP in the passbolt config file /etc/passbolt/passbolt.php
To view who read the password and used it, I am not too sure if passbolt registers that. It may be in the Enterprise edition.
I have not personally used the Enterprise edition so I’m not too sure if there is that feature.
Unfortunately Passbolt may not be able to do that since its only a Password Manager.
This problem can be solved by probably placing cameras in the location where you store the password and only trusted people can enter that room/safe.
