Finish a session on a shared device.

1. Decide whether this device is suitable

Google recommends signing in to sensitive services only on devices you trust. Chrome Guest mode separates a session from other Chrome profiles, but it does not make an unfamiliar computer safe or make browsing anonymous to websites or network operators.

Before starting, ask whether the task can wait until you have your own device. If you only need public information, avoid opening an account unnecessarily. For an essential sign-in, know how you will approve it and leave enough time to finish properly. Do not begin a complicated account-recovery process just before you must return the computer.

2. Keep the temporary session limited

On supported desktop Chrome installations, the profile menu offers a Guest profile. Google documents that closing the Guest session removes its browsing history, cookies, and site data from that session. This is a browser feature with a defined scope, not a promise that every trace of your activity disappears.

ATN suggests preparing a short list of the services and files the task actually requires. Decline unnecessary offers to save credentials, and avoid adding your full personal browser profile to a shared setup. Keep track of anything you download, create, print, or copy outside the browser, because those items need a separate review before you leave.

3. Close the task in a clear order

Finish or save the work to its intended authorized destination, then use each service’s sign-out control. Review the temporary files you created and remove your own unnecessary local copies where appropriate. Do not delete another person’s files or clear their browser profile as a shortcut.

Close the Guest session when finished. ATN’s suggested order is service sign-out, review of your temporary material, and browser-session closure. A closed tab alone is not evidence that every account session ended. If the device must be handed back suddenly, make a note of which accounts you used so you can review them from your own trusted device.

4. Review remaining account access

Google Account’s device-management page lists devices and sessions associated with the account. You can select a session and sign it out. Several sessions may share a device name; Google advises signing out all sessions with that name when you need to ensure that device’s related access is ended.

Use the service’s own account settings rather than a link in an unexpected warning message. Session names and timestamps are investigation clues, not complete explanations of who used a device. Record anything you do not recognize and follow that service’s security guidance if needed. Remote sign-out should not be treated as removal of files already downloaded elsewhere.

5. Record only the follow-up you need

For a routine borrowed-device task, a short private note is enough. Avoid turning the note into a second store of passwords or recovery codes.

Delete an unnecessary task note when it has served its purpose. The useful outcome is a completed task with known follow-up, not a blanket claim that a shared computer now contains no information about the visit.
