The RSA Authenticate app for Windows 10 is only available from the Microsoft Store. If your organisation has a specific requirement that means the Microsoft Store is not suitable, we'd encourage you to let us know via the RSA Ideas for the RSA SecurID® Suite page.
As of the August 2019 Release, you can now obtain and distribute the app using Deployment Image Servicing and Management (DISM) tool. Check out my blog about the August release for more details.
