Team login licenses are accessed through the Licensing dialog that appears when you open a Foundry application that is not tied to a license.

Once a Team License is activated, a reference to all of the selected organization's team licenses is stored on your machine. Running applications you have access to automatically fetches licenses when the product runs and return them when you close it down.

For example, if you first activate your team licenses from Nuke, but you also have access to Nuke Studio licenses, when you run Nuke Studio you automatically fetch a full Nuke Studio entitlement - nuke_i, nukex_i and nukestudio_i.
