Obtaining a Comodo Email Certificate
Below are instructions for obtaining and backing up a Comodo Email Certificate using the Mozilla Firefox browser (recommended). These instructions are for the personal certificate. The process for a business certificate should be similar. We do not recommend Google Chrome because we have had trouble installing Comodo certificates with it. Also see Email,
To install the certificate, see Installing Email Security Certificates on a Workstation. If you need to delete a Comodo certificate, see Revoking a Comodo Email Certificate.
IMPORTANT: Remember the Revocation Password you enter. It is used to delete the certificate in case you need to recreate it. For example, if you created your certificate in Google Chrome by accident, then you can revoke the certificate and create a new certificate using one of the recommended browsers. Once you have filled in the required fields, click Next >.
IMPORTANT: You must open your email from the same browser that you applied for your certificate.
Your certificate backup is now complete. If someone else get this certificate file from you and they also know the password to unlock it, they will be able to read your encrypted messages.
