Web Page Listing Current Log Ins
Improve account.adobe.com to provide a list of computers that your account is currently being used to license, and the ability to deactivate those licenses. This is currently not possible without trying to log into the Creative Cloud application on a third computer. This functionality is available with other similar SAAS such as Microsoft Office.
