Using a Sectigo certificate on an external site (another hosting provider)

Update 08/03/2026

This guide details the conditions and procedure for using an Infomaniak Sectigo certificate on a website hosted elsewhere, with a third-party hosting provider.

 

Introduction

 

Install a Sectigo certificate

Due to the different providers, the installation of your certificate will not be automatic:

1. Obtain the CSR

Export the CSR configuration file from your hosting provider and enter it in the certificate request form at Infomaniak.

2. Confirm domain ownership

Validate the domains included in the certificate using one of the following methods:

  • Enter a validation code received at one of the following email addresses (the complete email address must exist on the domain to be validated, e.g., “domain.xyz”):
    • admin@domain.xyz
    • administrator@domain.xyz
    • hostmaster@domain.xyz
    • postmaster@domain.xyz
    • webmaster@domain.xyz
  • Create a unique CNAME record in the domain's DNS.
  • Upload the validation .txt file via FTP to your site.
