Get a free Wildcard SSL certificate

Every 1&1 IONOS domain contract comes with a Wildcard SSL certificate included.

Why is SSL important?

An SSL certificate ensures all information transmitted to and from your website is protected from third parties attempting to access it. It is important because internet browsers like Google Chrome mark pages that don't have https and the green padlock in the address bar as not secure. This can have a negative effect on the trustworthiness of your website. Pages that are protected with SSL receive better search engine rankings, and are more likely to be trusted by visitors.

What is a wildcard?

With 1&1 IONOS, your contract comes with a free Wildcard SSL certificate included. Where a standard SSL certificate only protects one domain, a Wildcard SSL certificate protects the domain name, as well as all of the related subdomains, like

.dev domain

Frequently asked questions
The .DEV TLD is a secure namespace, meaning that HTTPS is required for all .DEV websites. You can register your .DEV domain name now, but in order for it to work properly in browsers you must first configure HTTPS serving by configuring a SSL Certificate with your domain name. For each individual domain contract you'll receive a free SSL certificate, which can be easily set up within your Control Panel after the successful domain registration.
