Is Namecheap SSL ready for 100-day and 47-day certificates?
Automatic only in some setups
Partly. Some Namecheap SSL setups renew and install certificates automatically; others need you to act every cycle. See which one you have below.
What renews automatically
- Web-based automation (SSL Proxy): Namecheap hosts a proxy that issues and reissues the certificate every 200 days. Your domain must use Namecheap DNS.[Namecheap]
- Server-side automation (SSL Manager): a one-time setup on cPanel or an Apache/NGINX server with root access adds a cron job that installs each new certificate. Namecheap notes it's not ACME.[Namecheap]
- The Namecheap SSL tool in Namecheap Shared Hosting also reissues automatically.[Namecheap]
What doesn’t
- Certificates in manual mode must be reissued and reinstalled every 200 days. Namecheap emails a reminder 30 days before each required reissue.[Namecheap]
- If you skip a reissue, the plan's timer keeps running and the unused days aren't added back.[Namecheap]
- Automation covers single-domain SSLs activated through Namecheap.com. Server-side automation covers single-domain certificates only.[Namecheap]
When it renews
Manual certificates: reminder email 30 days before each required reissue.[Namecheap]
What to do, and by when
- March 15, 2027 · In 120 daysMaximum 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)]Move manual Namecheap certificates to an automation option, or a free automatic certificate from your host, before your first reissue after this date. From then on, each certificate lasts at most 100 days.

Steps
- In Namecheap, open Account > SSL Certificates and check which mode each certificate uses.
- If it shows web-based automation, server-side automation or the Shared Hosting tool, keep that setup healthy (for the proxy: keep the domain on Namecheap DNS).
- If it's manual, first check whether your host offers a free automatic certificate. If you need the Namecheap certificate, set up SSL Manager (cPanel/Apache/NGINX, single-domain) or SSL Proxy (Namecheap DNS).
- Until it's automated, reissue before each 200-day certificate expires. Unused days are lost if you skip one.
Not published by Namecheap SSL
- Namecheap lists ACME and "automated issuance with manual installation" as "scheduled for November – December 2026". We couldn't confirm whether they're live yet.
- The same Namecheap page gives two rollout windows for wildcard/multi-domain automation ("March through June 2026" and "by November – December 2026"). Current status unknown.
We re-check these every month.
Dated note
Namecheap's page dates the 200-day limit to "March 12, 2026". The industry rule took effect March 15, 2026; some CAs switched a few days early.[Namecheap; CA/Browser Forum; Sectigo; SSL.com]
Questions
I bought a 5-year Namecheap SSL. Why did I get a certificate for only about 200 days?
Namecheap says a multi-year plan is a prepaid series of 200-day certificates under the industry limit. Each one is issued at no extra charge until your term is covered.
What happens if I don't reissue my Namecheap certificate in time?
HTTPS stops working when the current certificate expires. Namecheap says the subscription timer keeps running and the unused days aren't added to the end of the plan.
Does Namecheap support ACME?
Namecheap lists ACME as "scheduled for November – December 2026". Its SSL Manager option automates installation but isn't ACME.
