# Duo

Configure Duo multifactor authentication in Remote Desktop Manager by linking the Duo Admin Panel to require push, SMS, or phone verification.

Remote Desktop Manager allows you to configure a ***Duo*** authentication to provide an additional security layer when opening a workspace.

{% hint style="info" %}
Before you start the configuration, make sure you have created a Duo account and have also installed the Duo application on your compatible device.
{% endhint %}

1. Log in to the ***Duo Admin Panel***.
2. In ***Applications***, click on ***Protect an Application***.
3. Protect the ***Partner Auth API*** app.
4. If not already done, follow these [multifactor authentication configuration steps](/rdm/getting-started/workspaces/multifactor-authentication.md).
5. After having selected the ***Duo*** MFA type, click ***Duo – General Settings*** (Windows) or ***Apply*** (macOS).
6. All the information necessary to fill in the ***Duo settings*** fields in Remote Desktop Manager will be generated by the Duo account.
7. Copy and paste all the information in the corresponding fields in the ***Duo Settings*** window.
8. Click on ***Check*** to validate the information, then click ***OK*** when done.
9. If there is more than one device connected to the Duo account, click on ***Settings***. If not, skip to step 10.
10. Select the device to use for the multifactor authentication by clicking on ***Use this device***.
11. Select the method by which to receive the Duo Passcode:
    * ***Duo push***: The code is "pushed" to your Duo application.
    * ***Send SMS***: The code is sent by SMS on the registered phone number.
    * ***Phone***: The code is sent by phone call; a computer generated voice will dictate the code.
12. Click ***Save*** to authenticate yourself.

Once you have completed all the steps, you will be prompted with the Duo Authentication every time you connect to your secured workspace.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/rdm/getting-started/workspaces/multifactor-authentication/duo.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
