How does Duo Desktop work?

Duo Desktop will check your computer for and flag items that are missing or out-of-date:

An example of a successful health check will show all green checkmarks
(image from a from a macOS device):
Screen displaying all green check marks for your computer system that passes health checks

An example of a failed health check will show one or more red checkmarks
(image from a from a Windows device):Screen displaying a mix of green and red check marks for your computer system so it does not pass all health checks

 

My computer failed the Duo Desktop health check. What do I do now?

You will need to fix the issue preventing you from logging in. Don’t worry, the Duo application will provide links to help you fix the issue. Review the health check results to see what failed. Examples:

While an outdated operating system will not prevent you from logging in, it is a problem that needs to be fixed. If your operating system is out of support (meaning it is no longer supported by the vendor), your login will be denied. In either case, report the problem to the IT help desk for assistance.
