How can I review which devices are currently signed in to my account?

Start with the account settings for the service itself, preferably by opening its official app or typing its known address yourself. Look for a section called something like Devices, Sessions, Security, or Where you’re signed in. The exact label and what the list includes depend on the service.

Read the page’s explanation before drawing conclusions. A device list might represent app-linked devices rather than every browser session. For example, Dropbox says its Settings > Security > Devices list covers computers, phones, and tablets linked to its app; signing in to dropbox.com alone does not add that device to this particular list. [S1]

For Dropbox, open Settings, then Security, and review Devices. Dropbox says account holders can see app-linked computers, phones, and tablets there, and can log a listed device out remotely using the same account controls. [S1]

Keep the scope in mind: that list is not a complete record of every way someone might have signed in. In particular, a sign-in to dropbox.com by itself does not add that device to the app-device list. [S1] Use Dropbox’s own account controls and explanations rather than assuming another service has the same layout or list behavior.

Compare the entry with devices and app installations you actually use. Consider the device type or description shown, whether you still use that device, and whether it could be an older device you forgot about. Treat the displayed details as clues, not proof: a label may be unfamiliar without identifying who used the device, and the list may not cover every session.

For example, you might note: “Phone entry: possibly my previous phone; I’m not sure. Check which phone I currently use before taking action.” That is more useful than marking every unfamiliar label as unauthorized.

First, pause and check the service’s help text for what that entry means and what its sign-out control will do. If you decide the listed device should no longer have access, use the sign-out option provided in the official account settings. For Dropbox, remote logout of a listed device is available through its Devices controls under Settings > Security. [S1]

If you cannot tell what an entry means, or the controls do not match the service’s instructions, consult that service’s official support information before acting. This review can help you spot entries to investigate; it cannot establish who used a device or guarantee that the list shows every active sign-in.

Use this as a short working note while you review the list:

Service: [service name] Date reviewed: [date] Official settings path: [section names] Entry shown: [device/session description as displayed] Do I recognize it? [yes / no / unsure] What did the service say this list includes? [brief note] Action: [no change / signed out using official control / checking official help]

For instance, “Dropbox; [date]; Settings > Security > Devices; [phone description]; unsure; list covers app-linked devices; check whether this is my current phone.” Avoid copying more account information into your note than you need.
