Is SiteGround ready for 100-day and 47-day certificates?

Renews automatically

SiteGround’s own certificates renew automatically, so the shorter lifetimes (100 days from March 15, 2027, 47 days from March 15, 2029) are handled for you, with the exceptions below.

What renews automatically

• Let's Encrypt certificates (standard and wildcard) are renewed automatically 30 days before expiry.[SiteGround 1 (SiteGround KB — How to manage your SSL certificates in Site Tools), 2 (SiteGround KB — What is Let's Encrypt?)]
• Paid Premium Wildcard certificates are renewed automatically 15 days before expiry.[SiteGround]

What doesn’t

• Imported external certificates can't be renewed through SiteGround. Renew them with their issuer.[SiteGround]

When it renews

Let's Encrypt: 30 days before expiry. Premium Wildcard: 15 days before.[SiteGround]

What to do, and by when

1. March 15, 2027 · In 120 days
   Maximum certificate lifetime drops to 100 days[CA/Browser Forum 1 (CA/Browser Forum — Baseline Requirements for TLS Server Certificates (v2.3.1, 4 Oct 2026)), 2 (CA/Browser Forum — Ballot SC081v3: Introduce Schedule of Reducing Validity and Data Reuse Periods)]
   If you imported a certificate, plan to replace it about every three months from your first renewal after this date, or switch to Let's Encrypt.

Steps

1. In Site Tools, open Security > SSL Manager and check each certificate's type and expiry.
2. Let's Encrypt and Premium Wildcard renew by themselves. Imported certificates need you to renew and re-import them.
