Comodo (or Sectigo) SSL certificate can be installed in a couple of easy steps, described below.

Step 1 - Activate the order

After you purchase the Comodo SSL certificate, you will see it in your Dashboard - just click on Setup in front of the order. Then insert the contact information:

When SSL is set up, it has to be verified via email which is sent to the mailbox of admin@yourdomain.tld.


  • If you happen to not have this mailbox, you can easily create it and resend the verification email by clicking Resend approval email

  • If you do not have a possibility to create such an inbox, contact our Customer Success team for an alternative verification method

Step 2 - Verify domain

Enter your mailbox (admin@yourdomainname.tld) to verify the SSL certificate and find an email from Sectigo. You will need to copy a verification code and then open the linked website:

On the website, enter your verification code to the field and click Next. Your domain will be verified shortly.

Step 3 - Download and install certificate

If you wish to install an SSL certificate at Hostinger Shared, Cloud, or WordPress hosting, open your SSL page again and click on Manage in front of the certificate:

And then choose Install:

If you wish to install the certificate on VPS or elsewhere, you would need to download the certificate’s files, which can be done from the SSL page:


  • For security reasons, the archive with certificate files, which you received by email, does not contain a key. No worries, an archive, which you are downloading from hPanel, provides all the needed files 👍

For the installation process, you would need to follow instructions designed for the control panel you are using. In most panels, you will need to see 3 fields: Certificate, Private Key, and Certificate authority bundle. All the fields need to be filled out in order to successfully install Comodo SSL!


Private Key

Certificate authority bundle

The certificate’s public key from the file named yourdomainname.crt

The only file with the ending .key on the zipped folder

Content of these files one by one:





  • In case you wish to renew your Comodo SSL, you will need to uninstall the previous certificate, purchase a new one and install it
