Click on 'Account' in the upper right corner
Click 'My account'
Click 'Active sessions'
On this page you will find a list of all active login sessions for the account you are logged in as. This makes it easier for you to check if there are any unauthorized logins. Every active login shows the IP address, device information (OS, OS version, browser), location and date. The current session is indicated with 'This session'.
If you want to log out of a specific session, you can click the garbage bin icon next to the session. You can also log out of all sessions except the current one by clicking the button ‘Deactivate all now’ at the top of the page.
If you change your password while logged in, all sessions except the current one will be automatically logged out. Changing your password via the password reset mail logs out all sessions.
