/preferences, at the foot of the sidebar. Each preference is kept in this browser's localStorage, for this browser only; nothing is stored on the server, and another browser starts from the defaults.

Scheduler trainsHide scheduler trains: leaves the scheduler's own trains (the job dispatcher, the manifest manager, the job runner and the cleanups) out of the run lists, the live feed, the Overview, Trains and Manifests. The same switch sits on those pages. A filter that names one of those trains still shows it.On

The credential itself is never stored: the console holds it in memory, so it is asked for again after every reload (How the app authenticates). How often the scheduler checks for work is a scheduler setting, on System.
