As soon as your certificate expires, you will receive an e-mail message from our support 2 weeks before this date. You can then decide whether you want to renew the certificate or let it expire. At the same time you can inform us if your certificate should be renewed automatically in the future (until you explicitly cancel it).
Alternatively, you can renew your certificate automatically via our store on the website. If you need help with the installation, please feel free to contact us. We will help you in any case.
