If I renew within 60 days of my certificate expiring, can I get the new certificate to include the lost days?

Yes. We have automated the renewals process to begin alerting you up to 60 days prior to your SSL Certificate expiring. Please click on the renewal link inside your renewal reminder e-mail. However, the renewal emails are sent only to customers who came direct to Comodo and not those who came via a reseller partner of Comodo. Please note that during the renewal process you will require a new CSR

I did not get the renewal email; can I still get the extra days?

Yes, if you have changed e-mail address and therefore have not received a reminder, then you will need to log in to your account area to renew the certificate.

Are there situations where I will not get the extra days on my certificate?

Buying a new certificate through the normal online purchasing screens will not automatically add extra days.

What do I need to renew an SSL certificate?

You will need a new CSR for the domain and your user name/password.

What if I do not remember the user name/password?

If the problem is just the password, then as long as you have the order number and either account email address or user name, this can be automatically reset by visiting and clicking on the 'forgotten password' link. If you do not have the details required above, please send an email, from the account administrative email address to with as much detail as possible so that we can locate your order.

I get an error saying 'Account Already Exists'. What does this mean?

This error means that there is already an order on our system for the required domain. It can also mean that you have not signed into your account before placing the order.

Can I use my old CSR?

Some web servers will allow this, but we recommend a new CSR for every renewal.

Some details have changed since my last order. How do I get these updated?

All account changes should be sent to

How do I renew my certificate?

First, create the CSR Then sign into your account, and if available, select the Get/Renew SSL link. This will take you to the products page where you select the required product and options.
If the Get/Renew button is not available, select the required product, then the options, and when presented with the page for the CSR, sign into your account at this point.
If you purchased through a reseller, please contact the reseller.

Do I need to install the new certificate you send me?

Yes, the dates are hard-coded into the SSL Certificate, so for the site to present the correct certificate, the new one must be installed.

Can I simply extend the dates on my old certificate?

No, the dates are hard-coded into the certificate and cannot be changed
