Sharing a computer without sharing every account
A shared laptop can slowly become everyone's email, shopping account, saved documents, and open browser sessions mixed together. Nobody needs bad intentions for a wrong click to expose something private or place an order from the wrong account. Separate user profiles seem obvious, but keeping them working in a busy household can take a little organisation. What arrangement is simple enough that everyone actually follows it? This is especially worth discussing where children, visiting relatives, or several people working from home use the same machine at different times.
