share the password database, do not add passwords at the same time in multiple places, always sync->add->sync. Most people do not add passwords often, so that works just fine. You also can have multiple database file, one for the common shared password which is always read only synced from a single source. And one for local passwords which are not yet, or should not, go into the shared database.
