Storing passwords and using them in a team. What are you using?

Question

Passwords

What is the point? There are n people who should have access to one cross-platform service (OSX, Linux, Windows. Yes, we have a motley team :) ) that allows you to store passwords preferably not in the cloud, separate passwords into categories and regulate people's access to these categories.
It would also be cool to have a tool that can version passwords. Who, when, why, what changed.

Answer 1

Similarly, in search of a similar solution. Now we use KeePassX, but this thing is not suitable for collective use. There is also TeamPass, but it is almost non-existent. Alternatively, you can use online services, but somehow you don’t want to give out your passwords.
