Your profile and active sessions
Profile and session management live in two dialogs reached from the account menu in the top right: Account, and Security and sessions.
Your profile#
Active sessions#
The Security and sessions dialog lists every session currently signed in to your account, showing the browser and operating system, the IP address, roughly when it was last seen, and a short identifier so two similar-looking rows can be told apart.
Revoking a session#
Every session except your current one has a Revoke button, and when there is more than one there is also an action to sign out all the others at once. Your current session cannot be revoked from the list; use Sign out for that.
Revocation takes effect immediately rather than waiting for a cache to expire. The next request from that device is rejected. This matters when you are removing access from a lost or stolen device.
Changing your password can also end other sessions, and completing a password reset ends all of them. See Passwords.
