# Manage the TLS certificate using the GUI

Upon system installation, the cluster's TLS certificate is activated with an auto-generated self-signed certificate, enabling access to the GUI, CLI, and API via HTTPS. If you have a custom TLS certificate, you may replace the auto-generated self-signed certificate with your own. Additionally, you can download the existing TLS certificate for integration with other applications that require communication with the cluster, such as Local WEKA Home.
