Contacting Support

How should you get in touch with us?

Our Support Portal is available to all paying customers via the left sidebar of the Admin Panel. Use the portal to securely transmit attachments, view your current and previous cases, and leave feedback on issues we've solved! You can also drop us a line at to start a new case.

If you're looking for more immediate or emergency assistance, you can also call us. Find your country's phone number.

Plus, you can monitor our system status at

Who can contact us?

In order to provide you with 24x7x365 coverage, Duo Security requests that you identify a dedicated point of contact who will be available until the issue is resolved.

Duo Security requires that only administrators listed in the Duo Admin Panel contact Duo Support. For security purposes, we will be unable to work with non-admins or individuals residing outside of your organization without a Duo Administrator listed on that account present.

If resolution requires any specific personnel from your organization (i.e network engineers), please have them available to troubleshoot critical severity issues when contacting Duo.
