A laptop sold months ago and a browser used in a hotel can both remain in an account’s recent-device list. The list deserves a calm review: an unfamiliar line is a reason to inspect details, not automatic proof that somebody broke in.
A device and a session are not the same thing
Open your Google Account, choose Security & sign-in, then Manage all devices. Google may show devices and separate sessions. A session is a period when a browser, app or service was signed in. One computer can therefore appear several times after using another browser, verifying a password again or opening a private window.
The displayed time is the last communication with Google. Background synchronisation can make it newer than the last moment you remember touching the device.
Compare details before deciding
Open each doubtful entry. Compare the device type, browser, approximate location and recent time with your own activity. Locations can be approximate, and a factory-reset device can remain visible for a while.
For an old computer you no longer own, sign out. If several sessions share the same device name and you cannot identify them confidently, Google recommends signing out of all those sessions.
Treat a real surprise as an account event
After signing out, refresh the list and record only the device name and date if you need a note. Do not save screenshots containing account details unnecessarily.
If the device or activity is genuinely not yours, use the provider’s account-security process rather than repeatedly signing out one line. Review recovery methods and recent security activity as part of the same incident.
