I think you are asking "when can I use my windows credentials to login to Quarantine?", and if that is true then you already can. This is what we refer to as "Federated Login" and requires some set up by your organisation. That setup is described here -
Federation and Single Sign-on for the ClientNet Portal. The document relates to the ClientNet portal, but after those steps are complete the same mechanism means that users will be able to login to the Quarantine portal using their windows credentials.

Customers sometimes wonder about that there will come windows user authentication talent to login ES cloud quarantine ? Do you think this development will be in ESC for the future as an enhancement.
