# 4.6 RabbitMQ configuration

**ZTrust** uses **RabbitMQ** to establish connectivity with the **ZTrust** **Authenticator** app for Push Notifications, NFC-based login, QR code login and other authentication methods. Hence the **RabbitMQ** node should be accessible from **ZTrust SSO** and should be able to accept connections via MQTT and secured MQTT protocol.

To configure **RabbitMQ** in **ZTrust**, 

Navigate to the realm where you want to apply the **RabbitMQ** configuration. And select the **Realm settings**
