Online Chat on Shared Devices
Online chat on shared devices needs a little more care than chatting on your own phone. Think about who can use the device after you and what the browser may keep. You can always wait until you have more privacy.
Decide whether to sign in at all
A public or borrowed computer may have settings you cannot inspect. If the conversation can wait, use a device you control. That is especially sensible for account recovery or anything involving sensitive information.
If you do use a shared device, avoid saving your password there. Read any browser prompt before accepting it. A convenient login now can leave access available to the next person who opens the browser.
Check what is visible while you chat
The screen is one part of the picture. Notifications can also appear over another window, and a preview may reveal a message even when the site is no longer in front. Review the relevant controls before enabling alerts.
The notification guide explains how to think about message previews. Keep the room around you in mind too. An account setting cannot stop somebody nearby from seeing an unlocked screen.
Avoid leaving extra copies
Be deliberate about downloads or screenshots. They may remain outside the browser session. If you need to save something for support, choose a location you control rather than a shared downloads folder.
Private browsing can help with some local browser traces, but it has limits. Read the private browsing guide before relying on it. It does not make a managed work computer or an unfamiliar device fully private.
Sign out before handing the device back
Use the site’s sign-out control. Closing a tab alone should not be treated as confirmation that the account session has ended. Check the browser’s password storage if you accidentally accepted a save prompt.
What if I forgot to sign out?
Use the service’s account access controls or official support from a device you trust. Explain which device you used and when, without giving another person your password.
Should I use the same password everywhere for convenience?
No. Use a unique password for the account. A password manager on your own device can make that easier without leaving the login on a shared computer.
