Settings → Security shows every browser and device that's currently signed into your account, with the last activity time and rough location for each. Use it to:
- Confirm only you have access — anything you don't recognize, revoke immediately.
- Sign out a borrowed device you forgot to log out of.
- Sign out everywhere at once after a security concern, without losing access on your current device.
The row for the device you're currently using is tagged This deviceand can't be revoked from itself — use the regular Sign out button at the top of the app instead.
