         The Certbot command generates a private key on your server, creates a Certificate Signing Request (CSR) using that key, and sends the CSR to Infisical for certificate issuance. Certbot stores the private key and resulting leaf certificate and full certificate chain in `/etc/letsencrypt/live/{domain-name}/`.

     <Step title="Renew Your Certificate with Certbot">
         Certbot automatically installs a `systemd` timer during installation. This timer runs twice per day and checks whether any certificates are due for renewal. Because Certbot stores the ACME server URL and EAB credentials from your initial request, renewal will automatically use the same Infisical ACME configuration—no additional settings are required.
