SSL Certificates
TiiPanel can issue free certificates automatically for hosted domains, or you can upload your own.
Automatic issuance
Enable automatic certificate issuance at Admin → Settings → SSL. New domains (and the panel's own hostname) get a certificate issued automatically once DNS resolves to the server, and renewal is handled on a schedule — no cron setup needed beyond what the installer already configured.
Custom certificates
Upload a certificate and private key for a specific domain from that account's SSL tab if you need an EV certificate or one from a specific CA.
Securing the panel itself
Don't forget to put a real certificate on the panel's own hostname (not just hosted customer domains) — see the Post-Install Checklist.
