The VMware Identity Manager service includes a default access policy that controls user access to their VMware Identity Manager resources.

The authentication session length configured in the policy rules determine the maximum amount of time users have since their last authentication event to access their apps launcher page or to launch a specific Web application. The default is eight hours. After users authenticate, they have eight hours to launch a Web application unless they initiate another authentication event that extends the time.

You can edit the default policy to change the session length from the VMware Identity Manager administration console, Identity & Access Management tab, Manage > Policies. See the VMware Identity Manager Administration guide, Managing Access Policies.
