Creating ACME Certificates
TrueNAS allows users to automatically generate custom domain certificates using Let’s Encrypt.
- An email address for your TrueNAS admin user.
- A custom domain that uses Cloudflare, DigitalOcean, Amazon Route 53, or OVHcloud.
- A DNS server that does not cache for your TrueNAS system.
Go to Credentials > Certificates and click ADD in the ACME DNS-Authenticators widget.
