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

Renews automatically

Squarespace’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

• All domains correctly pointing to a Squarespace site get free SSL automatically. Let's Encrypt certificates are refreshed every 90 days.[Squarespace]

What doesn’t

• Squarespace doesn't support third-party certificates or ACME.[Squarespace]

When it renews

Unknown: Squarespace doesn’t say how far ahead it renews.

What to do, and by when

1. February 10, 2027 · In 87 days
   Let's Encrypt default certificates drop to 64 days[Let's Encrypt 1 (Let's Encrypt — Decreasing Certificate Lifetimes to 45 Days (Dec 2, 2025)), 2 (Let's Encrypt — 64-Day Certificate Lifetimes Coming Feb 2027 (Oct 7, 2026))]
   Nothing to do. Keep the domain pointing to Squarespace.

Steps

1. Open your domains dashboard and check the SSL status shows as issued/active.
2. If not, fix the domain connection (DNS records) and wait up to 48 hours.
