- Maintaining session security on public devices

Log out of every account before leaving a public computer. Research from the Ponemon Institute indicates that 68 % of data breaches involving shared terminals are traced back to sessions left open. Immediate logout cuts that risk dramatically and requires no additional software.

Activate private‑browsing mode on every visit, then clear the cache and cookies before you walk away. Browser extensions that store passwords should be disabled on public machines; instead, rely on a hardware token or a mobile authenticator for one‑time codes.

Configure account settings to enforce short idle timeouts–most services allow you to set a limit of five to ten minutes. When a timeout occurs, the session ends automatically, preventing a passerby from reactivating it. Pair this with two‑factor authentication; even if a session is hijacked, the attacker still needs the second factor.

Consider using a trusted VPN connection from your phone or personal device while accessing sensitive sites on a public terminal. A VPN encrypts traffic, making man‑in‑the‑middle attempts far less likely to succeed. Also, verify the URL starts with https:// and look for a padlock icon before entering credentials.
