Sessions

A session is one signed-in device or browser. You stay signed in for up to 30 days of inactivity on each device, and you can review and revoke your sessions at any time.

See where you are signed in

Settings → Account lists your active sessions — each with the device or browser, the time it was last seen, and the network address it last used. The session you are using right now is marked This device, so you can tell it apart from the rest.

Sign out

Two controls sit beneath the list:

• Sign out — ends the current session only. Other devices stay signed in.
• Sign out of all devices — ends every session, including this one, and returns you to the sign-in screen. Use it if you signed in on a shared or lost device, or just want a clean slate.

How revocation takes effect

Sessions are checked on the server on every request, so signing out — on one device or all of them — takes effect immediately. A revoked, expired, or suspended session is rejected the next time that device asks for a page, with no waiting for a cached login to lapse. The same is true the instant an account is closed: every session stops working at once.
