# Manage EMV CRLs
To manage EMV CRLs, a user with an officer role can navigate to the "Manage EMV CRLs" page which displays a grid of available certificates.
If the user wants to revoke a certificate, they can do so by selecting the "Revoke" icon located in the action column. By selecting this icon, a popup screen will appear that prompts the user to fill in certain details such as the Revocation Date, the Revocation Effective Date, and remarks regarding the revocation. Once these details are entered, the user should click on the "Confirm" button to complete the revocation process.
After you click the "Confirm" button, the system will ask you to authenticate. To do this, you need to provide your username and token PIN. Once you have been successfully authenticated, you can click the "Revoke" button to complete the certificate revocation process.
Once the revocation process is completed successfully, you will receive a message displaying the following information.
