+Amazon MQ supports mutual TLS (mTLS) for RabbitMQ brokers. The [SSL authentication plugin](https://github.com/rabbitmq/rabbitmq-auth-mechanism-ssl) uses client certificates from mTLS connections to authenticate users. This plugin is conditionally enabled based on your broker configuration. When enabled, it provides certificate-based authentication using X.509 client certificates for strong authentication without transmitting credentials over the network. For more information about SSL certificate authentication, see [SSL certificate authentication](./ssl-for-amq-for-rabbitmq.html).
