Important Information

In the case where hardware is issued, ONLY THE SUBSCRIBER OF THE CERTIFICATE SHOULD HAVE EXCLUSIVE USE OF THEIR TOKEN OR SMART CARD – In all cases, THE DIGITAL CERTIFICATE IS YOUR FORM OF IDENTIFICATION, SIMILAR TO YOUR PASSPORT OR DRIVER’S LICENSE. Under the ECA Certificate Policy, it is our responsibility as an Authorized Certification Authority to revoke the certificate in a case of hardware loss or disclosure or compromise of the private key or any certificate related password to anyone other than the subscriber.
