+# Duo Push Notification
+
+Using mobile push notifications is becoming the new trendy way to validate
+the second factor of a 2FA authentication process. [Duo](https://duo.com/) is offering an API
+to integrate this kind validation and **Authelia** leverages this mechanism
+so that you can simply push a button on your smartphone to be securely granted
+access to your services.
+
+<p align="center">
+  <img src="../../images/2factor_duo.png" width="400">
+</p>
+
+In order to use this feature, you should first create a free account on Duo
+(up to 10 users), create a user account and attach it a mobile device. The name
+of the user must match the name of the user in your internal database.
+Then, click on *Applications* and *Protect an Application*. Then select the option
+called *Partner Auth API*. This will generate an integration key, a secret key and
+a hostname. You can set the name of the application to **Authelia** and then you
+must add the generated information to your configuration as:
+
+    duo_api:
+      hostname: api-123456789.example.com
+      integration_key: ABCDEF
+      secret_key: 1234567890abcdefghifjkl
+
+This can be seen in [config.template.yml](../../config.template.yml) file.
+
+When selecting *Duo Push Notification* at the second factor stage, you will
+automatically receive a push notification on your phone to grant or deny access.

+## Limitations
+
+Users must be enrolled via the Duo Admin panel, they cannot enroll a device from
+**Authelia** yet.
+
+
+## FAQ
+
+### Why don't I have access to the *Duo Push Notification* option?
