Hello Piotr!
I don't quite understand what it is that you are trying to accomplish.
Do you mean a user account other than yourself, the
Admin, must change the password every 60 days? And you somehow want the Mac to force this action?
If so, I'm not aware of a method to do that, but an
Admin user, can change the user passwords manually.
Info here
Changing or resetting an account password.
