2. What does the Warranty actually mean?
We believe it is important to protect the end user. If we were to mis-issue a certificate to a fraudulent site, and that fraudulent site has an SSL link with an end user, the end user loses money. The end user had what they thought was a "trusted session". Comodo should never have provided the fraudster with the ability to engineer this situation. Hence, we have taken out insurance to pay out money to the end user. Why do we do this?
- We value the end customer
- We believe the insurance provided greater peace of mind hence allows the merchant to sell more products
- We value our validation techniques (delivered through the IDAuthority)
We pre-validate customers and provide validation that is higher than the majority of other SSL providers. Some CA's have very weak validation (hence they decide NOT to offer insurance). Finally, Comodo offers offer high validation, but not at the compromise of speed. You can still obtain SSL instantly. To see the warranty offered on each of our SSL Certificates, click here.
3. Why do you ask for documentation for when I apply for InstantSSL or EV certificates?
Comodo recognizes that strong validation is essential for the continuing growth of ecommerce. Before issuing certain types of certificate like InstantSSL or EV SSL, we validate both that the applicant owns, or has legal right to use, the domain name featured in the application, and secondly, that the applicant is a legitimate and legally accountable entity. To do this, we need to have access to documentation which verifies these two factors.

4. Why does the website say the SSL certificate is 'Untrusted'?
The usual cause of this is that the Comodo intermediate certificate has not been loaded.
5. Why does the secure part of the website say the name on the security certificate is invalid or does not match the name of the site?
This is often caused by the certificate having a Common Name of "domain.com" and the customer is going to "www.domain.com". PositiveSSL customers will never experience this issue because all PositiveSSL certifcates secure both www.domain.com and domain.com.
6. When trying to go to the site over https it displays the message 'The page cannot be displayed'?
Usually caused by port 443 not allowed through firewall or by the SSL certificate not having a corresponding key file.
7. The CSR cannot be decoded?
This is because it is missing one or more required fields or the CSR contains non-alphanumeric characters in the required fields.
8. I cannot remember or have lost my login details.
If you still have the order number, they can use the automated password reminder system; if not, you must send an email from the administrative email address on the account to firstname.lastname@example.org (be sure to include the original domain name it was purchased for, or the original order number).
9. I have accidentally deleted my "private key". What can I do now?
First check your backups and see if you can re-install the "private key". If you don't know how to re-install the key from your backups, contact your systems administrator. Failing that, contact your web server software vendor for technical support. The only alternative course of action available is a re-issuance of the certificate following the re-submitting of a replacement CSR.
10. I have changed my server, or moved to a different provider; how do I move the certificate?
The easiest way is to create a new CSR on the new machine and have the certificate re-issued.
