Configuring A Free Certificate for A Domain Name


If you haven’t purchased an HTTPS certificate for the website, and the accelerated domain names do not contain any wildcard domain name, you can configure a free certificate.
1. Free Certificates are issued by the Let's Encrypt. If your site is currently accessed through NS, you can apply for a wildcard domain name certificate. If it is accessed through CNAME, EdgeOne only supports the application of single domain name certificates and does not support the application of wildcard domain name certificates.
2. The certificate has a validity period of 3 months. The platform will automatically apply for renewal before expiry, so there is no need for you to manually update it. If you are currently using NS access and switch to CNAME access, the applied wildcard domain name certificate will not be able to auto-renew upon expiration.
3. Free certificates do not support downloading.
4. For domain names connected via the CNAME, you need to configure CNAME and wait till the CNAME takes effect.


1. Log in to the EdgeOne console. Click the target site in the site list to display second-level menus for site management.
2. In the left sidebar, click Domain Name Service > Domain Management.
3. In the domain name list that appears, find the domain name for which the certificate is to be configured and click Edit in the HTTPS column of the domain name.

4. Set Certificate type to Free certificate and click OK. Then the free certificate is delivered and installed.
5. In the domain name list, hover over the icon before Configured in the record of the target domain name, and you can see the information of the deployed certificate.
