It is not possible to simply extend the expiry date of an existing HTTPS certificate. Instead you must replace the certificate with a new one.
However to maintain the security of your website you will want to replace the existing certificate before it expires. If you purchase a new certificate it will be valid from the date of issuance and you will effectively lose the remaining days on the current certificate.
To prevent the loss of these days it is possible renew a certificate up to 90 days before it expires. Renewing a certificate means you still order a new certificate but any remaining days on the existing certificate are added to the new certificate.
You can renew a certificate using any account. It does not need to be done using the same account. However the common name must be exactly the same.
To renew a Sectigo Certificate simply generate an order for the certificate you want then during configuration select the Renewal option. Provided the domain name of the new certicicate is the same as the original then up to an additional 90 days will be added to your certificate.
You can renew any brand of certificate with a Sectigo or PositiveSSL certificate.
RapidSSL, Geotrust, Thawte and DigiCert certificates can only be renewed with the same provider they were originally purchased from. The domain name must be the same as the original certificate.
To renew you must provide the order token from the original order.
The renewal restrictions on RapidSSL, Geotrust, Thawte and DigiCert are put in place by the CACA - This is the Certificate Authority. The Certificate Authority is trusted by browsers and operating systems to issue certificates. Certificates issued by a trusted CA are trusted by all major browsers and operating systems. and we are unable to bypass them
