Hey @kivenage
Yes, you can absolutely test with a group of users using Duo Policy! You’ll want to start with the New User Policy, which controls authentication for users not enrolled in Duo, and Authentication Policy (formerly Group Access Policy) to change how both existing Duo users and unenrolled/new users access a Duo-protected application. If you’re interested in doing a phased rollout, this can also be achieved with policy, specifically using Group Policy.
You might find Duo Level Up beneficial, as well. It’s our customer education platform currently in beta that offers a variety of courses and two certification tracks, with more being added. It covers topics such as this, and we are working on a Policy course as we speak! Sign up for Level Up here if you like.
