Let's Encrypt on a Mac
Free TLS certificates via ACME — health & renewal monitor · Secrets & Vaults
Let's Encrypt issues free, automated TLS certificates over the ACME protocol (RFC 8555), proving domain control with HTTP-01 or DNS-01 challenges. Clients like certbot and acme.sh renew certificates when 30 days remain — so a live cert inside that window means your renewal automation is broken. This pane watches the ACME API, Let's Encrypt's status page, and a domain's certificate: it alerts when renewal is overdue. Issue certificates with the New Site wizard, the AI Administrator's issue_certificate tool, or acme.sh/certbot directly.
