Signed-in devices

Account, Signed-in devices lists everywhere your account is currently signed in, with the device, its address and when it was last used, and marks the one you are on. Signing out a device you do not recognise ends its session immediately, and it has to sign in again to get back. You cannot sign out the device in your hand from this list; use Sign out on the account screen for that. It is a good thing to glance at if you have signed in on a shared or public device and want to be sure it is no longer connected.
