I would like mattermost to behave in such a way that when a user closes the browser, (s)he is automatically logged out
I've found the section about how to manipulate the session configuration in the docs (https://docs.mattermost.com/administration/config-settings.html?highlight=session#sessions) but it seems i can only set a fixed amount of days? That means when a user completely switches of the computer and boots it again (s)he is always automatically logged in to mattermost. I find that very undesirable for the web-interface since it might be used on computers that are shared.
Is there really no way to tell mattermost it should set a session cookie? (so that the session gets destroyed when a user closes the browser)
