Multiple Web Sessions

Select System Configuration > Security.

This setting is enabled by default, and allows the user to run FME Flow sessions from multiple web browsers simultaneously.

When disabled, FME Flow restricts the user from running multiple FME Flow sessions simultaneously. If the user logs in to FME Flow from another browser instance (including incognito) while existing session tokens are enabled, those tokens are disabled, and a new session token is created from the most recent login. The user is effectively logged out from any previous FME Flow sessions on other browsers.

You must click Save for any changes to take effect.
