Sessions show your recent sign-ins and where they occurred. If you notice unfamiliar activity or recently used a shared device, choose Sign out everywhere to secure your account.
Click on your profile → Security.
Click 'Sign out from all devices'.
You’ll be signed out everywhere including in your current device.
Tip: Sessions also time out automatically after a period of inactivity. If you’re asked to log in again, that’s expected and helps keep your account safe.
