Render as User on Windows - store password?

Hello,
We are looking into pushing a “render as user” workflow on our windows renderfarm.
https://docs.thinkboxsoftware.com/products/deadline/10.1/1_User%20Manual/manual/environment.html#user-account-settings

According to the docs, ONLY on windows, we will have to store each user’s unique password?

The user account settings used to start the rendering process are stored in the User Settings for each user. For Linux and OS X, only the User Name is required. For Windows, the Domain and Password must also be provided for authentication.

Has anyone here done that/found a way to automate storing those unique passwords per user?

Thanks,
-Jake
