PRACTICAL CHECK

Know which session you are leaving behind.

  1. 01

    Sessions

    Identify browsers or apps signed in to your account.

    What this tells you

    You have identified your own signed-in browsers and apps on the shared device.

    A tab, browser profile and separate app may represent different places to check. Inspect only accounts and devices you are authorized to manage.

  2. 02

    Sign out

    Sign out before handing over shared hardware.

    What this tells you

    The intended session no longer opens your account after sign-out.

    Read the current sign-out prompt. Check your own saved-login choices and files separately; closing a tab is not a sign-out confirmation.

  3. 03

    Protect

    Review account security if you find an unfamiliar session.

    What this tells you

    An unexplained session receives a security review, not just a cosmetic cleanup.

    Compare the device and time with your own use. If you see unauthorized account changes, follow official owner recovery.

COMPARE THE EVIDENCE

Closing, locking and signing out differ.

Action or itemWhat it addressesWhat remains to check
Close a tabRemoves that view from the screen.Whether the browser remains signed in.
Lock the deviceLimits immediate use while you are away.Your session when authorized use of the computer ends.
Sign outEnds the selected account session through its official control.Other browsers/apps and any saved-login choices.
Saved files or credentialsYour own data retained outside the live conversation.Remove only items you own or are authorized to manage.
PUT IT IN CONTEXT

From an open session to a checked handover.

A remembered session on a borrowed laptop can matter as much as a phone preview.

YOUR NEXT DECISION

Before handing over the computer.

Confirm the intended session

Review the current session list and the browser you used. If a device is unfamiliar, compare its context before drawing conclusions.

Review session evidence →

Keep your recovery route available

Before ending the only session with needed readable history, understand your own storage and recovery situation.

Review recovery readiness →

Check information outside the chat

Consider browser notifications, connected displays and your own downloaded files. A sign-out is not proof that every copy disappeared.

Check display exposure →

A handover check has a specific target.

Confirm the account, browser/profile and session you meant to end. Use the official service to verify the state; never test whether somebody else’s saved access still works.

A LIMIT THAT MATTERS

Keep this boundary.

Only inspect devices and accounts you are authorized to manage.

Do not erase another person’s browser profile or inspect their saved credentials. Limit cleanup to your own information and permissions.
