    Helpful first
    Sorry you have to deal with this. You can stay on Let's Encrypt. Here is what to change before February 10, 2027:

1. Check how you renew. Look at your ACME client settings. Note any fixed renewal interval.
2. Turn on ARI or renew earlier. Use an ACME client that supports ARI, or renew about two thirds of the way through each certificate's life.
3. Test on staging first. Let's Encrypt staging gets changes about a month early. Run your renewals there.

    What changes at Let's Encrypt

    From February 10, 2027, Let's Encrypt's default profile issues 64-day certificates. From February 16, 2028, it issues 45-day ones. Renewing every 60 days will no longer be enough.

    • Default certificates become 64 days: February 10, 2027 (Let's Encrypt)
    • Default certificate lifetime from then: 64 days (Let's Encrypt)
    • Authorization reuse from then: 10 days (now 30 days) (Let's Encrypt)
    • Next step: 45-day certificates from February 16, 2028, with 7 hour authorization reuse (Let's Encrypt)
    • Opt-in 45-day profile (tlsserver): Since May 13, 2026 (Let's Encrypt)
    • Fixed renewal timers: Renewing every 60 days will no longer be sufficient (Let's Encrypt)
    • Let's Encrypt recommends: ACME Renewal Information (ARI), or renewing about two thirds of the way through (Let's Encrypt)
    • Staging gets changes: About a month before production (Let's Encrypt)
    • Industry rule (CA/Browser Forum): Maximum validity falls from 398 days to 47 days between March 2026 and March 2029 (CA/Browser Forum)
    • Sites that renew on a fixed 60-day timer: Will have expired certificates (Let's Encrypt)

    You can stay on Let's Encrypt if you make the change. This page is for people who would rather leave.
