Thanks for giving Duo a try! When you sign up for a new account you get to explore all the features and benefits of our Platform edition for one month. When the Platform trial expires, we switch you to the free Personal edition (unless you’ve already opted into another paid account type).
Trusted Networks is part of Duo’s Platform and Enterprise editions. That’s why the feature is no longer available to you. You can see which features are included in each edition on our Pricing page.
You can continue using Duo’s Windows Logon application on your server. You just need to approve the Duo authentication request when logging in. Make sure that you’ve enrolled a user in Duo that has the same username as you use to log on to your Windows server.
If you’d like to remove Duo from your Windows Server, you can do so from the “Programs and Features” Control Panel applet. Look for the “Duo Authentication for Windows Logon” application in the list and click to uninstall it. If you aren’t able to log on to your Windows server, even with an enrolled Duo user login, see our instructions for uninstalling Duo from Safe Mode.
