How Long Is an SSL Certificate Valid?

An SSL certificate is valid for one year. Once an SSL certificate expires, it cannot be used.

You can renew an SSL certificate before it expires. For details, see Renewing an SSL Certificate.

If you have not enabled auto-renewal, manually renew the certificate or purchase another one 3 to 10 working days before it expires. If you have enabled auto-renewal, check the SMS notifications, and finish required verification 3 to 10 working days before it expires to ensure that the certificate is valid before the CA validates your verification and issues new certificate.

When Does the Certificate Validity Period Start?

A certificate takes effect upon issuance. The certificate issuance time refers to the time when the certificate is officially issued by the CA.

If an additional domain name is added for a multi-domain certificate, the certificate validity period starts from the date when the certificate is issued for the first time.

When Will a Notification Be Sent Before a Certificate Expires?

SCM will notify you of certificate expiration 30 days before the certificate expires.

For certificates you purchase through SCM, SCM automatically notifies you of the expiration by email and SMS two months, one month, one week, three days, and one day before a certificate expires and again when the certificate actually expired.
For uploaded certificates, you need to configure expiration notifications so SCM can notify you of the certificate expiration by email and SMS. For details, see How Do I Configure a Certificate Expiration Notification?

You can renew only paid SSL certificates you have purchased in Huawei Cloud SCM before they are about to expire. For details, see Renewing an SSL Certificate.
