Managing Certificates
3 minute read.
The Certificates screen shows information for certificates, certificate signing requests (CSRs), and ACME DNS-authenticators configured on the system, and provides the ability to import or edit them. TrueNAS comes equipped with an internal, self-signed certificate that enables encrypted access to the web interface, but users can make custom certificates for authentication and validation while sharing data.
The TrueNAS Connect service automatically creates a default truenas_connect_ certificate after registering your TrueNAS system in the TrueNAS Connect service. The certificate shows in the Certificates widget on the Credentials > Certificates screen.
This certificate provides secure SSL access between the TrueNAS server and the TrueNAS Connect service. If not listed on the Certificates screen, choose the truenas_default certificate. For apps where certificates are used, you should see and be able to select the TNC certificate and get a full secure connection for the apps.
