The domain provider should offer a way to renew the certificate. Through DNSimple for example first click on the domain scroll to the SSL Certificates area and click the button to renew SSL Certificate. The domain provider will ask what email to send the validation email to. This are pre determined emails that usually the person who bought the certificate will setup. Choose a persons email (if not yours or the company’s) that you have contact with.
The SSL provider will send the email to the email you previously chose. This email usually takes a few minutes to deliver. If you are not the person it send the email to instruct the person to validate the request.
There will be clear instructions on the email of how to validate the request. Usually the SSL provider will provide a link with a “validation code”. Click the link to validate the request, copy the validation code, and and paste the validation code in the input provided by the SSL provider’s website.
The SSL certificate provider might send you an email for your SSL site seal. This seal is for you to put on the website (optionally) to demonstrate your customers that the site is secure.
The SSL provider will send you a link or attachments of the SSL certificates. Download the certificates to your computer.
There will be multiple certificates associated with the domain.
