How do I revoke my T-CAT?

1. Access the EACAT , specifically in Procedures>Consortium AOC>Digital Certification Service> T-CAT: Request for revocations

2. In the “Initial Information” tab, the revoke certificates option is already selected, so click “Save Draft” to continue.

3. In the "Request data" tab, you can write the data of the certificate to be revoked (the tool will detect the certificate automatically), or you can search for the certificate with the magnifying glass.

If you select the magnifying glass option, the following screen will open:

Fill in the following information:

• "Name" or "NIF/NIE" of the certificate to be revoked.
• The status of the certificate which in our case is "Valid" by default, given that if it is expired it cannot be revoked.
• Select the "Type of certificate"

Click on "Search"

Once the certificate appears, it will be selected and "Select" will be clicked to continue.

4. In the "Request notices" tab, select the reason for revocation and then "Next"

The main reasons for revocation are:

• Compromise of the information contained in the certificate (for example change of subscriber data)
• Compromise of the security of the key or certificate (for example suspected fraudulent use of the certificate or PIN and PUK).
• Compromise of the cryptographic device (eg loss or inoperability of the cryptographic device)
• Reasons relating to the subscriber or the key holder (for example end of the subscriber's contractual relationship or change of the subscriber's data).
• Inclusion in the list of prohibited subscribers (eg inclusion of a subscriber in the list of prohibited subscribers).
• others

5. Then send the request for signature using the "Send for signature" button. The user with the role of applicant for personal certificates must sign the submission from EACAT/My procedures/To sign, by pressing the "Sign" button.

The request will be registered in EACAT and in a few minutes the certificate will be revoked automatically. Once registered in EACAT the revocation enters the system and there is no possibility to undo the request.

To be able to revoke the certificate, you must access the address https://scd.aoc.cat/revocar and add the requested data. If you do not remember the Management Code:

• You can find it in the email in which the PIN and PUK codes were sent to you
• You can find it on the delivery sheet you signed when you received the T-CAT.
• You can recover it by clicking the red link at the bottom of the screen and you can Recover the data to the indicated email address.

The revocation can be done 24 hours a day, 7 days a week.
