As of March 15, 2026, all SSL certificates have a maximum validity of 199 days. This is an industry-wide change enforced by all Certificate Authorities, including DigiCert. Your subscription and billing are not affected — certificates purchased annually or for multiple years remain the same price. However, your certificate must now be reissued and reinstalled partway through the subscription term to stay valid.
This guide explains what to expect and what action you need to take.
Your SSL subscription covers the full term you purchased. What changes is that the certificate installed on your server expires at 199 days and must be reissued and reinstalled before that point. The validity period will continue to shorten over the next few years:
| Effective Date | Maximum Certificate Validity |
|---|---|
| March 15, 2026 | 199 days |
| March 15, 2027 | 100 days |
| March 15, 2029 | 47 days |
WHMCS will automatically reissue your certificate as it approaches expiration. You will receive an email notification when the reissued certificate is ready.
Reissuance is automatic — installation is not. Once reissued, the new certificate must be installed on your server before the current one expires.
Open a support ticket and our team will install the reissued certificate on your server.
You will need to install the certificate manually. Follow these steps:
Install the certificate using the private key associated with your CSR. Follow your server or control panel's instructions to complete the installation.
If you need to reissue your certificate manually (for example, if your private key was compromised), you will need to generate a new CSR and private key first. On Linux, use the following command:
openssl req -new -newkey rsa:2048 -nodes -keyout your.domain.key -out your.domain.csrThen follow the steps in our guide: How to Reissue an SSL Certificate.
