One place for what is now scattered
Most people keep their important details in many places at once: in their inbox, in folders on the computer, in a drawer and in their head. For you, that usually works fine. For someone who has to help you, it quickly turns into a search.
A digital vault brings that information together. Not as a pile of loose files, but organised by topic. That way, someone else quickly sees what there is and what needs to happen.
