# Introduction

Before connecting to the deployments, you need to complete the required operations for Viewing Deployment to obtain the necessary information such as the deployment connection address and connection port. At the same time, you also need to add client connection authentication information in the EMQ X Dashboard authentication and ACL.

For basic EMQ X Cloud deployment , it provides TLS/SSL connection authentication by default, and you may also need to download root certificate (opens new window) for TLS/SSL connection.
