CoG uses an Earth System Grid Federation (ESGF) OpenID as its authentication mechanism.
If you have an old CoG username and password, but no ESGF OpenID, you will need to request one.
The SSL certificate used by ESGF is self-signed. Some browsers have difficulty with this certificate and users will need to tell their browser to trust it.
