How do I assign my Gen 1 SSL Certificate to a domain?

This article will show you how to assign your Generation 1 SSL certificate to a domain name.

Please note: this article only applies to SSL certificates purchased before September 2021.

Step 1 of 8

Start by logging in to your 123 Reg Control Panel.


Step 2 of 8

From there, select SSL Certificates within the ‘Manage active products’ section and then select Manage opposite Manage SSL Certificates.

Manage SSL Certificates


Step 3 of 8

This will take you to the SSL overview page, where you will see all your purchased SSL certificates.

If you haven’t already done so, select the Generation 1 tab.

Select Generation 1


Step 4 of 8

From here, click Options for the SSL certificate you wish to set up and then choose Assign from the drop-down menu that appears.

Click Assign


Step 5 of 8

This will open a pop-up window where you’ll need to enter the domain name you want to assign your certificate to. Once you’ve done this, click Go to continue.

Enter domain name


Step 6 of 8

Enter your details, the approval email address and your CSR (if the domain is not with 123 Reg/about to be installed on hosting packages).

The approval email address you select must be created prior to completing the assigning process as it’s used as part of the domain validation process (you will receive an email to it to confirm the order as the domain owner)


Once you’ve entered your details, tick the box to agree to our general terms and then click Save to continue.

Enter details

Please note: During the order process, if you are purchasing an SSL certificate to use in conjunction with a 123 Reg hosting package, please choose the auto CSR option and follow the on-screen instructions. If you are purchasing an SSL certificate as a standalone product, you will need to have your CSR ready. It is recommended for the CSR to be generated on the server (at the hosting provider) where the certificate will be installed.


Step 7 of 8

You will then return to the SSL overview page, where your certificate will now state the message: ‘Order is in progress’

Await SSL certificate


Step 8 of 8

An email will now be sent to the approval email address you selected during the order process. Simply click the link provided in this email to complete your SSL certificate order.

Please note: if you are purchasing an SSL certificate as a standalone product, you will need to install the SSL certificate yourself.

If, however, you are purchasing an Organisation SSL or an Extended SSL, you will be contacted by Starfield Technologies (our Certificate Authority) via the contact information you provided during the purchase procedure. Please be aware that our partners’ vetting procedures are compulsory and their ruling in the matter is final.
