How can I log out of a trading account from all devices?

Most trading apps have a security or session management section under account settings that shows all currently active login sessions, often by device type and last active time, with an option to log out of one specific session or all sessions at once. If you can’t find this option within the app itself, changing your account password is a reliable fallback, since most trading platforms automatically invalidate all existing sessions once the password is changed, forcing a fresh login everywhere. You do this immediately if you suspect unauthorised access, like a login notification you don’t recognise or a device you don’t remember using, rather than just changing settings on the one device you’re currently using, since the goal is to cut off any session you’re not actively aware of.
