47-Day Certificate Readiness

Certificate lifetimes are shrinking to 47 days by 2029. Is your domain ready for automated renewal?

What's Changing
March 15, 2026 — 200-day maximum
CA/Browser Forum ballot SC-081 reduces maximum certificate lifetime to 200 days.
March 15, 2027 — 100-day maximum
Further reduction to 100 days. Domain validation reuse limited to 200 days.
March 15, 2029 — 47-day maximum
Final reduction. DCV reuse limited to 10 days. Manual management is impossible.

Why This Matters

Manual certificate renewal every 47 days is impractical. Organizations without ACME automation will face outages.

What We Check

Certificate validity period, ACME CA detection, automation indicators, CAA records, and expiry status.

Get Ready Now

Set up certbot, acme.sh, or Caddy for automated ACME certificate issuance before the deadlines hit.
