Single Connect integrates with Cisco Duo via API, as long as certain parameters are defined in Single Connect:

-
  API key (the API key is created by Duo for each customer environment)
-
  URL (the URL is unique for each customer environment)
-
  Integration key (the integration key is created by Duo for each customer environment)


To adjust the Duo Integration Settings:

1. Navigate to **Administration** > **System Config Manager**.
2. Set the following parameters:
   mfa.provider=duo (default: internal)
   mfa.external.provider.duo.api.hostname=XXX 
   mfa.external.provider.duo.integration.key=XXX 
   mfa.external.provider.duo.secret.key=XXX (encrypted)
   mfa.external.provider.duo.factor = \{passcode, sms, push}
   mfa.external.provider.duo.push.type = "the message which will be shown in the push notification on mobile device" default: **Single Connect MFA Request**

- With Duo enabled, the token can be sent in different ways:

| **Passcode** | Token in the mobile app is used.                       |
| ------------ | ------------------------------------------------------ |
| **SMS**      | Token is sent by SMS.                                  |
| **Push**     | Verification is confirmed from the mobile application. |
