When the web client has been idle for 20 minutes or longer, the user may get automatically logged out.

The default auto-logout time is 20 minutes of inactivity, unless the user has a tab with a refresh page open.

The activity timeout value can be set by the OSM System Administrator.

In the config.yaml, there is an activityTimeout setting that controls how many minutes of inactivity OSM will wait before logging out the user.

The following pages will stop automatic logout:

Explanation of scenarios where user will or will not be logged out.

Scenario 1 - Only one tab with a refresh page

User opens OSM Web Application in a browser with only one (1) tab containing an OSM page.

Scenario 2 - Only one tab with a non-refresh page

User opens OSM Web Application in a browser with only one (1) tab containing an OSM page.
