Active sessions
Use My preferences > Security and authentication > Active sessions to protect your account when QuickStart may still be open on another device. The page does not list devices individually; it provides one action that signs out every other session while preserving the session on your current device.
QuickStart does not display a list of individual signed-in devices in this section. Instead, it provides Sign out of all other devices, which invalidates every other active session while keeping the session on your current device active.
Use this action if you lose a device, use QuickStart on a shared device and forget to sign out, or suspect that another person has access to your account.
