Which is the safest file-management practice on a shared computer?

Correct answer: Use a personal account, save work and log out at the end

The governing concept is privacy and access control on a shared computer. A personal account separates one user’s files and permissions from other users, while saving work correctly and logging out prevents the next person from accessing an open session. Therefore option A is the safest practice. Sharing passwords removes accountability, a public folder exposes private files, and minimising a window does not close the session or protect data.
